Digest::SHA256::Native

Fast SHA256 computation using NativeCall to C.

Synopsis

use Digest::SHA256::Native;

say sha256-hex("The quick brown fox jumps over the lazy dog");
say sha256-hex("The quick brown fox jumps over the lazy dog".encode);
say sha256("The quick brown fox jumps over the lazy dog")».fmt('%02x').join;

Description

sha256-hex accepts a string or bytes (a Buf or Blob) and returns a hex string.

sha256 converts the hex into binary (i.e. it returns a Blob).

Examples

From https://en.wikipedia.org/wiki/Hash-based_message_authentication_code#Examples:

use Digest::HMAC;
use Digest::SHA256::Native;

say hmac-hex("key","The quick brown fox jumps over the lazy dog",&sha256);
