Reading an X.509 certificate with Java

Question

I am trying to use Java to read a certificate that I received from an external party. The code is throwing the following error:

java.lang.RuntimeExcep

Answer 1

Try to type this using openssl, and then import the result:

openssl x509 -outform der -in certificate.pem -out certificate.der

or use the Java Bouncy Castle functionality in the lightweight API:

You may encode the result again and then use the default CertificateBuilder in Java to get a JCE defined certificate.
