Java Bitcoin Utils

I'm looking for a simple library to handle basic bitcoin related calculations such as
- generating private keys
- calculating public keys
- calculating bitcoin addresses
I'm not looking for any actual bitcoin network interaction. I'm looking at bitcoinj opened but before I slim it down to the classes that are relevant to me I figured I'd ask and see if this is something that's already available.
Whoever mines the block which ends up containing your transaction will get its fee.

I wrote this awhile ago, and it does all that, but does require the use of the bouncy castle dependencies

bitcoinJ is very simple for that:
Code:
new ECKey().toAddress(NetworkParameters.prodNet())

Just take the ECKey, Address and VersionedChecksummedBytes classes from bitcoinj and you have what you need. They don't depend on other parts of the library.

So you have a choice:
