Implement pycrypto aes in lua.
I use pycrypto to encrypt with aes in client, and openresty lua-resty-string aes to decrypt in server.
And I cannot easily handle these, because the decrypt content is not the same as source. I known that may be I use lua-resty-string wrong, but I think the best way is to implement pycrypto aes in lua, so I use pycrypto source and begin to integrate.
Now I have implemented aes mode ECB, CBC, CFB, OFB. I don't want to implement CTR mode because I found that writing pycrypto default counter is not easy. If you want to use CTR mode, you can implement yourself and supply a custom counter.
Very easy:
make
make install
You may assign LUA_INCLUDE_DIR and LUA_LIB_DIR when make, default is for openresty with luajit.
require "pycrypto_aes"
local aes = pycrypto_aes.new(key, pycrypto_aes.MODE_ECB)
local cipher = aes:encrypt(plain)
ngx.say(ngx.encode_base64(cipher))
ngx.say(aes:decrypt(cipher))
If you found any bug, please contact me. Thank you very much!
