I installed Qtum core in my Ubuntu 16.04 server and generated my wallet, and encrypted it.
For the test purpose, I changed the password using the command like below.
I typed below command to change my password.
./qtum-cli walletpassphrasechange "oldpassphrase" "newpassphrase"
Let's say my oldpassphrase is test and my new passphrase is test"
Notice that I type the double quotation mark right after the word test
./qtum-cli walletpassphrasechange "test" "test""
This returns below line that asks me to close the double quotation mark.
So I typed " to close it.
Surprisingly, the command line has passed!
I thought the new password would be test" or test""
But they both do not work.
Can anyone guess what the new password might be?
