Is this really required ?

Hi @Waotest

Thanks for contacting wolfSSL. Could you tell us a bit about your project using wolfCrypt Python?

I'm reviewing your question with the team.

Thanks,
@embhorn

im encrypting in python and decrypting in c. i need the file length to stay the same that's why i use ctr mode. but your python wrapper requires the input to be multiple of block size which should not be required for ctr aes.
