          If you haven't deleted the file ~/.ssh/id_rsa.old, that's your old key without passphrase ("unencrypted").



          Otherwise, to remove a passphrase from the keyfile just use the command



          openssl pkey -in ~/.ssh/id_rsa -out ~/.ssh/id_rsa_unencrypted



          You will be prompted for the passphrase.



          EDIT: changed filenames to be more clear.
