Ofcourse, there is the Net::SSLeay interface to openssl. In addition to some high-level routines, it seems to have interfaces to a lot of the lower-level C library functions too. Have you checked it out?

Update: You might want to specify what kind of client you are going to make. I'm wondering why you need ssl, unencrypted tcp and udp at the same time. :-)
