Re: Re: Re: Perl & Java -- Can they keep a secret?

The only problem was my inability to locate an equivilant to Digest::MD5 for Java that didn't involve adding other 'providers.'

You don't have to register a new security provider just to use MD5 Digests. Take a look at this method in the MessageDigest class pay particular attention to the "Note: the provider doesn't have to be registered." part.

It still requires the provider's presence... and it is my understanding that the sun provider is the only one included in the core Java dist. My code doesn't have bugs, it just develops random features. Flame	[reply]

I don't think so. I haven't dealt with crypto providers much, but as i understand it the whole point of the two different "getInstance" methods is that in one case you are saying "get me an instance from whichever provider is configured in my JVM for "foo". In the other case you are saying "get me an instace from this provider, right here, this one, the one i'm passing you" -- all you have to do is make sure you have a constructed Provider object. Even if I'm wrong, you can still modify the security providers list at run time... that's what Security.addProvider and Security.insertProviderAt are for.	[reply]
