I write books and build things. Mostly related to computer security. Here are some things that may be of interest:<p>- My book Bulletproof TLS and PKI (https://www.feistyduck.com/books/bulletproof-tls-and-pki/) provides a comprehensive and practical coverage of SSL/TLS and PKI. The second edition was released in January 2022.<p>- I also maintain the free OpenSSL Cookbook, which focuses on command-line usage: https://www.feistyduck.com/books/openssl-cookbook/<p>- My startup Hardenize https://www.hardenize.com (now acquired by Red Sift) aims to help everyone deploy modern security standards by providing free assessments to everyone.<p>Previously, I built SSL Labs. Before that, ModSecurity.<p>[ my public key: https://keybase.io/ivanr; my proof: https://keybase.io/ivanr/sigs/LiVhyast_FE7MnLvqIDRD7yl-KGXtrEaGfBUX-K_6D0 ]
