Re: What is the difference between ftp encryption types SSL, TLS, SFTP and SSH ?




Marcus Mender skrev:
I have seen a couple of different encryption types for ftp connections:
TLS
SSL
SFTP
SSH
Ok, provided an ftp server offers all these types: which type should I
choose
to setup the ftp server or to select from the ftp clients view ?
Is the security for all these types similar and the difference refers
only different protocols?
What are the pros and cons ?
Marcus


Briefly:
SSL is an encryption type.

No. It is a communications protocol which employs encryption as part of
its operation.

SSH is remote login using SSL to get encrypted command line access
("secure telnet")

No. The SSH protocol is not, and does not use, SSL at all.

SFTP is file transfer using SSL

No. SFTP (typically) runs over SSH which (v.s.) is not SSL.
