Release History

0.7.0 (2025-01-02)

  • Major updates to guard.py:

    • Allow incremental certificate updates using --update (replaces --add)
    • Allow update of only root certificates
    • Add --dry-run to show what actions would be performed without updating PAN-OS
    • Add --show to show managed config
    • Add --update-trusted to fix out of sync trusted root CA certificate settings

  • chainring.py: For HTML document, create hyperlink for certificate fingerprint to crt.sh.

  • chain.py:

    For a root certificate the "Parent Certificate Name" is set to the "CA Owner" field; change node tag to use CA-Owner vs Issuer. Also quote Subject, Issuer, CA-Owner.

  • chainring.py: Add --test-collisions to test for PAN-OS certificate name collisions using the JSON certificate tree as input.

0.6.0 (2024-12-15)

  • Split chain.py into separate programs for:

    • Intermediate certificate determination (chain.py)
    • Certificate download (link.py)

  • Re-implement chain.py to use a tree (using treelib package).

  • Add chainring.py to generate documents from JSON certificate tree.

  • Get CA certificates program (link.py) can use alternate certificate sources before downloading from crt.sh.

  • Allow update of root store only, without adding intermediate certificates.

  • Certificate name on PAN-OS has been changed to 'LINK-[0-9A-F]{26,26}' (sequence number replaced by 'LINK').

  • Add tests for CCADB module.

  • guard.py:

    PAN-257401 is an issue where a specific certificate, when imported as a device certificate and set as a trusted root CA, results in a commit error due to a bad signature. Implement temporary workaround to not import this certificate on --add.

  • sprocket.py: Fix GitHub Issue #3.

0.5.0 (2024-10-07)

  • chain.py: Fix bug where only a single child certificate chain for a root was used.
  • Add To Do List.
  • guard.py: When API import results in expired certificate error, skip that certificate. Allows use of an older certificate archive.
  • chain.py: Remove unneeded else.
  • chain.py: Raise debug level to 3 for revoked and expired logging.
  • chain.py: Fix incorrect indent for saving 'Intermediate with no parent' certificate.
  • Add features to allow a custom root store to replace the PAN-OS root store.

0.4.0 (2024-07-12)

  • ccadb.py: Add functions for 'Derived Trust Bits' to ccadb module.
  • chain.py: Set user-agent header to pan-chainguard/version for crt.sh API.
  • chain.py, guard.py: Generalise some message strings previously specifying PAN-OS to prepare for using other root stores as input.
  • chain.py, ccadb.py: Add pan_chainguard.ccadb module.
  • Documentation improvements and fixes.

0.3.0 (2024-06-12)

  • guard.py: Cache certificate names so we can use a single API request to enable them as trusted root CAs.

  • guard.py: When device is panorama and template specified, perform partial commit with template scope.

  • chain.py: Also retry download on 503 Service Unavailable.

  • guard.py: Fix partial commit using specific admin. In the XML cmd document, <admin> needs to be within <partial> container.

  • guard.py: Simplify Xpath() class.

  • admin-guide.rst:

    chainguard-api admin profile does require type=op because we use synchronous commit in pan.xapi which uses 'show jobs id id-num' to check job status.

  • guard.py: Fix use of panorama from removal of global.

0.2.0 (2024-05-30)

  • guard.py: Add support for import to Panorama Template shared device certificates.

  • chain.py:

    Change 'Server Authentication' not in 'Derived Trust Bits' check to a warning. Safer to leave these valid until we can research this more.

  • Documentation improvements and fixes:

    • type=op not needed in admin role profile.
    • Add admin role profile for Panorama.
    • Document intermediate certificate name pattern.
    • There is a single All Certificate Information (root and intermediate) in CCADB (CSV) data file now.

0.1.0 (2024-04-09)

  • fling.py, chain.py, guard.py, admin-guide.rst:

    Add --debug argument and use args.debug for all debugging related output, and be consistent in use of args.verbose for verbose output (e.g., progress messages).

  • chain.py:

    • Log when a CA certificate is not in any of Apple, Google Chrome, Microsoft, Mozilla root stores.
    • Log when 0 intermediates found for a CA certificate.

  • chain.py:

    Add message when all certificate chains were downloaded successfully.

  • chain.py:

    • Display PAN-OS certificates not in CCADB and consider them invalid, because we will not find intermediate certificate chains for these.
    • Output invalid PAN-OS certificate messages to stderr.
    • Display total invalid PAN-OS certificates found.

  • chain.py: Fix invalid path in error.

  • chain.py: Print download error to stderr.

  • chain.py: Also retry on status code 502, 504.

  • chain.py: Improve some messages.

  • chain.py:

    Since we don't use xapi.export_result 'file', check 'content' instead. There is currently an issue in pan.xapi export() where filename can be None. Fixes a bug where certificate names with parentheses were not saved to the archive.

  • chain.py: exit with status 2 when there are download failures.

  • chain.py:

    • Fix missing value for format string.
    • Change message to Error.

  • Documentation improvements and fixes.

0.0.0 (2024-03-15)

  • Initial release.
