bouncycastle provider can't find classes needed for algorithm

Question

I\'m trying to use bouncycastle to encrypt a file using a public key. I\'ve registered the provider programatically:

Security.addProvider(new BouncyCastlePro         


        

Answer 1

You have a BouncyCastle Security provider installation problem, you need to either

• Add BouncyCastle to the JRE/JDK $JAVA_HOME/jre/lib/security/java.security file as a provider (be sure that you add it to the JRE you use when running, eg. if you have multiple JRE's/JDK's installed)

eg.

security.provider.2=org.bouncycastle.jce.provider.BouncyCastleProvider

(and renumber the security providers below it - don't put it as the highest priority provider).

• or you can add BouncyCastle programmatically, as you were trying to do above, but in this case the security policy $JAVA_HOME/jre/lib/security/java.policy should be "unlimited" (you can probably download an unlimited policy file from the Java homepage).
