I am not familiar at all with string encryption and decryption.
I have the following function:
void encrypt (char e[] )
{
for( int i=0; e[i] != '\0'; ++i )
{
++e[i];
}
}
void decrypt( char * ePtr )
{
for( ; * ePtr != '\0'; ++ ePtr )
{
--(* ePtr);
}
}
It's obviously completely pathetic.
Anyone care to improve this? Something that can boast of industry standard would be excellent.

What is it needed for? If you're releasing a binary people can just copy and paste the ASM for the encryption and decryption functions or hook them and have the output for them get logged to a console window.

If your just doing ascii encryption keep in mind that it's from 0 - 127. So if you exceed 127 you'll have to loop it down to 0. If you drop under 0 you have to loop it back around to 127. Otherwise when you save it you'll be left with nothing useful.
However, as danpaul88 said, Google is an excellent place to check out too, you can go and get any encryption algorithm off of there in open source pretty much (wiki usually has source with examples of the algorithms as well).
