Diffie Hellman and TLS with nonsense parameters - Hanno's blog edit / delete

Apparently quite a lot of TLS implementations will happily accept 15 as a prime for DH key exchange. Presumably even if they were checking you could rely on the probabilistic test too...

Keys/second/watt for various architectures. The manycore ones do very well -- they aren't fast as such but they're very power-efficient for the performance they get.
