We need generate an algorithm that allow us obtain anyone of the 3 values (plaintext, ciphertext or key) with the other two values. BUT: -The plaintext is an ascii -The ciphertext always is a base64 (one line) -The key is no more than 24 bytes. We don't need a hard encoding, the goal is a short key. Attached you can find an html that explain the functions that we request.

Dear client, how are you? Checked your post. But your requirement is yet somewhat not clear for me. 1) Why you need Matlab & Mathematica skill for this task? 2) What program you want? HTML/JavaScript or executable file(EXE)? 3) And your requirement on Encryption/Decryption is not that clear. Seems your task is no problem. But needs more details. Please check my "Profile & Work List" and tell me details if my skill is in your concern. Looking forward to your response. Thanks.
