Hi there,

Could anyone explain me how to export and import bitcoin's private keys in bitcoin core. I have exported private keys, it's a text file and have something like:

# Wallet dump created by Bitcoin v0.16.0
# * Created on 2018-10-08T10:01:00Z
# * Best block at time of backup was 544879 (00000000000000000010c6fe1edd3f236745b6af51929969bdaba2d59200dcc5),
#   mined on 2018-10-08T09:51:59Z

 "# extended private masterkey: "
2018-04-26T17:08:10Z change=1 # addr= hdkeypath=m/0'/0'/699'
2018-04-26T17:08:10Z change=1 # addr= hdkeypath=m/0'/1'/947'
2018-04-26T17:08:10Z change=1 # addr= hdkeypath=m/0'/0'/86

This is a long list which goes on about four thosand lines. Then I see:

0 script=1 # addr=
0 script=1 # addr=

This goes till some eight thousand lines and the file end with # End of dump

Please help to understand all this messy thing.
