I am in the planning process of implementing SFTP functionality within our product. Currently it only support FTP (using NETTALK), but I would like it to have SFTP as well, due to increasing customer demand.
All my search leads me to Klarisoft (using SocketTools). What I like about this is, it uses native windows library and NOT ActiveX controls.
If anybody out there know of any other options, please let me know.
Thank you
Mathew
I can 100% recommend LibCurl from Mike as per the URL in the previous reply.
Works perfect.
Thanks guys… Let me have a play with it.
Hi Mathew,
I know you’ve said NOT ActiveX control but I think its still worth mentioning the Chilkat ActiveX control.
We support it in Clarion (c6 - c10, ABC + Legacy) and it works with RegFreeCOM so there are no worries about access rights on any PCs. We’ve had it on a test for 5 days solid querying and updating Xero Accounting and it didn’t miss a heartbeat - Very stable.
The Chilkat ActiveX control provides LOTS of communication functionality (98 separate libraries) including (but not limited to):-
AuthAzure
AuthGoogle
Crypt2
Email (inc Imap)
HTTP
Java Web Tokens
Json
OAuth 1 and 2
Pfx keys
Rest
FTP and SFTP
SCP and SSH
Rest
StringBuilder
Socket
XML
Zip

We’ve create a wrapper template for this control and is being updated constantly. As well as covering the bases classes, we’re also adding ‘Task’ classes to make selected tasks even easier. Eg:-
Dropbox
Google
Paypal
QuickBooks Online
SMS
Xero Accounting

Any question - just ask 
Thanks,
