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.

Hello,

i've yet another problem with lxyssl. It simply doesn't seem to work:

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

the main problem is: 'e' is empty..

Looking at the implementation of cfb_encrypt, it seems to me that the result is correctly pushed back into the stack..why can't I print it?

Any idea?

(for your curiosity, C implementation is here: http://code.google.com/p/luaxyssl/source/browse/tags/0.2/lxyssl.c#934 )

Thanks,

Valerio
