X509Certificate GetCertHash SHA256

See more Certificates Examples

Shows how to get the SHA256 hash of a certificate. Swift

func chilkatTest() {
    var success: Bool = false

    let cert = CkoCert()!

    // Load a certificate object with a certificate.
    // The certificate object could have come from any source,
    // or perhaps was obtained from another Chilkat function.
    // The source does not matter.  What matters is that we have
    // a cert object loaded with the certificate..
    success = cert.load(fromFile: "qa_data/certs/cert_test123.cer")
    if success != true {
        print("\(cert.lastErrorText!)")
        return
    }

    // Get the binary DER of the certificae, and compute the SHA256 hash:
    let bdDer = CkoBinData()!
    cert.exportDerBd(cerData: bdDer)

    // Get the base64 representation of the SHA256 hash.
    var certHash: String? = bdDer.getHash(algorithm: "sha256", encoding: "base64")

    print("Certificate hash in base64 = \(certHash!)")
