How to setup a intermediate compatible SSL website with LetsEncrypt certificate

Howto Forge - Tue, 19/01/2016 - 4:29pm
Many people have decided to implement Let's Encrypt into their production sites. I find this still a very bad idea to be done without being very (but really very) careful. Let's Encrypt brings you freedom but also limits you in using the certificate with SHA-256 RSA Encryption. Support for SHA-2 has improved over the last few years. Most browsers, platforms, mail clients and mobile devices already support SHA-2. However, some older operating systems such as Windows XP pre-SP3 do not support SHA-2 encryption.
