XOR encryption is unbreakable with an one-time pad that matches the message length (that's basically AES CTR). It's one of the most secure cryptography primitives we have.
The problem is deciding to use home-grown encryption.
- tptacek 7y agoAES CTR isn't a one-time pad. It's as strong as AES, not theoretically unbreakable.
- zamalek 7y ago"Basically" is the key word there.
- loeg 7y agoThis isn't a one-time pad. It's reused for every message.
- herio 7y agoI usually say that encryption is the easy part. Just use XOR and you are good. All the complicated bits are related to key management.
