void _libssh2_rsa_free(libssh2_rsa_ctx *rsactx);
Releases the RSA computation context at rsactx.

#define as 1 if the crypto library supports RSA SHA2 256/512, else 0.
If defined as 0, the rest of this section can be omitted.

const unsigned char *hash,
size_t hash_len,
unsigned char **signature,
size_t *signature_len);
RSA signs the (hash, hashlen) SHA-2 hash bytes based on hash length and stores
the allocated signature at (signature, signature_len).
Signature buffer must be allocated from the given session.
Returns 0 if OK, else -1.
This procedure is already prototyped in crypto.h.

int _libssh2_rsa_sha2_verify(libssh2_rsa_ctx * rsa,
size_t hash_len,
const unsigned char *sig,
unsigned long sig_len,
const unsigned char *m, unsigned long m_len);
Verify (sig, sig_len) signature of (m, m_len) using an SHA-2 hash based on
hash length and the RSA context.
Return 0 if OK, else -1.
This procedure is already prototyped in crypto.h.
