+
+ ISIS-MTT PROFILE: The relatively complex structure of AdmissionSyntax
+ supports the following concepts and requirements:
+
+ - External institutions (e.g. professional associations, chambers, unions,
+ administrative bodies, companies, etc.), which are responsible for granting
+ and verifying professional admissions, are indicated by means of the data
+ field admissionAuthority. An admission authority is indicated by a
+ GeneralName object. Here an X.501 directory name (distinguished name) can be
+ indicated in the field directoryName, a URL address can be indicated in the
+ field uniformResourceIdentifier, and an object identifier can be indicated in
+ the field registeredId.
+ - The names of authorities which are responsible for the administration of
+ title registers are indicated in the data field namingAuthority. The name of
+ the authority can be identified by an object identifier in the field
+ namingAuthorityId, by means of a text string in the field
+ namingAuthorityText, by means of a URL address in the field
+ namingAuthorityUrl, or by a combination of them. For example, the text string
+ can contain the name of the authority, the country and the name of the title
+ register. The URL-option refers to a web page which contains lists with
+ officially registered professions (text and possibly OID) as well as
+ further information on these professions. Object identifiers for the
+ component namingAuthorityId are grouped under the OID-branch
+ id-isis-at-namingAuthorities and must be applied for.
+ - See http://www.teletrust.de/anwend.asp?Id=30200&Sprache=E_&HomePG=0
+ for an application form and http://www.teletrust.de/links.asp?id=30220,11
+ for an overview of registered naming authorities.
+ - By means of the data type ProfessionInfo certain professions,
+ specializations, disciplines, fields of activity, etc. are identified. A
+ profession is represented by one or more text strings, resp. profession OIDs
+ in the fields professionItems and professionOIDs and by a registration number
+ in the field registrationNumber. An indication in text form must always be
+ present, whereas the other indications are optional. The component
+ addProfessionInfo may contain additional applicationspecific information in
+ DER-encoded form.
+
+
+ By means of different namingAuthority-OIDs or profession OIDs hierarchies of
+ professions, specializations, disciplines, fields of activity, etc. can be
+ expressed. The issuing admission authority should always be indicated (field
+ admissionAuthority), whenever a registration number is presented. Still,
+ information on admissions can be given without indicating an admission or a
+ naming authority by the exclusive use of the component professionItems. In
+ this case the certification authority is responsible for the verification of
+ the admission information.
+
+
+
+ This attribute is single-valued. Still, several admissions can be captured in
+ the sequence structure of the component contentsOfAdmissions of
+ AdmissionSyntax or in the component professionInfos of Admissions. The
+ component admissionAuthority of AdmissionSyntax serves as default value for
+ the component admissionAuthority of Admissions. Within the latter component
+ the default value can be overwritten, in case that another authority is
+ responsible. The component namingAuthority of Admissions serves as a default
+ value for the component namingAuthority of ProfessionInfo. Within the latter
+ component the default value can be overwritten, in case that another naming
+ authority needs to be recorded.
+
+ The length of the string objects is limited to 128 characters. It is
+ recommended to indicate a namingAuthorityURL in all issued attribute
+ certificates. If a namingAuthorityURL is indicated, the field professionItems
+ of ProfessionInfo should contain only registered titles. If the field
+ professionOIDs exists, it has to contain the OIDs of the professions listed
+ in professionItems in the same order. In general, the field professionInfos
+ should contain only one entry, unless the admissions that are to be listed
+ are logically connected (e.g. they have been issued under the same admission
+ number).

+ P1363 7.2.1 ECSVDP-DH
+
+ ECSVDP-DH is Elliptic Curve Secret Value Derivation Primitive,
+ Diffie-Hellman version. It is based on the work of [DH76], [Mil86],
+ and [Kob87]. This primitive derives a shared secret value from one
+ party's private key and another party's public key, where both have
+ the same set of EC domain parameters. If two parties correctly
+ execute this primitive, they will produce the same output. This
+ primitive can be invoked by a scheme to derive a shared secret key;
+ specifically, it may be used with the schemes ECKAS-DH1 and
+ DL/ECKAS-DH2. It assumes that the input keys are valid (see also
+ Section 7.2.2).

+ P1363 7.2.2 ECSVDP-DHC
+
+ ECSVDP-DHC is Elliptic Curve Secret Value Derivation Primitive,
+ Diffie-Hellman version with cofactor multiplication. It is based on
+ the work of [DH76], [Mil86], [Kob87], [LMQ98] and [Kal98a]. This
+ primitive derives a shared secret value from one party's private key
+ and another party's public key, where both have the same set of EC
+ domain parameters. If two parties correctly execute this primitive,
+ they will produce the same output. This primitive can be invoked by a
+ scheme to derive a shared secret key; specifically, it may be used
+ with the schemes ECKAS-DH1 and DL/ECKAS-DH2. It does not assume the
+ validity of the input public key (see also Section 7.2.1).
+
+ Note: As stated P1363 compatibility mode with ECDH can be preset, and
+ in this case the implementation doesn't have a ECDH compatibility mode
+ (if you want that just use ECDHBasicAgreement and note they both implement
+ BasicAgreement!).

