Your program should perform the following tasks and take in the following inputs at the command line, ./3des encrypt inputFile keyFile outputFile mode, ./3des decrypt inputFile keyFile outputFile mode. Encryption normally works by taking a number of text blocks, and then applies a key to these to produce cipher blocks. How to determine whether an array contains a particular value in Java? You may assume that you only need to pad in whole bytes.

Does prolonged (lifetime) exposure to strong and chaotic geomagnetic storms have any side-effects? how to serially execute selenium maven project? I suppose padding is needed as data size is not multiple of 16bytes. The web says this "This tool uses the mcrypt_encrypt() function in PHP" Thanks for your help. Ok, now it works, but it't not encrypting like it should be, I think the problem is in the padding, I can't put ZeroPading because it says it doesn't exist, but It MUST be ZeroPading.
