show you the code: Base64 UrlEncoder for query parameter the key and iv are configured in properties in base64 format. So I use Base64 Decoder decode them before create SecretKeySpec and IvParameterSpec. new SecretKeySpec(Base64.getDecoder().decode(aliasKey), "AES"), new IvParameterSpec(Base64.getDecoder().decode(aliasIv))); Since I am using AES to encrypt query parameter which will be transport via internet. so I use Base64 UrlEncoder for encrption and UrlDecoder for decryption. return Ba  

The answer is to use an embedded ldap server. spring-ldap-test bring an embedded ldap server based on ApacheDS or UnboundID. In this post, I will demo how I use UnboundID and spring-ldap-test to do testing against an embedded LDAP server. The UnboundID LDAP SDK for Java is a fast, powerful, user-friendly, and completely free Java library for communicating with LDAP directory servers. It offers better performance, better ease of use, and more features than other Java-based LDAP APIs. It is act  

In my previous post, I mentioned how to encrypt data with PGP public key. In this post, I will tell you how to decrypt the data with PGP private key. You need a PGP key pair to test the encryption and decryption and see it works. Check this post to generate the PGP key pair. Read|Load PGPPrivateKey from file don't forget the deps before you write your code. Check the encrypt post for it.
