lunarmodules / md5 Goto Github PK

luaL_setfuncs in src/compat-5.2.c doesn't work if nups > 0. See keplerproject/lua-compat-5.2@adf9db4a5. Currently you don't need upvalues for this module, so this is not a pressing issue ...

Please provide a download archive tarball/zipball, either in tags or downloads.

As I understand it, the current Version is 1.2?
there is some mention of 1.1.2, most prominent in the README.md which is the first thing a user of github sees.

I think lines 25 and 26 in Makefile should be swapped:

install: src/$(MD5_LIBNAME) src/$(DES56_LIBNAME)
	cp src/$(DES56_LIBNAME) $(LUA_LIBDIR)
	mkdir -p $(LUA_LIBDIR)/md5
	cp src/$(MD5_LIBNAME) $(LUA_LIBDIR)/md5/
	mkdir -p $(LUA_DIR)
	cp $(MD5_LUAS) $(LUA_DIR)

Otherwise copy operation for $(DES56_LIBNAME) may attempt to place it in a non-existent directory causing the whole make install to fail.

Hello,

Currently I'm trying to setup cgit to use libravatar using lua script and one of the dependency is this lua md5. However, when I used it with my cgit instance I got error:

fatal: Lua error in /usr/local/lib64/cgit/filters/email-libravatar-korg.lua: error loading module 'md5.core' from file '/usr/local/lib64/lua/5.1/md5/core.so':
	/usr/local/lib64/lua/5.1/md5/core.so: undefined symbol: lua_settop

Below is my lua script to access the libravatar:

local md5 = require("md5")

function filter_open(email, page)
        buffer = ""
        hexdigest = md5.sumhexa(email:sub(2, -2):lower())
end

function filter_close()
        html("<span class='libravatar'><img class='inline' src='//seccdn.libravatar.org/avatar/" .. hexdigest .. "?s=13&d=retro' /><img class='onhover' src='//seccdn.libravatar.org/avatar/" .. hexdigest .. "?s=128&d=retro' /></span>" .. buffer)
        return 0
end

function filter_write(str)
        buffer = buffer .. str
end

My Lua version is 5.1.5

Please kindly help what is wrong with my setup?

Thank you.

how to use c api? provide some demo please

md5_init(m);  
md5_update(m, "hello", strlen("hello"));  
md5_update(m, "world", strlen("world"));  
md5_finish(m, hash);  

hash: a48b171ee450c14dab8e7162cdce3f8d

md5_init(m);  
md5_update(m, "helloworld", strlen("helloworld"));  
md5_finish(m, hash);  

hash: fc5e038d38a57032085441e7fe7010b0

In Python or other C implementations, eg RFC 1321

hash_md5 = hashlib.md5()
hash_md5.update("hello")
hash_md5.update("world")
print(hash_md5.hexdigest())

hash: fc5e038d38a57032085441e7fe7010b0

hash_md5 = hashlib.md5()
hash_md5.update("helloworld")
print(hash_md5.hexdigest())

hash: fc5e038d38a57032085441e7fe7010b0

This library provides two ways to encrypt and decrypt data: one "based on MD5 and CFB" and the other one "based on DES with 56-bit keys". MD5 is not used in any symmetric cipher commonly accepted as secure and DES has been known to be insecure since at least 2001. While this library may still be useful for legacy reasons, would you consider adding a warning in your documentation and readme so that users don't mistakenly think this library provides them with secure ciphers?