+
+ A participant in a Password Authenticated Key Exchange by Juggling (J-PAKE) exchange.
+
+ The J-PAKE exchange is defined by Feng Hao and Peter Ryan in the paper
+
+ "Password Authenticated Key Exchange by Juggling, 2008."
+
+ The J-PAKE protocol is symmetric.
+ There is no notion of a client or server, but rather just two participants.
+ An instance of JPakeParticipant represents one participant, and
+ is the primary interface for executing the exchange.
+
+ To execute an exchange, construct a JPakeParticipant on each end,
+ and call the following 7 methods
+ (once and only once, in the given order, for each participant, sending messages between them as described):
+
+ CreateRound1PayloadToSend() - and send the payload to the other participant
+ ValidateRound1PayloadReceived(JPakeRound1Payload) - use the payload received from the other participant
+ CreateRound2PayloadToSend() - and send the payload to the other participant
+ ValidateRound2PayloadReceived(JPakeRound2Payload) - use the payload received from the other participant
+ CalculateKeyingMaterial()
+ CreateRound3PayloadToSend(BigInteger) - and send the payload to the other participant
+ ValidateRound3PayloadReceived(JPakeRound3Payload, BigInteger) - use the payload received from the other participant
+
+ Each side should derive a session key from the keying material returned by CalculateKeyingMaterial().
+ The caller is responsible for deriving the session key using a secure key derivation function (KDF).
+
+ Round 3 is an optional key confirmation process.
+ If you do not execute round 3, then there is no assurance that both participants are using the same key.
+ (i.e. if the participants used different passwords, then their session keys will differ.)
+
+ If the round 3 validation succeeds, then the keys are guaranteed to be the same on both sides.
+
+ The symmetric design can easily support the asymmetric cases when one party initiates the communication.
+ e.g. Sometimes the round1 payload and round2 payload may be sent in one pass.
+ Also, in some cases, the key confirmation payload can be sent together with the round2 payload.
+ These are the trivial techniques to optimize the communication.
+
+ The key confirmation process is implemented as specified in
+ NIST SP 800-56A Revision 1,
+ Section 8.2 Unilateral Key Confirmation for Key Agreement Schemes.
+
+ This class is stateful and NOT threadsafe.
+ Each instance should only be used for ONE complete J-PAKE exchange
+ (i.e. a new JPakeParticipant should be constructed for each new J-PAKE exchange).

+ A pre-computed prime order group for use during a J-PAKE exchange.
+
+ Typically a Schnorr group is used. In general, J-PAKE can use any prime order group
+ that is suitable for public key cryptography, including elliptic curve cryptography.
+
+ See JPakePrimeOrderGroups for convenient standard groups.
+
+ NIST publishes

+
+
+
+ Constructs a new JPakePrimeOrderGroup.
+
+ In general, you should use one of the pre-approved groups from
+ JPakePrimeOrderGroups, rather than manually constructing one.
+
+ The following basic checks are performed:
+
+ p-1 must be evenly divisible by q
+ g must be in [2, p-1]
+ g^q mod p must equal 1
+ p must be prime (within reasonably certainty)
+ q must be prime (within reasonably certainty)
+
+ The prime checks are performed using BigInteger#isProbablePrime(int),
+ and are therefore subject to the same probability guarantees.
+
+ These checks prevent trivial mistakes.
+ However, due to the small uncertainties if p and q are not prime,
+ advanced attacks are not prevented.
+ Use it at your own risk.
+
+ Throws NullReferenceException if any argument is null. Throws
+ InvalidOperationException is any of the above validations fail.

+
+ http://www.cs.ucdavis.edu/~rogaway/papers/eax.pdf
+
+ EAX is an AEAD scheme based on CTR and OMAC1/CMAC, that uses a single block
+ cipher to encrypt and authenticate data. It's on-line (the length of a
+ message isn't needed to begin processing it), has good performances, it's
+ simple and provably secure (provided the underlying block cipher is secure).
+
+ Of course, this implementations is NOT thread-safe.

+ data is incrementally produced with each call to ProcessByte or ProcessBytes. This is
+ important to consider during decryption: in a streaming mode, unauthenticated plaintext
+ data may be output prior to the call to DoFinal that results in an authentication failure.

