How to "test" a private key?

[Dabs]

But as you sure I will be able to spend the funds even though the privkey prints the public key? I am concerned about the bug listed here

1. You are using Bitcoin Core, not Multi-Bit
2. That bug is for a particular address, you won't ever get that address from using Bitcoin Core
3. When you see the public key and address, it should work. It will work.

When I put in

AA05F15D112414670BAD47FCCC52AD6486D5CB33BEA4463E8DFF0C5B1C1F4D1501

I get an error:

Cannot Decode! Invalid Base58 Character(s)!

That's because it isn't a base 58 check encoded private key (what you normally think of as a private key). That is the hex of the actual private key, just a really big number.

So is there any tutorial or examples can that show how to decode/encode the base 58 private keys. I am still confused.

You already have decoded the base58 check encoded private key. As I already said, you have the key in its hex format. You can convert that to decimal if you really want to. You have the key in hex so you can check whether it is greater than 0x01 and less than the large hex number I posted earlier.

Also I think the following can be helpful to look at:

What about if I use Bitaddress to generate the keys offline. Does it have that bug fixed?

If you are so interested in that particular bug you can read about it here: https://github.com/keepkey/multibit/issues/661 and https://multibit.org/blog/2015/02/02/wallet-forensics.html and it seems to me that the problem was with the user not the wallet and because he had imported private keys and messed up things in his wallet.

You are talking about generating a private key with bitaddress not a wallet with multibit

If your using bitaddress then you will be fine, but be careful if you are messing about with it yourself.
