How to store Password in a file by using efficient algorithm other than ROT by N?

[Project Support]

"I saw 'ROT by N' algorithm by Mike. Still i want an efficient and high security algorithm for storing data in a file. Thanks in Advance"

An algorithm I generally use converts each character to its ASCII code, then inverts the ASCII code bitwise and finally converts the ASCII code back to a character.

I don't know how secure the algorithm is considered.
If needed, it would be very easy to add a constant or even computed value (eg offset of character in the string...) to each ASCII code to increase the security level.

Hi;

Two techniques are: hashing and encryption. Without knowing requirements, my first inclination is usually hashing. Because of the nature of hashing, you may need to take a closer look at the recovery procedures.

Thanks JB. The algorithm is very simple. I can modify this to my secure application.
