Copy and paste code, interactively line by line to verify the length via #e which doesn't show the problem you mentioned.

Hi,

just to be clear: are you saying that one of the 2 code snippets I've posted is working on your machine? 

Or, you're saying that you have some other variant of this same functionality that is working fine for you? If so, I'd be very curious to see it. 

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")

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
