Answers to Questions

How to encrypt using SHA1?

Encryption calculates a numeric footprint of 40 hexadecimal characters. The algorithm uses non linear functions, here are the 3 main ones:

$$ C(x,y,z) = (x \wedge y) \vee (\lnot x \wedge z) $$

$$ P(x,y,z) = x \oplus y \oplus z $$

$$ M(x,y,z) = (x \wedge y) \vee (x \wedge z) $$

How to decrypt SHA1 cipher?

As ciphering is based on hashing, so non linear functions, there are no simple deciphering methods.

dCode uses its own databases (2 billions potential passwords) in order to accelerate the data processing.

How to recognize SHA-1 ciphered text?

The hash is composed of 40 hexadecimal characters 0123456789abcdef.

What are the variants of the SHA-1 cipher?

The database search can be complicated by inserting salt to the word (a prefix or a suffix, or both).

SHA1(dCode) = 15fc6eed5ed024bfb86c4130f998dde437f528ee but SHA1(dCodeSUFFIX) = 9b63fcb31388acee8879018244a3d107033890f1

Another variant is DOUBLE SHA1, that consists in applying SHA1 twice.

SHA1(dCode) = 15fc6eed5ed024bfb86c4130f998dde437f528ee but SHA1(SHA1(dCode)) = cb8687909e03bb4b3b8d687de973d2668bed52a8

What does SHA1 means?

SHA1 stands for Secure Hash Algorithm

When SHA1 have been invented ?

By the National Security Agency in 1995
