Only if you use EVP. For low level APIs you have to manually add and remove
padding.

Bit confusing... are you saying that i need to add NULL termination at the
end of encrypted data? Isn't this wrong? I assume i shouldn't be NULL
terminating the input string which needs to be encrypted.

Stephen,
Does it mean we can't use AES without IV ?
As per XTS support in Openssl, i find the following function but don't see
any implementation for the same
AES_xts_encrypt(). I found the below link form which what i understand is
new file called e_aes_xts.c
should be present... am i missing so

That's what happens in C if you try to printf an array that's

Thanks Ken for pointing out the mistake... after changing to
AES_Decrypt(), it worked but i still see issue when i print the
decrypted output as it has extra non-ascii characters in it.
Below is the input
unsigned char text[]="test12345678abc2";
After decryption, i get the following string: Decr

No, this is something best left to the OpenSSL project. Otherwise,
you'll have a bunch of fractured documentation sprayed all over the
web.

I agree with you in general. I assumed the OP was just experimenting.
I use the raw AES_encrypt() because the standard I'm complying to uses a
non-standard counter mode. I had to construct it from scratch.

As an independent follower of this list, I'd just like say that even if
the documentation has its critics, the support provided here is
incredibly good !
