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

31       The type of digests: 16-character strings.

36       val string : string -> t
37
38       Return the digest of the given string.

43       val substring : string -> int -> int -> t
44
45
46       Digest.substring s ofs len returns the digest of  the  substring  of  s
47       starting at character number ofs and containing len characters.

52       val channel : Pervasives.in_channel -> int -> t
53
54       If  len is nonnegative, Digest.channel ic len reads len characters from
55       channel  ic  and  returns  their  digest,  or  raises  End_of_file   if
56       end-of-file is reached before len characters are read.  If len is nega‐
57       tive,  Digest.channel  ic  len  reads  all  characters  from  ic  until
58       end-of-file is reached and return their digest.

63       val file : string -> t
64
65       Return the digest of the file whose name is given.

70       val output : Pervasives.out_channel -> t -> unit
71
72       Write a digest on the given output channel.
73
74
75
76
77       val input : Pervasives.in_channel -> t
78
79       Read a digest from the given input channel.

84       val to_hex : t -> string
85
86       Return the printable hexadecimal representation of the given digest.
