encrypt_hex should be encrypt, decrypt_hex should be decryt about xxtea HOT 3 CLOSED

Yes, it's an incompatible change. But it is simpler than the previous ones.
If we renamed encrypt into encrypt_raw, and encrypt_hex into encrypt, it's another incompatible change.
So, maybe it is easier to change the app code, how do you think?
I know this may sound unfriendly, but sorry. And I will try to maintain backwards as possible as I can from now on.

The core method of XXTEA, btea, operates on an array of int32. After calling btea, longs2bytes is called to convert the array into binary bytes. And we need another step, hexlify, to convert binary bytes into hex representation. According to this reason, it is natural that encrpyt returns bytes, isn't it?

A good example to look at is hashlib, where digest returns bytes, and hexdigest returns hex.
Perl's [ECB](When I made this incompatible change, I was mimic Perl's [ECB]%28http://search.cpan.org/~appel/Crypt-ECB-1.40/ECB.pm%29 module APIs.) is an example, too.

Hi ifduyue, we've already adapted our code, so that's not a problem. It was just a bit confusing and it seemed to us the other way around was more intuitive. I didn't realize hashlib was working similarly here. So, I think you're right :)
