PKCS10Client - Man Page

Used to generate 1024-bit RSA key pair in the security database.


PKCS10Client -d NSS-database -h NSS-token -p NSS-password -a algorithm [-l rsa-key-length] [-c ec-curve-name] -o output-file -n subject-DN

To get a certificate from the CA, the certificate request needs to be submitted to and approved by a CA agent. Once approved, a certificate is created for the request, and certificate attributes, such as extensions, are populated according to certificate profiles.


The PKCS #10 utility, PKCS10Client, generates a RSA or EC key pair in the security database, constructs a PKCS #10 certificate request with the public key, and outputs the request to a file.

PKCS #10 is a certification request syntax standard defined by RSA. A CA may support multiple types of certificate requests. The Certificate System CA supports KEYGEN, PKCS #10, CRMF, and CMC.


PKCS10Client parameters:

-d NSS-database

The directory containing the NSS database. This is usually the client's personal directory.

-h NSS-token

Name of the token. By default it takes internal.

-p NSS-token

The password to the token.

-a algorithm

The algorithm type either rsa or ec. By default it takes rsa.

-l rsa-key-length

The RSA key bit length when -a rsa is specified. By default it is 1024.

-c ec-curve-name

Eleptic Curve cryptography curve name.
   Possible values are (if provided by the crypto module):
   nistp256 (secp256r1), nistp384 (secp384r1), nistp521 (secp521r1), nistk163 (sect163k1),

   sect113r1, sect113r2, sect131r1, sect131r2.

-o output-file

Sets the path and filename to output the new PKCS #10 certificate in base64 format.

-n subject-DN

Gives the subject DN of the certificate.

-k enable-encoding

true for enabling encoding of attribute values; false for default encoding of attribute values;
   default is false.

-t temporary

true for temporary(session); false for permanent(token); default is false.

-s sensitivity

1 for sensitive; 0 for non-sensitive; -1 temporaryPairMode dependent; default is -1.

-e extractable

1 for extractable; 0 for non-extractable; -1 token dependent; default is -1.

Also optional for ECC key generation:

-x ecdh-ecdsa

true for SSL cert that does ECDH ECDSA; false otherwise; default false.

-y ski-extension

   true for adding SubjectKeyIdentifier extension for self-signed CMC shared secret requests;
   false otherwise; default false.
   To be used with request.useSharedSecret=true when running CMCRequest.
