This implementation goes beyond the basic single-key model to use multiple keys in a particular sequence, making it that much more difficult to brute-force. This implementation goes beyond the basic single-key model to use multiple keys in a particular sequence, making it that much more difficult to brute-force.
In these examples, I'm encrypting the same string with the same keys in order to keep consistency with the output, and to demonstrate that an encrypted string from a C program will be decryptable in a Java application, etc. In these examples, I'm encrypting the same string with the same keys in order to keep consistency with the output, and to demonstrate that an encrypted string from a C program can be decrypted in a Java application, or any combination, so long as the keys remain the same.
