I know it's old, but for anyone interested, the private key is interchangeable, it's just the encoded version that's not because mainnet and testnet use a different prefix byte. See https://en.bitcoin.it/wiki/Wallet_import_format.

# signrawtransaction - Which private key from BitAddress.org?

(Asked by: username_0 on 2014-02-21)

I am trying to do multisignature addresses and when it comes time to spend the funds, I am getting stuck.

If I create a 2 of 3 multisignature address using 3 public keys that I generate locally, then dump their private keys and use those to sign and spend the funds, it works without issue.

But, when I generate public/private key pairs from BitAddress.org (Wallet Details) there are multiple types of private keys with different lengths.

* Private Key WIF 51 characters base58, starts with a '5'
* Private Key Hexadecimal Format (64 characters [0-9A-F])
* Private Key Base64 (44 characters)
* Private Key 52 characters base58, starts with a 'K' or 'L'

When I do **dumpprivkey** for one of the keypairs generated locally, it spits out a 52 character key. So I thought maybe the 52 character base58 private key was the one I should enter, but it returns "Invalid Private Key".

The key that **dumpprivkey** spits out does not follow any of the rules of any of the above private keys provided by BitAddress.org generation. So how do I generate this private key that I can use in **signrawtransaction** ?

I want users to be able to generate and supply their own private keys for a multisignature escrow, so generating the addresses locally is not an option.
