Overview

This page describes the process to enroll a certificate using a PIN-authenticated profile (e.g. caDirPinUserCert).

Availability: Since PKI 11.6.

Prerequisites

  • Configure PIN-authenticated profile.

  • Generate a certificate request and store it in a file (e.g. testuser.csr).

Enrollment using pki ca-cert-issue

The enrollment can be done using pki ca-cert-issue command.

Specify the profile name, the CSR file, the username in the following command, and it will prompt for the password and the PIN:

$ pki ca-cert-issue \
    --profile caDirPinUserCert \
    --csr-file testuser.csr \
    --username testuser \
    --password \
    --pin \
    --output-file testuser.crt
Password: ********
PIN: ********

The password and PIN can also be specified with --password-file and --pin-file options.

The certificate will be stored into testuser.crt.

Availability: Since PKI 11.6

Enrollment using pki ca-cert-request-submit

The enrollment can be done using pki ca-cert-request-submit command.

Specify the profile name, the CSR file, the username in the following command, and it will prompt for the password and the PIN:

$ pki ca-cert-request-submit \
    --profile caDirPinUserCert \
    --csr-file testuser.csr \
    --username testuser \
    --password \
    --pin
Password: ********
PIN: ********
-----------------------------
Submitted certificate request
-----------------------------
  Request ID: 0xfd5377c93db8f0ed016de1d688e27f7e
  Type: enrollment
  Request Status: complete
  Operation Result: success
  Certificate ID: 0x784127bb5291d998224a9426aea15c2b

The password and PIN can also be specified with --password-file and --pin-file options.

The certificate can be retrieved with the following command:

$ pki ca-cert-export <cert ID> --output-file testuser.crt

Enrollment using XML

The enrollment can also be done manually using XML messages.

Then retrieve the template for the XML request for the profile with the following command:

$ curl \
    -k \
    -s \
    -H "Content-Type: application/xml" \
    -H "Accept: application/xml" \
    https://$HOSTNAME:8443/ca/rest/certrequests/profiles/caDirPinUserCert \
    | xmllint --format - \
    > request.xml

Insert the username of the LDAP user with the following command:

$ xmlstarlet edit --inplace \
    -s "/CertEnrollmentRequest/Attributes" --type elem --name "Attribute" -v "testuser" \
    -i "/CertEnrollmentRequest/Attributes/Attribute[not(@name)]" -t attr -n "name" -v "uid" \
    request.xml

Insert the password of the LDAP user with the following command:

$ xmlstarlet edit --inplace \
    -s "/CertEnrollmentRequest/Attributes" --type elem --name "Attribute" -v "Secret.123" \
    -i "/CertEnrollmentRequest/Attributes/Attribute[not(@name)]" -t attr -n "name" -v "pwd" \
    request.xml

Insert the PIN of the LDAP user with the following command:

$ xmlstarlet edit --inplace \
    -s "/CertEnrollmentRequest/Attributes" --type elem --name "Attribute" -v "5yD9VI" \
    -i "/CertEnrollmentRequest/Attributes/Attribute[not(@name)]" -t attr -n "name" -v "pin" \
    request.xml

Insert the request type with the following command:

$ xmlstarlet edit --inplace \
    -u "/CertEnrollmentRequest/Input/Attribute[@name='cert_request_type']/Value" \
    -v "pkcs10" \
    request.xml

Insert the CSR with the following command:

$ xmlstarlet edit --inplace \
    -u "/CertEnrollmentRequest/Input/Attribute[@name='cert_request']/Value" \
    -v "$(cat testuser.csr)" \
    request.xml

The final XML request should look like the following:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<CertEnrollmentRequest>
    <Attributes>
        <Attribute name="uid">testuser</Attribute>
        <Attribute name="pwd">Secret.123</Attribute>
        <Attribute name="pin">5yD9VI</Attribute>
    </Attributes>
    ...
    <Input ...>
        ...
        <Attribute name="cert_request_type">
            <Value>pkcs10</Value>
            ...
        </Attribute>
        <Attribute name="cert_request">

-----END CERTIFICATE REQUEST-----</Value>
            ...
        </Attribute>
    </Input>
</CertEnrollmentRequest>

Then submit the request with the following command:

$ curl \
    -k \
    -s \
    -X POST \
    -d @request.xml \
    -H "Content-Type: application/xml" \
    -H "Accept: application/xml" \
    https://$HOSTNAME:8443/ca/rest/certrequests \
    | xmllint --format -
<CertRequestInfos>
  <total>1</total>
  <CertRequestInfo ...>
    <requestID>0xfd5377c93db8f0ed016de1d688e27f7e</requestID>
    <requestType>enrollment</requestType>
    <requestStatus>complete</requestStatus>
    ...
    <certID>0x784127bb5291d998224a9426aea15c2b</certID>
    ...
    <certRequestType>pkcs10</certRequestType>
    <operationResult>success</operationResult>
  </CertRequestInfo>
</CertRequestInfos>

The certificate can be retrieved with the following commands:

$ curl \
    -k \
    -s \
    -H "Content-Type: application/xml" \
    -H "Accept: application/xml" \
    https://$HOSTNAME:8443/ca/rest/certs/<cert ID> \
    | xmllint --format - \
    > cert.xml
$ xmlstarlet sel -t -v '/CertData/Encoded' cert.xml \
    | sed 's/&#13;$//' \
    > testuser.crt

Enrollment using JSON

The enrollment can also be done manually using JSON messages.

Retrieve the template for the JSON request for the profile with the following command:

$ curl \
    -k \
    -s \
    -H "Content-Type: application/json" \
    -H "Accept: application/json" \
    https://$HOSTNAME:8443/ca/rest/certrequests/profiles/caDirPinUserCert \
    | python -m json.tool \
    > request.json

Insert the username of the LDAP user with the following command:

$ jq '.Attributes.Attribute[.Attributes.Attribute|length] |= . + { "name": "uid", "value": "testuser" }' \
    request.json | sponge request.json

Insert the password of the LDAP user with the following command:

$ jq '.Attributes.Attribute[.Attributes.Attribute|length] |= . + { "name": "pwd", "value": "Secret.123" }' \
    request.json | sponge request.json

Insert the PIN of the LDAP user with the following command:

$ jq '.Attributes.Attribute[.Attributes.Attribute|length] |= . + { "name": "pin", "value": "5yD9VI" }' \
    request.json | sponge request.json

Insert the request type with the following command:

$ jq '( .Input[].Attribute[] | select(.name=="cert_request_type") ).Value |= "pkcs10"' \
    request.json | sponge request.json

Insert the CSR with the following command:

$ jq --rawfile cert_request testuser.csr '( .Input[].Attribute[] | select(.name=="cert_request") ).Value |= $cert_request' \
    request.json | sponge request.json

The final JSON request should look like the following:

{
    ...,
    "Input": [
        {
            ...,
            "Attribute": [
                {

                    ...
                },
                {
                    "name": "cert_request",
