Unlocking Chilkat SFTP

To use Chilkat SFTP (Secure File Transfer over SSH) you must use the unlock code for Chilkat SSH.  It should contain the substring “SSH”.  If your unlock code contains the string “FTP”, then you are using the FTP2 unlock code, which is incorrect.

The SFTP component/API is part of  the “Chilkat SSH” license:
“SFTP” is the Secure File Transfer Protocol over SSH.  It is a protocol unrelated to the FTP protocol.
The Chilkat SSH / SFTP component is used for “SFTP”.  SFTP is achieved by connecting to an SSH server at
port 22.

On the other hand, the Chilkat FTP2 components is for FTP.   FTP servers listen at port 21 (non-SSL/TLS) and port 990 (SSL).
FTP over SSL (i.e. port 990) is called “FTPS”.
