General options --ca-url URL Required. Base URL of the caucase service to access. Ex: http://caucase.example.com:8000 --ca-crt PATH Default: cas.crt.pem Path of the service CA certificate file. Updated on each run. --user-ca-crt PATH Default: cau.crt.pem Path of the user CA certificate file. See --update-user . --crl PATH Default: cas.crl.pem Path of the service revocation list. Updated on each run. --user-crl PATH Default: cau.crl.pem Path of the service revocation list. See --update-user . --threshold DAYS Default: 31 Skip renewal when certificate is still valid for this many days. See --renew-crt . --key-len BITS Default: 2048 Size of the private key to generate. See --renew-crt . --user-key PATH A file containing a private key and corresponding certificate, to authenticate as a caucase user. --mode {service|user} Default: service Caucase personality to query. Anonymous actions --send-csr PATH Submit given certificate signing request, and print the identifier under which the server accepted it (see --get-crt and --get-csr). --get-crt CSR_ID CRT_PATH Retrieve the certificate corresponding to the signing request with identifier CSR_ID, and store it in CRT_PATH. If CRT_PATH exists and contains a private key, verifies it matches received certificate, and exit before modifying the file if it does not match. See also --get-csr . --revoke-crt CRT_PATH KEY_PATH Revoke the certificate at CRT_PATH. Revocation request must be signed with corresponding private key, read from KEY_PATH. Both paths may point at the same file. --renew-crt CRT_PATH KEY_PATH Renew the certificate from CRT_PATH with a new private key. Upon success, write resulting certificate in CRT_PATH and key in KEY_PATH. Both paths may point at the same file. --get-csr CSR_ID CSR_PATH Retrieve the signing request with identifier CSR_ID, and store it in CSR_PATH. Allows checking whether a signature request is still pending if --get-crt failed, or if it has been rejected. --update-user In addition to updating CA certificate and revocation list for service more, also update the equivalents for user mode. You should not need this. Authenticated actions These options require --user-key . --list-csr List pending certificate signing requests. --sign-csr CSR_ID Sign the pending request with identifier CSR_ID. --sign-csr-with CSR_ID CSR_PATH Sign the pending request with identifier CSR_ID, replacing its extensions with the ones from CSR_PATH. --reject-csr Reject pending request with identifier CSR_ID. --revoke-other-crt CRT_PATH Revoke certificate read from CRT_PATH, without requiring access to its private key. --revoke-serial SERIAL Revoke certificate with given serial. When not even the original certificate is available for revocation. Special actions --help Display this help and exit.
