There is enormous difference between rolling your own crypto primitives and using existing primitives to create a protocol.

- tptacek 9y agoNo, there isn't. Most crypto vulnerabilities happen in the joinery between primitives. If you rolled your own block cipher, it's less likely that the cipher would be broken than that your protocol would be broken with a vulnerability that would apply equally well to AES. Obviously, don't make your own block cipher, either.
