Fork of LuaCrypto, which enables encryption and decryption through OpenSSL

luacrypto's Issues

sorry, how to use crypto.verify to verify rsa

The example is too less. I try so many time but failure.

Deprecate?

It seems this is no longer maintained.
To prevent confusion, could you officially deprecate the library?

FWIW, I've now switched over to luaossl.

Update rockspec for luacrypto to support 5.3

Can you please make this change in the mainline rockspec?

/usr/bin/ld final link failed bad value

Hi Michal, I'm trying to install luacrypto by using luarocks in Ubuntu 16.10. I first installed luarocks then I tried running

luarocks install lapis

but I got an error message saying that the luacrypto package couldn't be installed because it couldn't find the evp.h file of openssl.

So, as suggested in the error message, I tried with

luarocks install luacrypto OPENSSL_DIR=/usr/local OPENSSL_LIBDIR=/usr/local/ssl/ lib OPENSSL_INCDIR=/usr/local/ssl/ include

This time I got the following output and error message:

Installing https://rocks.moonscript.org/luacrypto-0.3.2-2.src.rock...

/usr/bin/ld final link failed bad value
collect2: error: ld returned 1 exit status
Error: Build error: Failed compiling module crypto.so

I understand that I should recompile luacrypto with the -fPIC flag? Is that correct? If this is the solution, as I'm not expert about libraries and compilation, could you please let me know how I can recompile luacrypto (that I already downloaded) with this flag?

Note: I'm using openssl 1.0.2k.

Thanks in advance

Stefano

when I use sha1WithRSAEncryption to verify java SHA1WithRSA ,result is false

luacrypto's sha1WithRSAEncryption is different with java's SHA1WithRSA?

Can't build with cmake

When I try to run cmake .\ on the luacrypto directory I get:

If I run:

libeay32.dll being the downloaded crypto lib and ssleay32.dll the sll lib, which I'm not even sure if they are because I really don't know what the cryptlib and ssllib are supposed to be name or how I'm supposed to get them. I installed them from this website. This is the output:

`C:\Users\Admin\Desktop\luacrypto-master>cmake -D CRYPTO_LIBRARY=C:\OpenSSL-Win32\bin\libeay32.dll -D SSL_LIBRARY=C:\OpenSSL-Win32\bin\ssleay32.dll .\

Supposedly it compiled but I can't find luacrypto.dll anywhere in luacrypto-master.
I'm running windows 10 (unfortunatly..) and I'm using the latest installation of cmake.

doesn't build and install on ubuntu 12.10, probably not on any debian-derived distro

Debian/ubuntu name the lua package lua5.1, lua5.2, etc... so the ./configure in luacrypto fails to find lua. I modified the configure.ac to look for lua5.1 package, ran autoreconf, and it detected lua5.1.

But, it doesn't build:

make[2]: Entering directory `/home/sroberts/s/luacrypto/luacrypto/src'
/bin/bash ../libtool --tag=CC --mode=link gcc -g -O2 -module -avoid-version -o crypto.la -rpath lcrypto.lo -lssl -lcrypto
libtool: link: only absolute run-paths are allowed

No idea what's going on here, so, I abandoned the directions in INSTALL, and tried cmake. This works better:

cmake CMakeLists.txt

make

make install

But, it doesn't install into a location where lua's package.cpath will search:

/usr/local/lib/lua/crypto.so

is not in package.cpath:

% lua -e "print(package.cpath)"
./?.so;/usr/local/lib/lua/5.1/?.so;/usr/lib/i386-linux-gnu/lua/5.1/?.so;/usr/lib/lua/5.1/?.so;/usr/local/lib/lua/5.1/loadall.so

I know that autodetection of lua is painful and non-standard, but two suggestions:

Modify INSTALL to recommend people use cmake if they have it (and consider removing the auto- cruft from the repo, it should be in released tarballs, if you release, but doesn't have to be checked in).

Train cmake to derive the crypto.so install path from package.cpath (probably most portable), or try to get the path from pkg-config:

pkg-config lua5.1 --define-variable=prefix=/usr/local --variable=INSTALL_CMOD
/usr/local/lib/i386-linux-gnu/lua/5.1

The crypto.so did appear to be built correctly, with cmake, though, once I move once I've moved it into the package.cpath:
% lua -l crypto -e "print(crypto._DESCRIPTION)"
LuaCrypto is a Lua wrapper for OpenSSL

Error: Build error: Failed compiling object src/lcrypto.o

I am trying to install luacrypto and i get this error . My gcc version is 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC). I have Lua 5.1.4 .

