Show HN: Txtl – Fast static website of text utilities
I have Cyberchef locally, just unzip it and run. It has an auto function that I only manage to get working by mistake. So as is said above just learn that instead.

CyberChef from GCHQ: The Cyber Swiss Army Knife
I also discovered Ciphey. Neat little tool indeed, but it's being deprecated. It's mentioned in this issue[1] and being replaced with Ares[2]. Neither could decipher this strange encryption[3] I used it on :(

tools for decrypting
if you're looking for something that would decrypt most well-known encodings/ciphers, there's ciphey. but no such thing exists to decrypt every known file type because, if it did, everyone would be using it.
