What format is the dumpprivkey command?

Question

When I dump the private key from one wallet and try to import the private key to another wallet I get an error: Invalid private key encoding.  Is there some kind of conversion?  Is the private key encrypted?  How would I export the private key and then import it into another wallet.

Answer 1

Are these wallets on the same blockchain? Each chain has its own private key version bytes (as specified in the private-key-version blockchain parameter). If you want easy private key portability between chains you should set them up with the same value for that parameter (and assuming you want the addresses to match across chains, do the same for other address parameters as well: http://www.multichain.com/developers/address-format/)
