An install guide can be found here: install guide

I recommend installing via the topic: Installing the Provider Statically

⚠️ The BouncyCastle install guide just doesn't tell you enough

Here, I'll elaborate on the BouncyCastle install instructions:

  • Step #1 Download the BouncyCastle jar file

  • Step #2 You have to edit the file: $JAVA_HOME/jre/lib/security/java.security

    • You must EDIT AND INSERT the following line:
    security.provider.{N}=org.bouncycastle.jce.provider.BouncyCastleProvider

      - MORE ABOUT EDIT AND INSERT
  - GOTO middle of security file and look for something like
  ```
  security.provider.1=sun.security.provider.Sun
  security.provider.2=sun.security.rsa.SunRsaSign
  security.provider.3=sun.security.ec.SunEC
  security.provider.4=com.sun.net.ssl.internal.ssl.Provider
  security.provider.5=com.sun.crypto.provider.SunJCE
  security.provider.6=sun.security.jgss.SunProvider
  security.provider.7=com.sun.security.sasl.Provider
  security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI
  security.provider.9=sun.security.smartcardio.SunPCSC
  security.provider.10=apple.security.AppleProvider
  security.provider.11=org.bouncycastle.jce.provider.BouncyCastleProvider
  ```
  
  - replace {N} with your next security provider number
  - security.provider.11 has been used for the example seen above

  • Step #3 You may need to restart your computer to restart Java as BouncyCastle should now be installed

⚠️ If when encrypting or decrypting you get an error of something like "no suitable crypto library found" then BouncyCastle is NOT installed correctly

Another possible error indicated Bouncy Castle is not properly registered as a provider:

Could not find a suitable javax.crypto provider for algorithm 1.2.840.113549.3.2; possible reason: using an unsigned .jar file

Here is more generic variation on how to install JCE Providers
