- tptacek 14y agoThat's a table of stream ciphers benchmarked against AES, a block cipher, in CTR mode.
- dchest 14y agoYes. Apart from disk encryption, they are pretty much interchangeable (OP talked about IPSec).
- tptacek 14y agoAES is normally benchmarked against other block ciphers. It might not be fair to compare the performance of a native stream cipher to that of AES rigged up as a stream cipher with CTR.
- floody-berry 14y agoWhat makes the comparison unfair?
- tptacek 14y agoThe other ciphers are natively stream ciphers, and AES is a block cipher adapted via CTR mode to be a stream cipher.
- floody-berry 14y agoI'm still missing what makes it unfair. Are other modes of AES potentially faster? Does AES provide something that stream ciphers don't? Are Salsa20/Chacha20 unable to be compared to anything because they're native stream ciphers that look like a block cipher in CTR mode under the hood?
- tptacek 14y ago1. Yes. 2. Yes. 3. No.
