mod_nss support

[jturnsek]

Great project. Can it be used for mod_nss integration?

[irtimmer]

Currently only the functions required by OpenSSH are implemented. Unless mod_nss uses the same subset of functions it probably won't work. Notice a TPM is designed for mass signing. It can took a second for signing is therefore not very usable for securing private keys of servers. Unless there are a very small number of users and the agreed session key is cached for new connections.