+
+
+
+ This message notifies the recipient that the sender will not send any more messages on this
+ connection. Note that as of TLS 1.1, failure to properly close a connection no longer
+ requires that a session not be resumed. This is a change from TLS 1.0 ("The session becomes
+ unresumable if any connection is terminated without proper close_notify messages with level
+ equal to warning.") to conform with widespread implementation practice.
+
+
+ An inappropriate message was received. This alert is always fatal and should never be
+ observed in communication between proper implementations.
+
+
+ This alert is returned if a record is received with an incorrect MAC. This alert also MUST be
+ returned if an alert is sent because a TLSCiphertext decrypted in an invalid way: either it
+ wasn't an even multiple of the block length, or its padding values, when checked, weren't
+ correct. This message is always fatal and should never be observed in communication between
+ proper implementations (except when messages were corrupted in the network).
+
+
+ This alert was used in some earlier versions of TLS, and may have permitted certain attacks
+ against the CBC mode [CBCATT]. It MUST NOT be sent by compliant implementations.
+
+
+ A TLSCiphertext record was received that had a length more than 2^14+2048 bytes, or a record
+ decrypted to a TLSCompressed record with more than 2^14+1024 bytes. This message is always
+ fatal and should never be observed in communication between proper implementations (except
+ when messages were corrupted in the network).
+
+
+ The decompression function received improper input (e.g., data that would expand to excessive
+ length). This message is always fatal and should never be observed in communication between
+ proper implementations.
+
+
+ Reception of a handshake_failure alert message indicates that the sender was unable to
+ negotiate an acceptable set of security parameters given the options available. This is a
+ fatal error.
+
+
+ This alert was used in SSLv3 but not any version of TLS. It MUST NOT be sent by compliant
+ implementations.
+
+
+ A certificate was corrupt, contained signatures that did not verify correctly, etc.
+
+
+ A certificate was of an unsupported type.
+
+
+ A certificate was revoked by its signer.
+
+
+ A certificate has expired or is not currently valid.
+
+
+ Some other (unspecified) issue arose in processing the certificate, rendering it
+ unacceptable.
+
+
+ A field in the handshake was out of range or inconsistent with other fields. This message is
+ always fatal.
+
+
+ A valid certificate chain or partial chain was received, but the certificate was not accepted
+ because the CA certificate could not be located or couldn't be matched with a known, trusted
+ CA. This message is always fatal.
+
+
+ A valid certificate was received, but when access control was applied, the sender decided not
+ to proceed with negotiation. This message is always fatal.
+
+
+ A message could not be decoded because some field was out of the specified range or the
+ length of the message was incorrect. This message is always fatal and should never be
+ observed in communication between proper implementations (except when messages were corrupted
+ in the network).
+
+
+ A handshake cryptographic operation failed, including being unable to correctly verify a
+ signature or validate a Finished message. This message is always fatal.
+
+
+ This alert was used in some earlier versions of TLS. It MUST NOT be sent by compliant
+ implementations.
+
+
+ The protocol version the client has attempted to negotiate is recognized but not supported.
+ (For example, old protocol versions might be avoided for security reasons.) This message is
+ always fatal.
+
+
+ Returned instead of handshake_failure when a negotiation has failed specifically because the
+ server requires ciphers more secure than those supported by the client. This message is
+ always fatal.
+
+
+ An internal error unrelated to the peer or the correctness of the protocol (such as a memory
+ allocation failure) makes it impossible to continue. This message is always fatal.
+
+
+ This handshake is being canceled for some reason unrelated to a protocol failure. If the user
+ cancels an operation after the handshake is complete, just closing the connection by sending
+ a close_notify is more appropriate. This alert should be followed by a close_notify. This
+ message is generally a warning.
+
+
+ Sent by the client in response to a hello request or by the server in response to a client
+ hello after initial handshaking. Either of these would normally lead to renegotiation; when
+ that is not appropriate, the recipient should respond with this alert. At that point, the
+ original requester can decide whether to proceed with the connection. One case where this
+ would be appropriate is where a server has spawned a process to satisfy a request; the
+ process might receive security parameters (key length, authentication, etc.) at startup, and
+ it might be difficult to communicate changes to these parameters after that point. This
+ message is always a warning.
+
+
+ Sent by clients that receive an extended server hello containing an extension that they did
+ not put in the corresponding client hello. This message is always fatal.
+
+
+ This alert is sent by servers who are unable to retrieve a certificate chain from the URL
+ supplied by the client (see Section 3.3). This message MAY be fatal - for example if client
+ authentication is required by the server for the handshake to continue and the server is
+ unable to retrieve the certificate chain, it may send a fatal alert.
+
+
+ This alert is sent by servers that receive a server_name extension request, but do not
+ recognize the server name. This message MAY be fatal.
+
+
+ This alert is sent by clients that receive an invalid certificate status response (see
+ Section 3.6). This message is always fatal.
+
+
+ This alert is sent by servers when a certificate hash does not match a client provided
+ certificate_hash. This message is always fatal.
+
+
+ If the server does not recognize the PSK identity, it MAY respond with an
+ "unknown_psk_identity" alert message.
+
+
+ If TLS_FALLBACK_SCSV appears in ClientHello.cipher_suites and the highest protocol version
+ supported by the server is higher than the version indicated in ClientHello.client_version,
+ the server MUST respond with a fatal inappropriate_fallback alert [..].

