[zhiguo zhao <zhaozg@...>]

  Hi,

  

  I release lua-openssl v0.1.0 as alpha, and it have long distance touch perfect level.

  Thanks all for care about it, you can download it from https://github.com/zhaozg/lua-openssl/zipball/0.1.1

  https://github.com/zhaozg/lua-openssl

  http://code.google.com/p/lua-openssl/

  Here is a example to use it, more please to see test script.

-------------------------------------------------------------

local openssl = require 'openssl'

--dump a table 

function dump(t,i)

        for k,v in pairs(t) do

                if(type(v)=='table') then

                        print( string.rep('\t',i),k..'={')

                                dump(v,i+1)

                        print( string.rep('\t',i),k..'=}')

                else

                        print( string.rep('\t',i),k..'='..tostring(v))

                end

        end

end

-- get sha1 digest method

local md = openssl.get_digest('sha1')

local msg = string.rep('I love lua.',1000)

local digest1 = md:digest(msg)

-- get digest method context

local mdc=md:init() 

for i=1,1000 do

        mdc:update('I love lua.')

end

local digest2 = mdc:final()

assert(digest1==digest2)

print('digest OK')

print(string.rep('-',78))

-- create a rsa private key

local pkey = openssl.pkey_new('rsa' ,1024, 0x10001)

print('is_private:',pkey:is_private())

print(string.rep('-',78))

print(pkey:export())

print(string.rep('-',78))

local t = pkey:parse()

dump(t,0)

print('pkey generate OK')

print(string.rep('-',78))

-- create a certificate

local args = {}

args.digest = 'sha1WithRSAEncryption'

local dn = {commonName='zhaozg', emailAddress='zhaozg@gmail.com'}

local csr = openssl.csr_new(pkey,dn,args)

t = csr:parse()

dump(t,0)

print('csr generate OK')

print(string.rep('-',78))

-- make a self sign certificate

args = {}

args.digest = 'sha1WithRSAEncryption'

args.serialNumber = '1234567890abcdef' --hexencode big number

args.num_days = 365       --here need to more flexble

local x509 = csr:sign(nil,pkey,args)

local t = x509:parse()

dump(t, 0);

print('self signed certificate generate OK')

print(string.rep('-',78))

local pubkey = x509:get_public()

-- sign something.

local signed_data = openssl.sign('I love lua',  pkey , 'sha1')

print('#signed_data:', #signed_data)

print(md)

local verified = openssl.verify('I love lua', signed_data, pubkey, md)

assert(verified)

print('sign and verify OK')

-- please wait more sample
