"IPFire 2.15 Core Update 79 is finally arriving with many bug fixes and enhancements. Among the big changes with this update are lots feature enhancements that massively increase the security level of OpenVPN connections, some enhancements of the web user interface and a lot more awesome stuff under the hood. The OpenVPN capabilities have been massively extended by Erik Kapfer. The certificate authority that can be created on the OpenVPN page now uses much better hashes to protect the integrity of itself. The CA root certificate uses a SHA512 hash and a RSA key with length of 4096 bit. All new created host certificates use a RSA key with 2048 bit length and a SHA256 hash. Additionally, a set of Diffie-Hellman parameters can be generated for better protection of the session keys."
