       MD5 message digest.

       This  module provides functions to compute 128-bit ``digests'' of arbitrary-length strings or files. The digests are of cryptographic qual-
       ity: it is very hard, given a digest, to forge a string having that digest. The algorithm used is MD5.

       type t = string

       The type of digests: 16-character strings.

       val string : string -> t

       Return the digest of the given string.

       val substring : string -> int -> int -> t

       Digest.substring s ofs len returns the digest of the substring of s starting at character number ofs and containing len characters.

       val channel : Pervasives.in_channel -> int -> t

       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 : string -> t

       Return the digest of the file whose name is given.

       val output : Pervasives.out_channel -> t -> unit

       Write a digest on the given output channel.

       val input : Pervasives.in_channel -> t

       Read a digest from the given input channel.

       val to_hex : t -> string

       Return the printable hexadecimal representation of the given digest.
