| Jul 22, 2018 at 17:54 | comment | added | Dan Lenski | "the versatility of the block cipher" I have trouble with this part. What makes a block cipher inherently more versatile? Block ciphers can be used to encrypt and authenticate either both streams (e.g. TLS) or packetized data (e.g. ESP) and same for stream ciphers (e.g. TLS or DTLS). There are cases where a stream cipher seems more "natural" (e.g. encrypting audio) or a block cipher seems more "natural" (e.g. encrypting disks) but I just don't see a lot of gap in reasonable applications for either. | |
