Even if your encyption method get working, you're decryption method is not going to work. Indeed you are encrypting using Base64 followed bye AES. And you decrypt the whole thing using Base64 followed by AES. I am almost sure that this two type of encryption are not exchangeables. (you...

We will be using the class"CL_SEC_SXML_WRITER"for encryption and decryption process. The class "CL_SEC_SXML_WRITER" contains 3 algorithm for encryption and decryption. Below are the details. AES Algorithm 128 Bit AES Algorithm 192 Bit ...
To facilitate the encryption and decryption process, you need to use a secret encryption key. This key is much like the one you’d use to open your car, or the door to your house. Encryption keys come in two flavors: Symmetric keys ...
Multiplication in GF(28) is trickier, however. As you'll see later in the C# implementation, the AES encryption and decryption routines need to know how to multiply by only the seven constants 0x01, 0x02, 0x03, 0x09, 0x0b, 0x0d, and 0x0e. So instead of explaining GF(28) multipli...
As mentioned DES is symmetric and requires the same key for encryption as decryption. That key needs to be the right number of bits for the cipher that you're using. For DES that's 56-bit. Before you go too far with that though, here are a few things you might want to consider...
