HMAC SHA-1 to Match RFC 2022 Test Vectors

See more Encryption Examples

Demonstrates using Chilkat in _LANGUAGE_ to computer HMAC SHA-1 message authentication codes to match the test vectors given by RFC 2202. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const crypt = try chilkat.Crypt2.init();
    defer crypt.deinit();

    // The output will be Hex, so set the EncodingMode:
    crypt.setEncodingMode("hex");

    // Set the hash algorithm:
    // Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
    crypt.setHashAlgorithm("sha-1");
    crypt.setMacAlgorithm("hmac");

    var mac: [:0]const u8 = "";

    // Set the HMAC key:
    crypt.setMacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b", "hex") catch {};
    mac = try crypt.macStringENC(alloc, "Hi There");
    std.debug.print("{s}\n", .{mac});

    crypt.setMacKeyEncoded("Jefe", "ansi") catch {};
    mac = try crypt.macStringENC(alloc, "what do ya want for nothing?");
    std.debug.print("{s}\n", .{mac});
