The Firewall. The system will then process and reveal the text-based password. For security reasons, our system will not track or save any passwords decoded. Back in late , a non-Cisco source had released a program that was able to decrypt user passwords and other type of passwords in Cisco configuration files. This new program was a major headache for Cisco since most users were relying on Cisco's equipment for their repulation of strong encryption and security capabilities.

SHA-1 hash is a footprint of 40 characters hexadecimal which is made to identify the initial data and guarantee its integrity, that is useful in cryptography. SHA-1 - dCode. A suggestion?

Thank you! Encryption calculates a numeric footprint of 40 hexadecimal characters. The algorithm uses non linear functions, here are the 3 main ones:. Example: dCode is crypted with the footprint 15fc6eed5edbfb86cfddefee.
As encryption is a hashing based on nonlinear functions, there is no decryption method. This means that to retrieve the password corresponding to a sha-1 hash , there is no choice but to try all possible passwords! Technically, this operation would take several thousand years, even on the most powerful computers in the world.
However, the list of passwords used in real life is more restricted, and it becomes possible to precalculate the most likely fingerprints. However, if the password is rare, or combined with salting, it will probably not be found. The hash is composed of 40 hexadecimal characters among abcdef. The database search can be complicated by inserting salt to the word a prefix or a suffix, or both.
Indeed, if it is already difficult but possible to precalculate the fingerprints of all the words, it becomes even more difficult to precalculate with all possible prefixes and suffixes. A rainbow table is a database of words with all the pre-computed hashes and stored in order to accelerate and be able to parallelize the calculations of fingerprints.
