whats the most sufficient way to make decryption software? What are the recoomendations for one?
sufficient for what purpose? rot13 is sufficient for some purposes. PGP is better for others.
help!! I am trying to create a program that can crack passwords, mainly because I always forget mine. How would I go about doing that? Can someone help me please?
Unix passwords cannot be "decrypted". Instead you must encrypt the plaintext and then compare it to the value stored in the password file. There are several password crackers freely available on the net which will attempt to brute-force a password.
Why don't you just pick a password that is easier to remember, or write it down somewhere safe. (Under your keyboard is not safe!) -- remember to never store your login name and password, or hostname and password in the same place.
