SFTP support in FreePascal applications
« on: January 22, 2016, 10:33:29 pm »
Hi,

I have noticed that there does not seem to be support for SFTP either in Synapse or in lNet, nor in any other free library.

From what I could find, the only FreePascal library that supports SFTP is Devart SecureBridge Components, but it's a commercial product.

Isn't there really any free SFTP library in the FreePascal ecosystem?

Thanks

Yes, I'm using libssh2 from synapse for that purpose

Does it work well?
Is it easy to set up and use?
Any good tutorials / examples?

I'm affraid you have been misinformed. Indy 10 support secure client and server FTP components.

   http://www.indyproject.org/kb/index.html?howdoiuseftpwithssl.htm

Use the Indy 10 SVN URL for the latest code that works 100% with FPC 2.6.4 and FPC 3.0.

SFTP is different from FTP+SSL (which is called FTPS)

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

Yes, it's pretty easy to use (you have C examples on net for sftp, they're easy to understand and translate to pascal).
Thaddy provided link for sources for you :)

I believe Indy supports both.

This is incorrect, Indy supports FTPS, not SFTP, see https://github.com/IndySockets/Indy/issues/253

It's FTP over SSH, not ssl...
FPC supports both.
Here's a link using synapse http://synapse.ararat.cz/files/contrib/sftp.zip

That one requires cl32.dll (CryptLib) which you might not be able to distribute with your program depending on the license.

But the same source can be made to work with libssh2 (which I think has a more liberate license policy).

vicot was referring to FTPS, which is indeed FTP over SSL/TLS, and is what Indy supports.  SFTP is FTP over SSH, which Indy does not support at this time.
