WD2025 FTPConnect() returns -1

Hello all
Windev code issue:

FTP connection code that works correctly in versions 24 thru 29 (2024) returns a -1 (error) in v30 (2025).

Protocol is SFTP.

Sample code (site is trusted):

FTP.IgnoreError = ftpIgnoreExpiredCertificate + ftpIgnoreInvalidCertificate + ...
ftpIgnoreInvalidCertificateName + ftpIgnoreRevocation
nResult is int = FTPConnect(sXURL,sXCode, sXPassword,22,ftpPassiveMode) // WD2025 returns -1 here

Has anyone experienced this or has a solution? I have raised a query with PC Soft Technical support, no answer just yet (early days).

Regards
Mike

Did you read the help? "The details of the error are returned by ErrorInfo with the errCode or errMessage constant.
If an identification error occurs, ErrorInfo with the errCode constant returns the ftpErrorAuthentication constant."

Hi MiellesMain, thanks for your helpful comments. After following your suggestion I obtained an error code 100002.

I have also had a reply from PC Soft which advises that "Your FTP server currently using DSA encryption, which has been deprecated for years. OpenSSH has/will stop support 'early 2025'." (The server has been in existence a long time).

They also provided a detailed error:

> - DSA: `ssh-dss` hostkeys.
> You can enable it now with `-DLIBSSH2_DSA_ENABLE`.
> Disabled by default in OpenSSH 7.0 (2015-08-11).
> Support to be removed by early 2025 from OpenSSH.

Maybe this suggests a workaround?

But in any case, it seems I will need to talk to the FTP server owners.

Regards
Mike

PC Soft have now released an update for this issue, which allows my FTP connection to work. I presume they have re-enabled DSA keys in their program, perhaps after many protests.

Hello,

we're having a related issue, Windev's sftp is using deprecated SSL-ciphers by default.

Any idea how to mitigate this?

Kind regards
Steffen

Hi Steffen

Possibly this, prior to ftpConnect():
FTP.IgnoreError = ftpIgnoreDeprecated?

Hi Mike,

thanks for putting replying :-)

I believe the remote sftp-server is denying the connection. Is your solution surpressing the error itself or forcing windev to use non.deprecated ciphers?

Kind regards
Steffen
