From 779a850e0fb967aac79124c7e18b14706d5f2652 Mon Sep 17 00:00:00 2001 From: Frank Denis Date: Tue, 25 Feb 2025 15:03:50 +0100 Subject: Add optional support for AEGIS encryption AEGIS is a new family of authenticated encryption algorithms that offers stronger security, higher usage limits, and better performance than AES-GCM. This pull request adds support for a new `-aegis` command-line flag, allowing AEGIS-128X2 to be used as an alternative to AES-GCM on CPUs with AES acceleration. It also introduces the ability to use ciphers with different key sizes.
