Documentation

       Module BLAKE512
        : S

       BLAKE512  is  the  BLAKE2b  hash  function  producing 512-bit (64-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.
