Module `Sha256`Source

SHA256 OCaml binding

Sourcetype ctx

Context type - opaque.

type buf =
  (int, Stdlib.Bigarray.int8_unsigned_elt, Stdlib.Bigarray.c_layout)
    Stdlib.Bigarray.Array1.t

Buffer type.

Sourcetype t

Digest type - opaque.

Sourceval zero : Sha256.t

The zero digest.

Sourceval init : unit -> Sha256.ctx

Create a new context.

Sourceval unsafe_update_substring : Sha256.ctx -> string -> int -> int -> unit

Sha256.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!

Sourceval update_substring : Sha256.ctx -> string -> int -> int -> unit

Sha256.update_substring ctx s ofs len updates the context with the substring of s starting at character number ofs and containing len characters.

Sourceval update_string : Sha256.ctx -> string -> unit

Sha256.update_string ctx s updates the context with s.

Sourceval update_buffer : Sha256.ctx -> Sha256.buf -> unit

Sha256.update_buffer ctx a updates the context with a. Runs parallel to other threads if any exist.

Sourceval finalize : Sha256.ctx -> Sha256.t

Finalize the context and return digest.

Sourceval copy : Sha256.ctx -> Sha256.ctx

Return a copy of the context.

Sourceval string : string -> Sha256.t

Return the digest of the given string.

Sourceval substring : string -> int -> int -> Sha256.t

Sha256.substring s ofs len returns the digest of the substring of s starting at character number ofs and containing len characters.

Sourceval buffer : Sha256.buf -> Sha256.t

Return the digest of the given buffer.

Sourceval channel : Stdlib.in_channel -> int -> Sha256.t

If len is nonnegative, Sha256.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, Sha256.channel ic len reads all characters from ic until end-of-file is reached and return their digest.

Sourceval file : string -> Sha256.t

Return the digest of the file whose name is given.

Sourceval file_fast : string -> Sha256.t

Return the digest of the file whose name is given using fast C function.

Sourceval output : Stdlib.out_channel -> Sha256.t -> unit

Write a digest on the given output channel.

Sourceval input : Stdlib.in_channel -> Sha256.t

Read a digest from the given input channel.

Sourceval to_bin : Sha256.t -> string

Return a binary representation of the given digest.

Sourceval to_hex : Sha256.t -> string

Return a printable hexadecimal representation of the given digest.

Sourceval equal : Sha256.t -> Sha256.t -> bool

Returns whether two hashes are equal.

Sourceval of_bin : bytes -> Sha256.t

Sha256.of_bin digest converts the binary representation of a digest to the internal representation of Sha256.t.

Sourceval of_hex : string -> Sha256.t

Sha256.of_hex digest converts the hexadecimal representation of a digest to the internal representation of Sha256.t.
