I want to test the sftp component from Chilkat so i downloaded the chilkatPerl.ppd component for actve state perl today.
Trying the sample from Chilkat fails immediately after the connect.
It returns with DSS signature verification failure.
Can you point me to the right track about whats wrong?

The new builds are available here: http://www.chilkatsoft.com/perl.asp (or you can re-install using ppm) If using ppm, make sure to remove the existing package first before re-installing.

Please let me know if you see any problems.

This was caused by a bug in the version of the MinGW gcc compiler used for Perl ( http://sourceforge.net/projects/perlmingw/files/Compiler%20for%2064%20bit%20Windows/ )

The problem has to do with the intrinsic _lrotl and _lrotr functions, which are used in the SHA1 computations on Win32 builds. These intrinsic functions are not used internally by Chilkat for non-Windows operating systems. The internal fix is to avoid using _lrotl/_lrotr and instead use #define's for the bit rotation operations.

Here are more details about the bug:
http://sourceforge.net/p/mingw-w64/mailman/message/32652852/

I'll post here when a new build has been uploaded.

I just downloaded the build 9.5.0.54. It works!
Many thanks for your efforts, i'm surprised for getting a bugfix over the weekend, that's great!
I'll go and get a commercial license for the company i work for.

That's very strange..

Try setting the sftp.HostKeyAlg = "RSA" (see http://www.chilkatsoft.com/refdoc/perlCkSFtpDoc.html#prop15 )

I'll try to reproduce the problem, but I suspect I won't be able to..

I did and tried RSA but this fails either with RSA signature verification failure. Please see the output below.

Interesting, I tried the ActiveX component and used the VB sample from Chilkat. This one works no problem!

I tried different SSH Server, all the same problem. Think it is easy to reproduce just use an recent Linux/Debian SSH Server.

Thanks, I'll give it a test with ActiveState Perl on Windows. Assuming you're using Perl 5.20 or 5.22, then it means the native Perl module is compiled with MinGW (gcc 4.6.3). I wonder if it's some sort of compiler issue? If I can reproduce the problem, I'll see if compiling with lower optimization makes a difference..

I have download 9.5.0.54 Win32 and Win64 versions of the Perl modules and the test.pl is reporting 9.5.0.53 for both. Is there an issue with the packages?

Use the ppm install method and now showing 9.5.0.54. Note some install issues:
