Source Code Encryption

I'm trying to find the best software out there for encrypting/protecting the source code of a site. I've found a few solutions, however I'm open to hearing any suggestions.

Thanks!

Encryting source code isn't a good idea.

There would be a way to do it in php, by having the code it renders encrypted using MD5 or Sha1, php.net look into it MD5 is most supported, but then again it can be cracked using rainbow tables, and to get the hash they would only have to view your source...

http://php.net/md5

Sha1 on the other hand is almost impossible to decode, I would go with that.

There are Javascript solutions out there but they are really a waste of time as anyone determined to view your source can just change a couple of lines of the script to write your source to a file.

Then there are problems if you are trying to make your site standards compliant and accessible, (which you should be doing), as encrypting the code will stop it being so.

And then there are problems with SEO - a search engine spider reads the HTML of the page and if that page is encrypted then there's nothing for the spider to read.

Why would you encrypt your source code?

Other people have let you look at their source code, so that you could learn from it (find out how they did a certain something something in the web page), or look at how it was all coded.. so why would you want to encrypt yours?

You could easily write in a search engine if else to decrypt the code for Google Bot etc... am I right?

Those Javascript ones are complete worthless, that isn't real encryption, all they have to do is find the place where you did it and use the decode function.. go real encryption alogrithms
