Is there a way to embed redundancy in a crypto key so that another key a few bits away can still decrypt the data?

- clysm 4y agoDES (and TDES) has 1 parity bit for every 7 bits of key. Nobody really uses it as far as I've seen (e.g. they just generate random keys with invalid parity), but it's built in to the key itself.
- ip26 4y agoParity only tells you the key is corrupt, it can't correct the block :/
- kevin_thibedeau 4y agoEncode it for storage with FEC.
