Hi I'm new here and am new to javascript as well.
I'm wondering that, as I've made myself a code for the english alphabets (like a becomes h, b becomes r, c becomes t...), can javascript help me encrypt and decrypt, like putting a little tool on my webpage?
Please help. Thanks a lot!

Though unless someone here decides to write the entire program for you, you'll have to make your question a little more specific.

BTW, I hope you don't plan on using the form of encryption you speak of for any kind of real security. Simple substitution ciphers are the simplest form of encryption, and thus the simplest to break.
