The LiveCode engine can already do secure communication using SSL
(Secure Socket Layer). It would *probably* be possible to use "secure
socket" to implement FTPS (FTP over SSL) in scripts, without any engine
changes (i.e. in libUrl).
SFTP is not FTPS or FTP. It's an unrelated file transfer protocol that
runs over Secure Shell (SSH). It would be a relatively large project to
add it to the engine, because we would be able to use the existing
secure network communication support in LiveCode, and we wouldn't be
able to use *any* of the existing FTP support in LiveCode.
The regular requests for SFTP support are noted and SFTP support is on
our internal list of feature requests -- indeed, I was recently
discussing it with Mark Waddingham. However, it will be a large project
that will involve writing and thoroughly testing a lot of new,
security-critical code. When we have the resources available to
implement it, it will therefore very likely be introduced an extension
available to LiveCode Business customers.
In the meantime, you could work around the absence of SFTP support
(while maintaining server security) by creating an HTTPS web service
that allows uploads only by authenticated clients which provide a valid
API token.
One thing I don't understand - please can you explain why you can't just
do your uploads by shelling out to the "scp" or "rsync" commands?
