    Question how to encrypt/decrypt

    I need to encrypt/decrypt a set of numbers such as '1234'. The next stept to encrypting this number set is to ad '7' to each of the charaters ex = 1(becomes 8), 2(becomes 9), 3(becomes 0) and 4(becomes 1). Now, the addition part isn't causing me headaches yet, but how to pull the 1, 2,3, & the 4 out and add the 7 to them. Can someone show me how this works. Without running the code, it took me all of 15 seconds to realize that 1234 + 7777 wasn't what I wanted.

    Thanks