+ Class representing a simple version of a big decimal. A
+ SimpleBigDecimal is basically a
+ {@link java.math.BigInteger BigInteger} with a few digits on the right of
+ the decimal point. The number of (binary) digits on the right of the decimal
+ point is called the scale of the SimpleBigDecimal.
+ Unlike in {@link java.math.BigDecimal BigDecimal}, the scale is not adjusted
+ automatically, but must be set manually. All SimpleBigDecimals
+ taking part in the same arithmetic operation must have equal scale. The
+ result of a multiplication of two SimpleBigDecimals returns a

+
+
+ An immutable sequence of certificates (a certification path).
+
+ This is an abstract class that defines the methods common to all CertPaths.
+ Subclasses can handle different kinds of certificates (X.509, PGP, etc.).
+
+ All CertPath objects have a type, a list of Certificates, and one or more
+ supported encodings. Because the CertPath class is immutable, a CertPath
+ cannot change in any externally visible way after being constructed. This
+ stipulation applies to all public fields and methods of this class and any
+ added or overridden by subclasses.
+
+ The type is a string that identifies the type of Certificates in the
+ certification path. For each certificate cert in a certification path
+ certPath, cert.getType().equals(certPath.getType()) must be true.
+
+ The list of Certificates is an ordered List of zero or more Certificates.
+ This List and all of the Certificates contained in it must be immutable.
+
+ Each CertPath object must support one or more encodings so that the object
+ can be translated into a byte array for storage or transmission to other
+ parties. Preferably, these encodings should be well-documented standards
+ (such as PKCS#7). One of the encodings supported by a CertPath is considered
+ the default encoding. This encoding is used if no encoding is explicitly
+ requested (for the {@link #getEncoded()} method, for instance).
+
+ All CertPath objects are also Serializable. CertPath objects are resolved
+ into an alternate {@link CertPathRep} object during serialization. This
+ allows a CertPath object to be serialized into an equivalent representation
+ regardless of its underlying implementation.
+
+ CertPath objects can be created with a CertificateFactory or they can be
+ returned by other classes, such as a CertPathBuilder.
+
+ By convention, X.509 CertPaths (consisting of X509Certificates), are ordered
+ starting with the target certificate and ending with a certificate issued by
+ the trust anchor. That is, the issuer of one certificate is the subject of
+ the following one. The certificate representing the
+ {@link TrustAnchor TrustAnchor} should not be included in the certification
+ path. Unvalidated X.509 CertPaths may not follow these conventions. PKIX
+ CertPathValidators will detect any departure from these conventions that
+ cause the certification path to be invalid and throw a
+ CertPathValidatorException.
+
+ Concurrent Access
+
+ All CertPath objects must be thread-safe. That is, multiple threads may
+ concurrently invoke the methods defined in this class on a single CertPath
+ object (or more than one) with no ill effects. This is also true for the List
+ returned by CertPath.getCertificates.
+
+ Requiring CertPath objects to be immutable and thread-safe allows them to be
+ passed around to various pieces of code without worrying about coordinating
+ access. Providing this thread-safety is generally not difficult, since the
+ CertPath and List objects in question are immutable.

+
+
+ This is the default PKIX validity model. Actually there are two variants
+ of this: The PKIX model and the modified PKIX model. The PKIX model
+ verifies that all involved certificates must have been valid at the
+ current time. The modified PKIX model verifies that all involved
+ certificates were valid at the signing time. Both are indirectly choosen
+ with the {@link PKIXParameters#setDate(java.util.Date)} method, so this
+ methods sets the Date when all certificates must have been
+ valid.
+
+
+ This model uses the following validity model. Each certificate must have
+ been valid at the moment where is was used. That means the end
+ certificate must have been valid at the time the signature was done. The
+ CA certificate which signed the end certificate must have been valid,
+ when the end certificate was signed. The CA (or Root CA) certificate must
+ have been valid, when the CA certificate was signed and so on. So the
+ {@link PKIXParameters#setDate(java.util.Date)} method sets the time, when
+ the end certificate must have been valid. It is used e.g.
+ in the German signature law.

+ Sets a List of additional certification path checkers. If

+
+ Each PKIXCertPathChecker specified implements additional

+
+ This method allows sophisticated applications to extend a PKIX

+
+ Regardless of whether these additional PKIXCertPathCheckers are set, a
