- ssh_pki_import_cert_base64()
- ssh_pki_import_cert_file()
- ssh_pki_import_cert_blob()
Those functions are currently simple wrappers around their pubkey counterpart.
- ssh_pki_copy_cert_to_privkey()
This function copies the cert-specific data to a private key.

Per ecdsa(3ssl), ECDSA_SIG_new does allocate its 'r' and 's' bignum fields.
Fix a bug where the initial 'r' and 's' bignums were being overwritten with
newly-allocated bignums, resulting in a memory leak.

Ensure to honor the 'first_kex_packet_follow' field when processing
KEXINIT messages in the 'ssh_packet_kexinit' callback. Until now
libssh would assume that this field is always unset (zero). But
some clients may set this (dropbear at or beyond version 2013.57),
and it needs to be included when computing the session ID.
Also include logic for handling wrongly-guessed key exchange algorithms.
Save whether a client's guess is wrong in a new field in the session
struct: when set, the next KEX_DHINIT message to be processed will be
ignored per RFC 4253, 7.1.
While here, update both 'ssh_packet_kexinit' and 'make_sessionid' to
use softabs with a 4 space indent level throughout, and also convert
various error-checking to store intermediate values into an explicit
'rc'.
Patch adjusted from original to ensure that client tests remain passing
(ie 'torture_connect'): restrict the changes in 'ssh_packet_kexinit'
only for the 'server_kex' case.

Enable retrieving the "ecdsa-sha2-nistpNNN" name of ECDSA keys with a
new 'ssh_pki_key_ecdsa_name' API. This gives more information than the
'ssh_key_type_to_char' API, which yields "ssh-ecdsa" for ECDSA keys.
The motivation is that this info is useful to have in a server context.
The torture_pki unit test is updated to include the new API, and a few
more passes are added to additionally test 384 and 521-bit keys.
