Subject alternative names

This article describes how to add a subject alternative name (SAN) to a secure Lightweight Directory Access Protocol (LDAP) certificate. The use of the SAN extension is standard practice for SSL certificates, and it’s on its way to replacing the use of the common name. Subject Alternative Name (SAN) is an extension to X. Common Name (CN) is set to only one of both: CN=domain. Invalid self signed SSL cert - Subject. SSLHandshakeException: No subject.

CertificateException: No subject alternative names present then basically it means that your JKS file is missing the required domain on which you are trying to access the application. The subject name of a certificate is a distinguished name (DN) that contains identifying information about the entity to which the certificate is issued. However, DigiCert Wildcard Certificates allow you to include SANs in your certificate as a workaround.

Let’s take a look at a real-time example of skype. SAN in a single certificate. With a subject alternative name you can create cert that is valid for both domainand domain2. Usually most external cert providers limit the amount of subject alternative names.

CA uses this construct when issuing SSL server certificates. It contains the domain(s) for which this certificate is issued. With Multiple Domain Certificates you can secure a larger number of domains with only one certificate.

There are two ways that you can add the alternate host name binding for certificate authentication. The question has been answere but I still struggled with getting this into an elegant and useful form to automate CSR generation. The one liner is nice so I incorporated it into a routine that allows the subject alternative names as command arguments rather than values in a file also the flexibility to SAN or not to SAN. A few days ago I saw (and answered) a question related to how to create a SSL server PSE with SAN. Since via STRUST it is not possible, the alternative is using the command line tool, sapgenpse.

But when a “just make it work” approach works its way into certificate subject name alternative (SAN) provisioning, I think it’s time to take a pause and review what exactly is at stake. This enables us to publish multiple DNS names using one SSL Web Listener. Change alt_ names appropriately. Existing practice, be damned.

These certificates are often used by businesses that maintain related websites under different domain names. Let’s execute the command with the relevant arguments. Hello All Can someone please help me with the following question.

I have a certificate flat file so I used the following. NET type in PowerShell to get it into an object. CN is only evaluated if subjectAltName is not present and only for compatibility with ol non-compliant software.

X509Extension objects in the PowerShell Certificate Provider. First you can get the cert you want to view. OpenSSL CSR with Alternative Names one -line. Some certificate authorities will allow you to update a certificate to add new SANs to it, but this always requires an updated CSR. This may be caused by a misconfiguration or an attacker intercepting your connection.

The common name can only contain up to one entry: either a wildcard or non-wildcard name. It’s not possible to specify a list of names covered by an SSL certificate in the common name field. Using a SAN certificate Is more secure than using a wildcard certificate which Includes all possible host names In the domain.

Typically, values include server names (for example, Mailbox01) and FQDNs (for example, mail.contoso.com). You can specify multiple values separated by commas. You will need something in the CN fiel for example, ise.

DNS SAN entries (as you have listed above).
