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
