Wikipedia:Articles for deletion/Quintuple-DES
no |reliable sources can be found. No cryptographer would ever design this, even an amateur like me can point holes in the idea -- the real cryptographic strength still at most 2112 like Triple-DES, despite 280-bit key, due to meet-in-the-middle attack; DES's small 64-bit block size is increasingly a problem with today's multi-terabyte storage devices and 10Gbit network interfaces. Also factual errors, DES hasn't "survived the test-of-time", there's a faster-than-brute-force attack http://crypto.junod.info/sac01.pdf
