JCE cannot authenticate the provider (WebSphere (, IBM java 191)

User_381UP Member Posts: 1 Green Ribbon

Hello Java Community,

We got our first JCE code-signing certificate from Oracle in 2018.

One of our client has the following problem:

they need to run the JCE provider on WebSphere (, IBM java 191), which does not accept this certificate and return JCE authenticaton error (java.lang.SecurityException: JCE cannot authenticate the provider).

Our tests show that newer version of the appserver WebSphere accepts the certificate, but for our client upgrading is not an option.

Can we get a code-signing certificate with an older issuer somehow, that may be possibly accepted by WebSphere (, IBM java 191)?
