HMAC with SHA256

See more Encryption Examples

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

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

    let crypt = CkoCrypt2()!

    // The output will be Hex, so set the EncodingMode:
    crypt.encodingMode = "hex"

    // Set the hash algorithm:
    // Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
    crypt.hashAlgorithm = "sha256"
    crypt.macAlgorithm = "hmac"

    var mac: String?

    // Set the HMAC key:
    crypt.setMacKeyEncoded(key: "The_API_Secret", encoding: "ascii")
    mac = crypt.macStringENC(inText: "The quick brown fox jumps over the lazy dog")
    print("\(mac!)")
