WebThe following generation of SHA functions with much larger message digest sizes, namely 256, 384, and 512 bits, was introduced in 2000 and adopted as a FIPS standard in 2002 as well as an ISO standard in 2003 . The latest member of the family, namely SHA-224, was adopted in a Change Notice to FIPS 180-2 in 2004.

Your RSA key is 1024 or 2048 bits, and the block size when using it as a cipher is the same. Since both hashes are smaller than the RSA block size, they need to be padded out to that size. grain high tea
