encrypt static method
Encrypts a private key
Implementation

}
KeyIV keyInfo = KDF.pascalCoin(password, salt: salt);
Uint8List privateKeyEncrypted = AesCbcPkcs7.encrypt(privateKeyEncoded,
key: keyInfo.key, iv: keyInfo.iv);
return PDUtil.concat(
[PDUtil.stringToBytesUtf8("Salted__"), salt, privateKeyEncrypted]);
