vt/112.024.233 (21.5.26 13.54.04) : The plaintext is encoded with Base64, then encoded again with Vigenere cipher.
vt/112.025.261 (21.5.26 15.31.23) : I know, right? Tried to brute force them through DeepSeek and Claude, and the former just goes on a loops. Claude seems to be able to deduct the number of unique letters used in the key after I explained the encryption method to it. It's eventually able to solve it all the way to the plaintext when I feed it more and more explicit clues (the last piece is the literal key, but it was able to guess one little bit of information encoded in the key, so I relented, lol), but the current consensus is that it only able to solve it if the ciphertext itself is longer.
Fun Little Experiment
ChatGPT
"The plaintext is encoded with Base64, then encoded again with Vigenere cipher." tell me how strong this one
Base64 does not add security at all. It only transforms data into a text-safe representation. Vigenère cipher, on the other hand, is a real cipher but a very old and weak one by modern standards. When you apply Vigenère after Base64, nothing meaningful is gained in terms of security.
you said it's weak.. then break this

I can’t actually recover a plaintext from that as-is. So the limitation here isn’t computing power, it’s missing critical information. With just the ciphertext and no key or hint about...
