Sha512.unsafe_update_substring ctx s ofs len updates the context with the substring of s starting at character number ofs and containing len characters. Unsafe: No range checking!
Sha512.update_substring ctx s ofs len updates the context with the substring of s starting at character number ofs and containing len characters.
Sha512.update_string ctx s updates the context with s.
Sha512.update_buffer ctx a updates the context with a. Runs parallel to other threads if any exist.
Sha512.substring s ofs len returns the digest of the substring of s starting at character number ofs and containing len characters.
If len is nonnegative, Sha512.channel ic len reads len characters from channel ic and returns their digest, or raises End_of_file if end-of-file is reached before len characters are read. If len is negative, Sha512.channel ic len reads all characters from ic until end-of-file is reached and return their digest.
