Hello Gary, 

i've tried with the security.lua wrapper, same result:

require"security"

data="">

k = security.hash.engine('md5'):digest('abcd')

aes_cfb = security.crypto.engine('aes_cfb', k, k)

e=aes_cfb:encrypt(data.."a")

d=aes_cfb:decrypt(e)

assert(d==data.."a")

The result aes_cfb:encrypt is again an empty string.

there is a simple wrapper security.lua in the distribution. you may cross check with that. I believe I have test cases against them and were ok at the time of writing.

function ex2()

key='abcdabcdabcdabcd'

data="">

iv=lxyssl.hash('md5'):digest(key)

e=lxyssl.aes(key):cfb_encrypt(data .. "a",iv)

d=lxyssl.aes(key):cfb_decrypt(e,iv)

assert(d==data .."a")

end
