Hi,
I am having authentication issue with the script file run by SSIS service account. The open command in the script file has -hostkey provided. The outside-profile was created from WinSCP GUI with my login credential. I have no problem connecting to the remote site from WinSCP GUI and running the script with my credential. When SSIS uses my script, it is get authentication failed. The SSIS is using a Windows service account not my credtential.

From the log with my credential, I see "User name: outside-profile (Password: Yes, Key file: No)" password is Yes. I also see "Using stored password.". From the SSIS log, I see "User name: outside-profile (Password: No, Key file: No) and do not see "Using stored password". A hostkey is provided in the script file like 'open outside-profileg@sftp.outside.com -hostkey="ssh-rsa 2048 fe:b6:a7:24:e1:6e:a8:d2:2d:a2:3a:77:b2:c5:b0:f9"'. Did I miss anything? Any suggestion?

Below is the log file with authentication failed.

The -hostkey switch has nothing to do with authentication.
Make sure you undertstand, what different keys in SSH do:
https://winscp.net/eng/docs/ssh_keys

Your script does not include any password or private key.

If it works outside of SSIS, it's most probably because you are authentication with a private key loaded in Pageant (although you do not mention that).
SSIS runs in a different Windows session. It cannot access Pageant in the user session. Pageant is not intended for automation anyway.

Explicitly specify your private key in the script.

If the above is not true or doe not help, see
https://winscp.net/eng/docs/faq_scheduler

Or at least post a log file on working session for comparison.

Hi Martin,
You are correct. How can I grant access to SSIS to use my profile? What do I need to provide in the script to let it refers to my profile?

Below is the log session which I could access to the remote site per your requested:

You have a stored site named outside-profile@sftp.outside.com in your local account mydomain\hbrandon.

Your script uses that stored site, which includes a password.

SSIS does not have an access to that.

Solutions are covered here:
https://winscp.net/eng/docs/faq_scheduler
(I wanted to point your there in my previous post, but I've used a wrong link, corrected now).

Basically use:
open sftp://outside-profile:password@sftp.outside.com -hostkey="ssh-rsa 2048 fe:b6:a7:24:e1:6e:a8:d2:2d:a2:3a:77:b2:c5:b0:f9"

Actually, had you used the latest version of WinSCP (what you should do anyway), it would warn you and suggest you to use the above command, instead of relying on stored site.
