The User Certificate dialog is where you can re-generate and export a
security certificate for this OPC UA user.
This certificate is consumed by the OPC UA server when the
authentication type on the OPC UA server is set to
Username/Password logon.
- Name
- The name of the certificate is generated with the user account
name prepended to
OPC UA Certificate.
- Valid Until:
- The expiration date of the certificate. This is auto-generated
for the certificate.
- Thumbprint
- The certificate's hash algorithm identifier. This is
auto-generated for the certificate.
- Generate
- Generates a new certificate. The expiration date and thumbprint
change. The new certificate is added to the store and associated with this
user.
- Details...
- Displays the details of the certificate. This information is
generated by the creation of the certificate and cannot be changed without
generating a new certificate.
- Export Certificate
- Select the type of certificate to export.
- Public key (.cer) - is a certificate
which uses a digital signature to bind together a public key with an identity.
The certificate can be used to verify that a public key belongs to an
individual.
- Private + Public key (.pfx) - is a
file that stores an SPC, or Software Publisher Certificate, and uses encryption
to determine who has access to system programs or even the system itself. A
certificate authority provides your SSL Certificate file (public key file). You
use your server to generate the associated private key file as part of the CSR.
A CSR is an encoded file that provides you with a standardized way to send your
public key along with some information that identifies your company and domain
name to a certificate authority. Before you can order an SSL Certificate, you
must first generate a CSR (Certificate Signing Request) for your server.
The Private + Public key needs a password before
you can export it. Enter and confirm a password for the certificate. This
password will be required when you store the certificate with the OPC UA
server.
- Export
- Exports the certificate as one of the following formats:
- .cer file (Internet Security Certificate File format)
- .pfx file (Personal Information Exchange format)
