java.lang.Object | +--net.rim.device.api.crypto.PSSSignatureSigner
The PSSSignatureSigner class can sign messages using the RSA Signature
Scheme with Appendix - Probabilistic Signature Scheme RSA (PSS) signature PSS signature scheme.
We implemented PSS as per it's description in the PKCS #1 version 2.1 document.
For information on cryptographic algorithms, see Crypto Algorithms.
