In many of the examples i have come across, i see IV is always being. Is it
not possible to use this API by setting IV to NULL? (As i understand for

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

Thanks Marek. If i select CBC mode encryption and i have data which is
not aligned to block, i assume padding will be taken by the API's itself.
Only if you use EVP. For low level APIs you have to manually add and remove
padding.

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 !

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.
