How does it work?
SHA1 means a 160-bit encryption algorithm, generating a 40-character hexadecimal hash, whatever the captcha.
This algorithm is not reversible, ie it’s normally impossible to find the original word from the sha1 hash. Our tool uses a huge database in order to have the best chance possible to trace the captcha.
Just enter a SHA1 hash in the form above to try to decrypt!
