java.lang.Object | +--net.rim.device.api.crypto.X931SignatureVerifier
Represents the X931 signature verifier. This Signature verifier is defined in the ANSI X9.31 standard.
Note : Currently the only digests defined for use with this signature signer are SHA-1, SHA-256, SHA-384, SHA-512 and RIPEMD160. These are the only digests you can use with this class.
