base64 encoding
#1
Hi,

I am trying to encode the following string with mime.b64 and when I decode it adds this string with a half of the encoded string.  I found the following post regarding this matter in a lua forum,  http://lua-users.org/lists/lua-l/2010-03/msg00832.html.  This looks like exactly what I'm getting.  Any help would be gratefully appreciated.

Thanks,

Roger

You can use built-in encdec library for base64:

That works, thank you

Using the base64 encdec library we encounter a strange behavior in the conversion of the string "rbms".
The result of the reconversion is "rbmss". This does not happen in the case of different strings (see attached image).
We're probably missing something, but we are concerned because we use the conversion base64 to transfer entire libraries in the LM.

This is a bug in encdec. This will be fixed in the next build. In the meantime you can use mime.unb64 from LuaSocket (http://w3.impa.br/~diego/software/luasoc...html#unb64)
