The library consists of three JAR files located in the Bin folder of the library distribution ZIP file:
1) bcpg-jdk14-145.jar
2) bcprov-ext-jdk14-145.jar
3) pgplib-2.5.jar
They must be copied, referenced and distributes with your software in order the library to work.
Note: If you already have some of the BouncyCastle JAR files in your project (for example another library already depends on them), please refer to section BouncyCastle compatibility
