Prevent DOS against RSA authentication And now with an even older 1.6 GHz Turion 64 processor from 2005 (whereas the 2650e is from 2008 and the A8 is from 2012), I get a whooping 1695 ECDH/P-256 per second, as opposed to 318 RSA-2048 per second. There is something wrong in modern AMD processors, or in OpenSSL, or both. |

Prevent DOS against RSA authentication There's something definitely fishy with OpenSSL's implementation. The same code runs at over 1000 ECDH (with P-256) per second, on an old, cheap, 1.6 GHz AMD Athlon 2650e, which should be slower, not twice faster, than the more recent A8 (SHA-1 benchmark are more coherent: 240 MB/s for the 2650e, 340 MB/s for the A8). OpenSSL's EC code was contributed from Sun, and was supposedly audited carefully to be uncovered by existing patents, which means that OpenSSL developers are reluctant to modify it in any way. |

If SSL encrypts urls, then how are https messages routed? fixed typo and the SSL/SSH confusion (SSH has nothing to do with SSL and/or HTTPS). |
