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?
Iterate over each node in the tree. Yields each node to block depth first.
Save session state to the session’s FileStore file.
Save session state to the session’s PStore file.
Returns true if files may be created in the directory by STOU, STOR, APPE, and RNTO.
Returns true if the file or directory may be renamed by RNFR.
