sha512-file

Arguments: filespec &key return

Using sha512-init, sha512-update, and sha512-final, compute the SHA512 hash on the contents of the file given by filespec. Returns the value of sha512-final on the implicitly created context. The return argument is passed to sha512-final (where the various possible values are discussed). Note the warning about integer returns perhaps losing leading 0's.
