General Cryptogrophy

Hello all! IM kinda new here, even though ive been registeres for a while. Ok, ive been browsing around here for a while, and ive seen somthing called shadow and deshadow. What is this? Are there programs that add somthing like noise to text? Well, my next post is gonna be a message, using some form of the Fibonacci sequence and hebrew. More later, hope ya'll will enjoy it!

Deshadow is a program used to decrypt a password, password file

Shadow enhances the security of system authentication files and Improves the system security by moving encrypted password hashes from the world-readable /etc/passwd file to /etc/shadow, which is readable only by the root user.

i see. Kinda like just decrypting with bits and the keyword. kewl!
