[erlang-questions] blowfish CFB mode in Crypto application

[Igor Nesterov]

Hi,

I'm using block_encrypt function from crypto application with blowfish 
cipher in CFB mode and find that block_encrypt doesn't allow to continue 
sequential encryption in this mode.  Underlying BF_cfb64_encrypt 
function changes parameters iv and num, so they can be passed to the 
next call.And bf_cfb64_crypt from C part of crypto application doesn't 
pass those parameters back to erlang side, so it's impossible to obtain 
new parameters for the new call. Is there another solution exists? Or 
it's better to make patch?
