Questions
Common questions
- Do I need an account?
- No. Open a tool and use it.
- Which tool do I use to decode a message?
- The cipher solver. Paste the message, pick a cipher, and read the result. If you do not know the cipher, start with the Caesar shift list, then look at the letter frequencies.
- Which tool do I use to check a photo before I share it?
- The photo metadata viewer. It shows whether the photo carries its location, and it makes a copy without that data.
