Module Digest
: (module Stdlib__digest)
type t = string
The type of digests: 16-character strings.
val compare : t -> t -> int
The comparison function for 16-character digest, with the same specification as compare and the
implementation shared with String.compare . Along with the type t , this function compare allows the
module Digest to be passed as argument to the functors Set.Make and Map.Make .
Since 4.00.0
val equal : t -> t -> bool
The equal function for 16-character digest.
Since 4.03.0
val string : string -> t
Return the digest of the given string.
val bytes : bytes -> t
Return the digest of the given byte sequence.
Since 4.02.0
val substring : string -> int -> int -> t
Digest.substring s ofs len returns the digest of the substring of s starting at index ofs and containing
len characters.
val subbytes : bytes -> int -> int -> t
Digest.subbytes s ofs len returns the digest of the subsequence of s starting at index ofs and containing
len bytes.
Since 4.02.0
val channel : 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 : out_channel -> t -> unit
Write a digest on the given output channel.
val input : 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. Raise Invalid_argument if the
argument is not exactly 16 bytes.
val from_hex : string -> t
Convert a hexadecimal representation back into the corresponding digest. Raise Invalid_argument if the
argument is not exactly 32 hexadecimal characters.
Since 4.00.0
