Import Private key(s)
The last command unlocked your wallet temporarily for 120 seconds, during which time you must import your private keys. Since private keys can be as important as your passphrase, you may want to use the same techniques as above to prevent their being recorded in bash history (bash variable or space before the command):
(space)bitcoind importprivkey "5yourveryveryveryverylongprivatekeystring" "my-new-key" # "my-new-key" is a label for the key/address pair and is optional
The importing process is now started. Bitcoind will rescan the entire block data to ensure this key has not been used before. This process will take from one to two minutes, depending on your CPU performance. DO NOT abort it before finishing!
I have stupidly aborted an importprivkey operation.
Now I cannot add the private key. Returns error: {"code":-4,"message":"Error adding key to wallet"}
Is my wallet now damaged? How can I fix this?
