Co je to "CSR" a jak to získám?

CSR je Certificate Signing Request (žádost o podpis certifikátu).

Základní přehled

Tento soubor obsahuje části informací o Vašem certifikátu a Vašem veřejném klíči.

Je použit CA čili Certification Authority (here : CAcert Inc.) to sign your cert (and obviously the info included in the cert).

The CA does not need the private key you have generated. You keep your private key secret.

The CA uses this CSR file to grab the info, verifying the info from your account and then generate the real certificate that you ( and your services) will use during secure communications with clients (HTTPS,SSL,POP3/SSL, etc.) and servers.

(based on Bruno ideas on CAcert support mailing list)
