Indicates whether this DH
instance has a private key associated with it or not. The private key may be retrieved with DH#priv_key.
Verifies whether the signature is valid given the message digest input. It does so by validating sig
using the public key of this DSA
instance.
Deprecated in version 3.0. Consider using PKey::PKey#sign_raw
and PKey::PKey#verify_raw
instead.
digest
A message digest of the original input data to be signed.
sig
A DSA signature value.
Indicates whether this DSA
instance has a private key associated with it or not. The private key may be retrieved with DSA#private_key.
Returns whether this EC
instance has a private key. The private key (BN
) can be retrieved with EC#private_key
.
Does this keypair contain a private key?
The list of cipher suites configured for this context.
Sets the list of available cipher suites for this context. Note in a server context some ciphers require the appropriate certificates. For example, an RSA cipher suite can only be chosen when an RSA certificate is available.
