buffer type
type
digest type - opaque
val zero : t
The zero digest
val init : unit -> ctx
Create a new context
val unsafe_update_substring : ctx -> string -> int -> int -> unit
Sha1.unsafe_update_substring ctx s ofs len updates the context
with the substring of s starting at character number ofs and
containing len characters. Unsafe: No range checking!
val update_substring : ctx -> string -> int -> int -> unit
Sha1.update_substring ctx s ofs len updates the context with the
substring of s starting at character number ofs and containing len
characters.
val update_string : ctx -> string -> unit
Sha1.update_string ctx s updates the context with s.
val update_buffer : ctx -> buf -> unit
Sha1.update_buffer ctx a updates the context with a.
Runs parallel to other threads if any exist.
val finalize : ctx -> t
Finalize the context and return digest
val copy : ctx -> ctx
Return an copy of the context
val string : string -> t
Return the digest of the given string.
val substring : string -> int -> int -> t
Sha1.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, Sha1.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, Sha1.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 file_fast : string -> t
Return the digest of the file whose name is given using fast C function
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_bin : t -> string
return a binary representation of the given digest
val to_hex : t -> string
return a printable hexadecimal representation of the given digest
