Export Private Keys from Java KeyStore to JWK Set

See more Java KeyStore (JKS) Examples

Demonstrates how to export the private keys from a Java KeyStore to a JWK Set. Each private key alias is exported to the "kid" parameter.

Note: This example requires Chilkat v9.5.0.66 or greater.

Swift

func chilkatTest() {
    var success: Bool = false

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

    // Note: This example requires Chilkat v9.5.0.66 or greater.

    let jks = CkoJavaKeyStore()!

    var jksPassword: String? = "secret"

    // Load the Java keystore from a file.  The JKS file password is used
    // to verify the keyed digest that is found at the very end of the keystore.
    // It verifies that the keystore has not been modified.
    success = jks.loadFile(password: jksPassword, path: "qa_data/jks/test_secret.jks")
    if success != true {
        print("\(jks.lastErrorText!)")
        return
    }

    // Export to JWK Set format.
    // (Exports the compact 1-line JSON string to a StringBuilder..)
    let sbJwkSet = CkoStringBuilder()!
    success = jks.toJwkSet(password: jksPassword, sbJwkSet: sbJwkSet)
    if success != true {
        print("\(jks.lastErrorText!)")
        return
    }

    // To get in human-readable format, load into a JSON object and emit non-compact.
    let json = CkoJsonObject()!
    json.loadSb(sb: sbJwkSet)
    json.emitCompact = false
    print("\(json.emit()!)")
