User story #6363: Secure agent/server communication
Generate 4k rsa keys for agents
Added by Florian Heigl almost 10 years ago. Updated over 6 years ago.
Description
Hi,
CFEngine by default uses a 2Kbit RSA key.
There is no way in cf-key to change the value as of now.
On the other hand it is just a key, so it would be possible to create a far safer 4k one.
it would be viable to pre-seed that key, even for all hosts since rudder already has it's own CFEngine package.
I think on the root server / relay servers it is even more important, so at worst it could just be put in docs & manually done when setting up the root / relays.

You are clearly right that 2048 RSA key won't do forever. Actually, we should not even have to do compile anything to change key sizes, it should just be an option of cf-key.
Benoit, I'm sure you burn to look into cf-key code to see how the key size is chosen so that we can at least understand the complexity of the query.

In rudder-agent postinst, we call
/var/rudder/cfengine-community/bin/cf-key
This call can be simply replaced by:
openssl genrsa -des3 -out localhost.priv -passout "pass:Cfengine passphrase" 4096 openssl rsa -in localhost.priv -passin "pass:Cfengine passphrase" -RSAPublicKey_out -out localhost.pub

RSAPublicKey_out is the default when it is not supported, so use it when it works and don't when it doesn't
Silly ? yes
