The Cybersecurity 202: Security community has its own encryption debate after discovery of new flaw

"Whether people decide to keep PGP or make the switch, the flaw shows how difficult it is to perfect the art of sending secure messages, said Riana Pfefferkorn, a cryptography fellow at Stanford University. 

“Even after withstanding years' worth of widespread scrutiny by security experts, a flaw in an encryption standard may still turn up,” she told me. “Plus, even if the vulnerability is fixed by the maintainers, users' configuration of their email client may not be perfect, potentially leaving them unwittingly exposed.”"
