| Sep 29, 2018 at 13:28 | comment | added | rmalayter | I believe djb (the creator of Salsa and ChaCha) considers all 128-bit-key symmetric primitives to have less than 128-bit security due to multi-target attacks. Hence djb always recommends 256-bit symmetric keys but doesn’t necessarily claim 256-bit security. | |
