Hello Perl Community. I was trying to build a secure string library in C resistant to buffer overflow vulnerabilities when I realized parsing inputs matters. Perl is well known for string rendering. What books would you recoendnd to a proficient C coder that is trying to learn Perl to master the art of parsing and editing strings to avoid common security exploits?
