Using public key from WINSCP to connect to bitvise and automate sending a txt file

Hello, i created a batch file to automatically transfer a file.

I am using winscp via public key and i am trying to send the file (automated) to a bitvise server.

option batch abort
option confirm off
open sftp://username@ssh.blahblah.com -hostkey="ssh-rsa 2048 1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:1e"
option transfer binary
put -nopermissions -nopreservetime e:\BatchJobs\Files\pay\*-11111_PAY_ROLL_001-111.txt
close
exit

I keep getting stuck with enter password but we are using a public key so i don't know why its asking for a password

Please help!

To authenticate, you have to specify a private key using -privatekey switch of the open command:

option batch abort
option confirm off
#open sftp://test@blah.taxcc.com -hostkey="ssh-rsa 2048 1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:1e:"
open sftp://test@blah.taxcc.com -privatekey="e:\BatchJobs\wotc"
option transfer binary
put -nopermissions -nopreservetime e:\BatchJobs\folder\folder\*-test.txt
close
exit

I just tried this and its not working.

not authenticated or asking me for password is the error i get

Please attach a full session log file showing the problem (using the latest version of WinSCP).

i changed the fingerprint and ips

But you still have to use -hostkey to verify identity of the server.

If you are confused about all the keys, see:
https://winscp.net/eng/docs/ssh_keys
And you urgently need to update your copy of WinSCP.
