CryptoProviderpublic final class CryptoProvider extends Provider Implementation of Provider for SecureRandom, MessageDigest and Signature
using a Secure Hash Algorithm, SHA-1;
see SECURE HASH STANDARD, FIPS PUB 180-1 (http://www.itl.nist.gov/fipspubs/fip180-1.htm)
The implementation supports "SHA1PRNG", "SHA-1" and "SHA1withDSA" algorithms described in
