can we assume that same encryption key is used to encrypt data if encrypted data are same? For example, plain text is 'This is sample'. First time we use 3DES algorithm and encryption key to encrypt it. Encrypted data became 'MNBVCXZ'. Second time again, we use 3DES algorithm and encryption key to encrypt it. Encrypted data became 'MNBVCXZ'. Thus, 1. Can i assume static encryption key is used in this encryption process? 2. How many keys can be used to encrypt data using 3DES algorithm?
