make init topca=name\n\
|
|
Creates the initial top-level CA structure\n\
|
|
make newca name=newcaname ca=parentca\n\
|
|
Creates a new sub-CA that can be used for certificates later.\n\
|
|
make newcert name=foo ca=parentca\n\
|
|
Create private key and csr, then issue the certificate (named foo.*)\n\
|
|
make p12 name=foo ca=parentca\n\
|
|
Same as newcert, but additionnaly creates a pkcs12 file to ship client certificate to Windows or Mac\n\
|
|
make ship name=foo ca=parentca\n\
|
|
Create an archive with the data for the client (useful for freeDiameter peers)\n\
|
|
make revoke name=foo ca=parentca\n\
|
|
Revokes the certificate foo.cert issued by parentca and regenerates the CRL.\n\
|
|
make gencrl ca=caname\n\
|
|
Regenerates the CRL of CA caname. Should be run periodically.\n\
|
|
