HMAC with SHA256

See more Encryption Examples

Demonstrates how to compute a HMAC SHA256 keyed-hash message authentication code. Rust

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

let crypt = chilkat::Crypt2::new();

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

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

// Set the HMAC key:
let _ = crypt.set_mac_key_encoded("The_API_Secret", "ascii");
let mac = crypt.mac_string_enc("The quick brown fox jumps over the lazy dog").unwrap_or_default();
println!("{}", mac);
