HMAC with SHA256

See more Encryption Examples

Demonstrates how to compute a HMAC SHA256 keyed-hash message authentication code. 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("sha256");
    crypt.setMacAlgorithm("hmac");

    // Set the HMAC key:
    crypt.setMacKeyEncoded("The_API_Secret", "ascii") catch {};
    const mac = try crypt.macStringENC(alloc, "The quick brown fox jumps over the lazy dog");
    std.debug.print("{s}\n", .{mac});
