public class RSAPSSSignature extends BaseSignature
The RSA-PSS signature scheme is a public-key encryption scheme combining the RSA algorithm with the Probabilistic Signature Scheme (PSS) encoding method.
The inventors of RSA are Ronald L. Rivest, Adi Shamir, and Leonard Adleman, while the inventors of the PSS encoding method are Mihir Bellare and Phillip Rogaway. During efforts to adopt RSA-PSS into the P1363a standards effort, certain adaptations to the original version of RSA-PSS were made by Mihir Bellare and Phillip Rogaway and also by Burt Kaliski (the editor of IEEE P1363a) to facilitate implementation and integration into existing protocols.

Constructs an instance of this object using the designated message digest algorithm as its underlying hash function, and having 0-octet salt.
Parameters: mdName the canonical name of the underlying hash function.
Constructs an instance of this object using the designated message digest algorithm as its underlying hash function.
Parameters: mdName the canonical name of the underlying hash function. sLen the desired length in octets of the salt to use for encoding / decoding signatures.
