Indeed, the number of recipients and their key parameters will be significant for the time to encrypt. Somewhat off-topic, but to provide a measurement for an encryption and signing using a tin-foil hat key of 15360 bit key, since I for various reasons keep one around in the first place, and don't really get to use it too often; On my email VM, which has 4 cores and 4 GB of RAM, the measurements are as follows: kristianf@ubuntu:~$ dd if=/dev/urandom bs=1024 count=200 > 200kfile kristianf@ubuntu:~$ time gpg2 -aser 43E67CF7 200kfile real 0m2.321s user 0m2.310s sys 0m0.000s where: kristianf@ubuntu:~$ gpg --list-key 43e67cf7 pub 15360R/43E67CF7 2006-12-15 uid Kristian Fiskerstrand <kristian.fiskerstr...@kfwebs.net> uid Kristian Fiskerstrand (Large key) <k...@kfwebs.net> sub 15360g/7CC80A28 2006-12-18 - -- - ---------------------------- Kristian Fiskerstrand http://www.sumptuouscapital.com Twitter: @krifisk - ---------------------------- Corruptissima re publica plurimæ leges The greater the degeneration of the republic, the more of its laws - ---------------------------- This email was digitally signed using the OpenPGP standard.
