Combine Multiple PKCS12's into a Single Java KeyStore

See more Java KeyStore (JKS) Examples

Combines multiple PKCS12's into a single Java KeyStore (JKS) file. To combine multiple PKCS12 files into a single JKS, simply load each PKCS12 into a PFX object, add it to the Java keystore object via the AddPfx method, and then finally write the Java keystore at the very end. Android™
