Is there any place i can learn some codes to conceal messeges and how to decode them?

College might be a good place to start.

Or google "Cryptology"

To save you the trouble of wading through thousands of sites on the subject, here's a simple one.

Use a shift cypher, meaning you just shift the letters of the coded message a fixed number of places against the original, or decoded, text.

Example, a shift of three places to the right:


The word "help" would become "LHOS". You could work out a system with the person you're sending the message to so they'll know the key. Try using the day of the month, and assign Right to Odd Numbered days and Left to Even numbered days. Today, June 28 would be a Left Shift of 28 spaces.

Be warned, this cypher is very easy for any novice cryptologist to crack, but unless you are significantly concerned about someone monitoring your communications and have reason to believe they will intercept them, it should be fine for you.

Is it prudent to ask why you need such encryption?

Or is that too inquisitive?

I'm not the FBI or CIA.

I promise
