However, no doubt there are still some users and applications that are stuck using even older versions of OpenSSL. Indeed, CentOS/RHEL 7 and earlier still use OpenSSL 1.0.2. These are widely used in shared hosting. We ended up implementing Workaround #2 in order to bring OpenSSL 1.0.x into parity with the behaviour of 1.1.0+. It would be nice--would have been helpful for me, at least--to have fleshed-out code examples. Thank you to everyone who maintains OpenSSL and who’s helping us all through this transition. cheers, -Felipe Gasper
