I have implemented some algorithms in a new java-provider and want to test them using the security provider of java: Security.addProvider(new RSAPKCS1Provider()); Provider p = Security.getProvider("MyNewProvider"); Getting the generator for the keypair ist working fine: KeyPairGenerator generator = KeyPairGenerator.getInstance("RSA", "MyNewProvider"); But using Cipher cipher = Cipher.getInstance("RSA", "MyNewProvider"); throws the exception "The provider MyNewProvider may not be signed by a trusted party" More>>

I have implemented some algorithms in a new java-provider and want to test them using the security provider of java:

			

			Security.addProvider(new RSAPKCS1Provider());
			

			Provider p = Security.getProvider("MyNewProvider");

Getting the generator for the keypair ist working fine:

			

			KeyPairGenerator generator = KeyPairGenerator.getInstance("RSA", "MyNewProvider");

But using

			

			Cipher cipher = Cipher.getInstance("RSA", "MyNewProvider");

throws the exception

			

			"The provider MyNewProvider may not be signed by a trusted party"

Can I use the functionality of the security provider without signing my jar-file? How can I disable this check on my local PC?

thanks florian

You can actually replace an original j2sdk1.4.2jrelibjce.jar by 3rd party clean-room JCE implementation, e.g. BouncyCastle. From other hand it is not that difficult to get a certificate to sign your provider for using with Sun's JCE. Complete instructions are in "How to Implement a Provider for the Java Cryptography Extension" document.
