Can TSA use a key size bigger than 2048?


#1

Can the TSA server use a key that is made using 4096 bits, or only 2048 (ssh-keygen default)?

I am not sure if this answers your questions, but I used RSA 4096 keys for all of those keys required here: https://concourse-ci.org/install.html#generating-keys

It worked without any problems with Concourse v4.2.2. It should make a difference, but I use the Kubernetes Helm Chart for Concourse v3.7.3 and generated the keys via Terraform TLS provider.
