Security & Encryption & Open SSL

[icekat83]

Hey,

 

I wasn't sure where to post this. I've been coding for a while but still know very little about security. I'm hoping someone can direct me someplace I can learn a bit more about encryption, what SSL is and how it's different to Open SSL, how Open SSL can work (considering what I understand of open source wouldn't that make it more hackable?) and security.

 

I do know the basics. I know about SQL injection, something I try to protect against, and I know you can use the inbuilt MD5 function to encrypt passwords one way (which I do) but that's about it.

 

If people want to post here that's cool but I don't expect that. I'm just hoping for some good info links. And if people can help me work out how to test how secure/insecure my scripts are that would also be awesome. 

 

Thanks,

IceKat.
