It encrypts and decrypts with the same function (I forget the technical term for it ...)

Symmetrical cipher. Also (though this doesn't matter in this particular case), RC4 is a stream cipher, which means it encrypts a character at a time. This is as opposed to a block cipher, which encrypts a small block of characters (usually 8 characters, in my experience) at once.
