I'm making a distributed PHP app that I was to have RSA security functionality, and I don't want to rely upon (although I may use if available) PHP extensions to do the work, hence I need a pure PHP solution as a backup. Does an RSA solution for PHP exist (I did some googling and couldn't find anything...) or do I have to make one? I've found a really cool Perl RSA Module which I could port, but i'm lazy, so I'm asking if it's already been done (and, of course, everyone knows Perl ~= s/ux0r//)
I've already started converting... so I may just keep going, but I'd love some other inspirational sources!
Thanks!
