Get Base64 Public Key from Private Key

See more ECC Examples

Demonstrates how to get the public key in base64 format from a private key. Swift

func chilkatTest() {
    var success: Bool = false

    // Load a private key from base64.
    let bd = CkoBinData()!
    success = bd.appendEncoded(encData: "MHQCA....n0Q==", encoding: "base64")

    let privKey = CkoPrivateKey()!
    success = privKey.loadAnyFormat(privKeyData: bd, password: "")
    if success == false {
        print("\(privKey.lastErrorText!)")
        return
    }

    let pubKey = CkoPublicKey()!
    privKey.toPublicKey(pubKey: pubKey)

    var pubKeyBase64: String? = pubKey.getEncoded(preferPkcs1: true, encoding: "base64")
    print("\(pubKeyBase64!)")
