Support for certificate based authentication

[rakesh babu <chinnirakesh.babu@xxxxxxxxx>]

Hello Everyone,

I Am trying to integrate libssh with netconf. (both at client & server)

As part of the integration, I came across 'public-key' authentication.
Also, I found more articles that recommend using certificates over actual
keys which is because of ease of use and more control over key-management,
expiration, etc.

Found below available APIs from source code:
Support to load certificate is available in *pki_import_cert_buffer*.
(pki.c)
Support to load public-key and private key is available. (pki.c)

Gone through the examples available in 'libssh/libssh-0.9/examples', but
couldn't find callbacks to achieve certificate based login,
- Loading CA certificate on the client-side to authenticate the server
certificate.
- Certificate of the client loaded at the server to authenticate the client.

Can anyone please guide me through the process to load keys/certificates to
achieve 'single sign-on' or provide any links if any.

Thanks in advance.
