HSE AES-CFB inputLength is limited

[cool_boy]

Hello！

I use AES-CFB mode and find that the input length is limited. But the input length of CFB mode can be any byte. Is there a problem here?

Hi @cool_boy 
Yes, the size of message must be a multiple of the cipher block size. If your message is not aligned to this size, it needs to be padded accordingly.
