Re: [sr-dev] TLS key recommendation

" Try to avoid using keys larger then 1024 bytes. Large keys significantly slow down the TLS connection handshake, thus limiting the maximum SIP-router TLS connection rate. "

Is this still a valid recommendation? Based on which size of CPU/system?

Hi Olle,

i'd think that today we should suggest a larger key. I've found this page: http://www.keylength.com/en/compare/

according to it newer sources suggest a value of at least 1536 bits for asymmetric keys.
