Golang : Padding data for encryption and un-padding data for decryption
Continuing from our last tutorial on TripleDES encryption. We purposely left out the padding/un-padding functions to keep the tutorial as simple as possible for reader to understand. In this tutorial we will elaborate more on the need for padding the input plaintext data before encryption. For crypto algorithms that operate on blocks of data such as those in cipher-block chaining (CBC) mode. We ha
