Hi Vidya

Q1 ) Is there a difference between an SFTP server & an FTPS server?

Yes, SFTP and FTPS are completely different.

SFTP is a technology that is built on Secure Shell (SSH). It is not based on SSL and is not a secure extension of FTP. Although the commands are superficially similar to FTP, the way in which they implemented is completely different.

FTPS is a secure extension of standard FTP, which works over SSL. It basically just takes the standard FTP protocol and uses SSL to encrypt communications.

Q2) Can an SFTP server have a 128-bit explicit SSL encryption?

SFTP does not use SSL. It uses SSH. Yes, it can have 128 bit encryption.

Q3 ) Can edtFTPj/SSL handle an SFTP server with 128-bit explicit SSL encryption?

We are intending to release edtFTPj/PRO, which supports both FTPS and SFTP, on Friday 22/4/2005. Initially, the SSH functionality will only be a beta, but it should be up to production quality within a few weeks. It supports 128-bit encryption.
