Hi! I am writing a new JtR format using custom code to crack such PEM files. On our "bull" system (with AMD FX-8120 processor), I get a combined speed of around 14000 c/s when attacking the test.pem file. The code is pretty experimental at the moment, https://github.com/magnumripper/JohnTheRipper/pull/1848 Dhiru
