Module Digestmodule Digest:
MD5 message digest.
This module provides functions to compute 128-bit ``digests'' of
arbitrary-length strings or files. The digests are of cryptographic
quality: it is very hard, given a digest, to forge a string having
that digest. The algorithm used is MD5. type t =
The type of digests: 16-character strings.
val string :
Return the digest of the given string.
val substring : Digest.substring s ofs len returns the digest of the substring
of s starting at character number ofs and containing len
characters.val channel :
If
len is nonnegative, Digest.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, Digest.channel ic len reads
all characters from ic until end-of-file is reached and return
their digest.val file :
Return the digest of the file whose name is given.
val output :
Write a digest on the given output channel.
val input :
Read a digest from the given input channel.
val to_hex :
Return the printable hexadecimal representation of the given digest.
