Frequently asked questions

Is the cipher in TLS Cipher Reference secure for real data?+

No. Classic ciphers like this are trivially broken by modern computers and exist for puzzles, CTF challenges, escape rooms and learning how cryptography evolved. For real protection, use AES or another modern algorithm.

Can TLS Cipher Reference both encode and decode?+

Yes. TLS Cipher Reference works in both directions, so you can encrypt a message and decrypt it again, or solve a coded message you were given.

Is TLS Cipher Reference free to use?+

Yes. TLS Cipher Reference is 100% free with no sign-up, no account, no usage limits and no watermarks. Use it as often as you like.

Does TLS Cipher Reference upload my data to a server?+
