Digest.BLAKE256(3) OCaml library Digest.BLAKE256(3) NAME Digest.BLAKE256 - BLAKE256 is the BLAKE2b hash function producing 256-bit (32-byte) digests. Module Module Digest.BLAKE256 Documentation Module BLAKE256 : S BLAKE256 is the BLAKE2b hash function producing 256-bit (32-byte) digests. It is cryptographically secure, and the digests are large enough to thwart brute-force attacks. Since 5.2 type t = string The type of digests. val hash_length : int The length of digests, in bytes. val compare : t -> t -> int Compare two digests, with the same specification as compare . val equal : t -> t -> bool Test two digests for equality. val string : string -> t Return the digest of the given string. val bytes : bytes -> t Return the digest of the given byte sequence. val substring : string -> int -> int -> t 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 subbytes s ofs len returns the digest of the subsequence of s starting at index ofs and containing len bytes. val channel : in_channel -> int -> t Read characters from the channel and return their digest. See Digest.channel for the full specification. 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. Raises Invalid_argument if the length of the argument is not hash_length , val of_hex : string -> t Convert a hexadecimal representation back into the corresponding digest. Raises Invalid_argument if the length of the argument is not 2 * hash_length , or if the arguments contains non-hexadecimal characters. OCamldoc 2024-05-31 Digest.BLAKE256(3)
