IBM Cognos 8 cryptographic services use a specific .jar (Java Archive) file, named bcprov-jdknn-nnn, that must be located in the JVM environment used by your application server. This file provides additional encryption and decryption routines that are not supplied with a default JVM installation. To ensure security, the encryption file must be loaded by the JVM using the Java extensions directory.
Ensure that the JAVA_HOME environment variable is set to the JRE location.
For example, to set JAVA_HOME to a JRE that you are already using, the path is Java_location/bin/jre/version.
Copy the bcprov-jdknn-nnn.jar file from the c8_location/bin/jre/version/lib/ext directory to the Java_location/jre/lib/ext directory.
