--signkey-password <pass> : Password for the CA signing key
--signkey-pwd <pwd>       : Alternative password option for CA signing key
--parentkey-password <p>  : Password of parent key; SRK password of TPM
--parentkey-pwd <pwd>     : Alternative password option for SRK password
--issuercert <filename>   : PEM file with CA cert
--out-cert <filename>     : Filename for certificate
--modulus <hex string>    : The modulus of the public key

                            default: secp256r1
--serial <serial number>  : The certificate serial number
--days <number>           : Number of days the cert is valid;
                            -1 for no expiration

--subject <subject>       : Subject such as location in format
                            C=US,ST=NY,L=NewYork; not used with TPM1.2
--add-header              : Add the TCG certificate header describing
                            a TCG_PCCLIENT_STORED_CERT for TPM1.2 NVRAM
--tpm2                    : Issue a TPM 2 compliant certificate
--allow-signing           : The EK of a TPM 2 allows signing;
                            requires --tpm2
--decryption              : The EK if a TPM 2 can be used for key
                            encipherment; requires --tpm2
--print-capabilities      : Print capabilities and exit
--version                 : Display version and exit
