I need a piece of code that defines functions which can encrypt and decrypt a piece of string. What I basically want is that the string should not be visible to third-party users, so that when the string originates in one file, it is converted to, say, an integer value using the encrypt function and then it is passed as parameter to another file. There the decrpyt function then decrypts it back and uses the string to perform actions on it.
Any suggestions or already available codes will be just fine!
Please help me out. Thanks!
Install tcllib. There are several standard encryption algorithms implemented in tcllib.
The following encryption algorithms are available:
