Removes a possibility from ‘self` @return [PossibilityState] a state with a single possibility,
the possibility that was removed from `self`
Creates an OpenSSL::OCSP::Response from status and basic_response.
Creates a new DH instance from scratch by generating the private and public components alike.
size is an integer representing the desired key size. Keys smaller than 1024 bits should be considered insecure.
generator is a small number > 1, typically 2 or 5.
Indicates whether this DH instance has a private key associated with it or not. The private key may be retrieved with DH#priv_key.
Creates a new DSA instance by generating a private/public key pair from scratch.
size is an integer representing the desired key size.
Indicates whether this DSA instance has a private key associated with it or not. The private key may be retrieved with DSA#private_key.
Creates a new EC instance with a new random private and public key.
Returns whether this EC instance has a private key. The private key (BN) can be retrieved with EC#private_key.
Generates an RSA keypair. size is an integer representing the desired key size. Keys smaller than 1024 should be considered insecure. exponent is an odd number normally 3, 17, or 65537.
Does this keypair contain a private key?
Returns true if the APPE command may be applied to the file.
Returns true if the file or directory may be deleted by DELE/RMD.
Returns true if the listing commands, LIST, NLST, and MLSD are applied to the directory.
Returns true if the RETR command may be applied to the file.
