Create a self-signed certificate

Create a self-signed certificate. WebSphere Application Server uses the certificate at runtime during the handshake protocol. Self-signed certificates are located in the default keystore.

We must create a keystore before creating a self-signed certificate.

Alternative Method: To create a self-signed certificate using the wsadmin tool, use the createSelfSignedCertificate command of the AdminTask object. See PersonalCertificateCommands .article.

Certificate aliases with embedded quotes in them can cause issues when the runtime attempts to use them. Do not use embedded quotes in a certificate alias.

Tasks

1. Click...
   Security | SSL certificate and key management | Manage endpoint security configurations | {Inbound | Outbound} | ssl_configuration | Key stores and certificates | [keystore ] | Additional Properties | Personal certificates | Create a self-signed certificate

2. Type a certificate alias name.

   The alias identifies the certificate request in the keystore.

3. Type a common name (CN) value.

   This value is the CN value in the certificate distinguished name (DN).

4. Type the validity period

   The default validity period value is 365 days.

5. We can configure one or more of the following optional values:

   1. Optional: Select a key size value. The default key size value is 2048 bits.

   2. Optional: Type an organization value. This value is the O value in the certificate DN.

   3. Optional: Type an organizational unit value. This organizational unit value is the OU value in the certificate DN.

   4. Optional: Type a locality value. This locality value is the L value in the certificate DN.

   5. Optional: Type a state or providence value. This value is the ST value in the certificate DN.

   6. Optional: Type a zip code value. This zip code value is the POSTALCODE value in the certificate DN.

   7. Optional: Select a country value from the list. This country value is the C= value in the certificate request DN.

6. Click Apply.

We have created a self-signed certificate that resides in the keystore. The SSL configuration for the WAS runtime uses this certificate for SSL communication. Extract the signer of the self-signed certificate to add the signer to another keystore.
