How to obtain the original string? #16

Closed flacidsnake closed 6 years ago

flacidsnake commented 6 years ago

Hi, the library works pretty well hashing strings, but, how can I do the reverse process? I mean, obtain the original string using the key and the hash.

Regards.

P.S.: Thank you for adding the license!

Hash functions are one way functions. It's not encryption decryption algorithm. You only hash on server and rehash in client to check the validity of the data. If you want encryption decryption algorithms check my other repos.

Thank you for your fast reply! I'll check your AES library.

No problem
