About this tool

Why decryption can "fail"

If decryption fails, the cause is almost always one of: wrong password, ciphertext corrupted in transit (line breaks introduced, padding stripped), or the ciphertext came from a different tool with a different format. Our tool expects ciphertext produced by the matching Text Encrypter on this site.
