}
Returns the block length of the digest algorithm, i.e. the length in bytes of an individual block. Most modern algorithms partition a message to be digested into a sequence of fix-sized blocks that are processed consecutively.

digest = OpenSSL::Digest.new('SHA1') puts digest.block_length # => 64
