Hello all,
Got a bit of the programming "bug" going on, and was just curious as to how difficult it would be to write an encryption/decryption program. I wasn't planning on anything too difficult; my main aim was focusing on - and learning to understand - the encryption process itself, rather than how it functions within larger applications.
Something basic like the user inputting a string, the string being converted into cipher text and output to file. Then, giving the user the option to reload the file and running a decryption algorithm, so that their original string can be viewed in tact.
Basically, my question is, do I go about devising the encryption/decryption algorithm myself, as I wouldn't have thought these methods would be divulged, because that'd sort of defeat the object of encryption.
Let me just clarify, I'm NOT asking for someone to do the algorithm for me, because I quite like the challenge of trying to implement it myself. However, I just wanted to hear the opinions of you guys, as my knowledge in this area is limited.
Thanks all.
