Sep 13, 2012 · SHA-256 is one of the three algorithms in the SHA2: specification. The others, SHA-384 and SHA-512, are not: offered in this implementation.

and the exception is thrown at the line where rsa.SignData() is called. This is NOT using X509 certificates, it is not a duplicate. BTW see answer below. Apr 21, 2014 · SHA256 and SHA512 both use the same algorithm, while process the data in different sized chunks. SHA256 uses 32 bit blocks and SHA512 uses 64 bit blocks. SHA1 is close to MD5 with some concerns about the uniqueness of the resulting hashes and thus, it is not approved for many cryptographic uses since 2010.

The following program shows how to generate SHA256 hash in Java. This program uses the built-in class java.security.MessageDigest for creating the SHA256 hash. Note that the hash output generated is binary data and hence if you try to convert it directly to String, you will get unprintable weird looking characters.
