Sha512() Encrypt & Decrypt

About Sha512 :

Sha-512 is a function of cryptographic algorithm Sha-2, which is an evolution of famous Sha-1. Sha-512 is very close to its "brother" Sha-256 except that it used 1024 bits "blocks", and accept as input a 2^128 bits maximum length string. Sha-512 also has others algorithmic modifications in comparison with Sha-256. This cryptographic function is part of the U.S Federal Information Processing Standard. This website and its pertinent database allows you to decrypt, if you're lucky, your sha512 hashes and find back the plaintexts. Our decryption database contains more than 1.000.000.000 hashes coming from all the wordlists I was able to find on the internet.I then created a script to enlarge this wordlist by switching letters, numbers, etc...to obtain an unique and pertinent database which will help you to decrypt your hashes.
Sha-512 is very secure, but also takes a lot of database space. If you want to use it, you should still use a salt to improve security. A salt is a string sequence that you add to the user's password to add special characters to it, and makes it longer. This will help by making bruteforce more difficult, and avoid the password to be found on an online database.
