     8|| AES-CBC [8] || 256 || Good [5] ||  A good choice due to common support for hardware acceleration??? Really? We don't support hardware acceleration. Never used alone, always with ElG+SessionTag [8] ||

    19 || DSA || 1024 || Poor [5] || ||
     28|| DSA [8] || 1024 || Poor [5] || We use DSA for all signatures. We do not use ElG as it was deemed too slow. That's why every Dest and RI has two keys, one for crypto and one for signing. ||