An help will be appreciated?

key length issue in crypto.encrypt API

I am using crypto.encrypt("AES128", text, key) API to encrypt our data. But whenever i pass key whose size is more than 32 bytes/char it say invalid key.

Is there anyway i can pass longer keys ? or this is a bug ?

ability to do OpenSSL initialization outside of luacrypto

Hi,

Is it possible to change the module so that OpenSSL environment initialization is conditionally disabled in luacrypto so that application which embeds Lua and luacrypto can do OpenSSL environment initialization by itself? By the initialization I mean calls OpenSSL_add_all_digests() and OpenSSL_add_all_ciphers() in luaopen_crypto(). This is necessary in certain use cases; particularly it is more or less required for multi-threaded applications where application creates multiple independent Lua environments in different threads where each Lua environment loads luacrypto library. The problem is that OpenSSL environment initialization should be done only once per-process; if you try to do OpenSSL enviroment initialization in multiple threads at the same time it causes crashes as corresponding API is not supposed to be called in parallel. Also in general for multi thread use case OpenSSL environment needs more complex initialization logic.

Unable to decrypt cipher encrypted by Crypto-JS (AES default)

Hello,
I am not able to decrypt back what was encrypted using Crypto-JS in browser Javascript:

// Encrypt
var ciphertext = CryptoJS.AES.encrypt('testingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtestingtesting', '&&nH8P3bxk+?C4gR');
 
// Decrypt
var bytes  = CryptoJS.AES.decrypt(ciphertext.toString(), '&&nH8P3bxk+?C4gR');
var plaintext = bytes.toString(CryptoJS.enc.Utf8);

console.log(plaintext);

I can decrypt it in Java using:
Cipher.getInstance("AES/CBC/PKCS5Padding")
But, I get
error:0606506D:digital envelope routines:EVP_DecryptFinal_ex:wrong final block length
when I try to do it with LuaCrypto. Here is the code:

local crypto = require("crypto")
local cipherText = 'U2FsdGVkX1859eIyt4M7VHNBl9BGMdsemPYAADKmqs9sltwKINfzVMci0Vw1NLr73Iti67zQ0+JoqVcL59Gcp+4R5NY6wg2n3r0wqLcQRc7PkIGpgup1UJp4DzhXSIGHz08Eu/nEbt3jAh3S4GVUoVFbXLluf/BvedTGdsqcN2EPL9S/WQOc5QDyl9OQjpBl+QS56nWL0DO6iR/6CIoEuQ+zC/7KTpBw2jQf8sxuDNptZzwKLlDi2sWSaeCkvPj+m8zheAlnZzVc+L5JeLdcx7WkIRQImNs9P5bkhXmiK2nZnw4yco3QHbzRkRBJiB3HgdYDauHsuKmR21zv9VLjAcGTrZjiUbtrBfuTRawKOiAFm599Inbq+Ugu9n4RelQ2CTdxwDfe3ZE3kscP3dyAmg=='

ngx.say(crypto.decrypt('aes-256-cbc', cipherText, '&&nH8P3bxk+?C4gR'))

Could someone please help me with server side decryption?

how to set up on windows?

could you please clarify how to proceed with installation?

BIO memory leak with pkey_from_pem and x509__x509_from_string?

It looks like pkey_from_pem and x509__x509_from_string don't BIO_free their memory object when they succeed, only when they fail. Would this result in a memory leak? Or do the pkey and x509 cert objects retain a reference to the allocated memory and free it when they are freed?

How to install and use luacrypto in Lua-Corona application on Windows platform? Is this a valid combination? Please advise.

I cannot compile it in fedora 20

reset IV method

Now we can not effective implement CTR algorithm with custom counter.
But if we implement resetiv method then we can write:

local aes = crypto.encrypt.new('aes-256-ctr', KEY)
local IV = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}
for b, e in ichunks(msg, block_size) do
  inc_iv(IV)
  aes:resetiv(IV)
  local chunk = string.sub(msg, b, e)
  chunk = aes:update(chunk) -- or even better aes:update(msg, b, e) 
end

I realy do not know is this valid in OpenSSL update iv, but it work.
in my test this method 10 times slower then simple aes-256-crt.
this my implementation moteus-iv

installed, not sure where to find it

i installed luacrypto, but when i run my program i still get

ideas?

why not support openssl 1.1.0 or higher?

I got an error for luacrypto.c
