Can't connect to SFTP server with some SFTP client software

[FTP]

Some old SFTP client software (like Putty v0.60, FTP Rush v2.x) can't connect to WingFTP due to the SFTP/SSH algorithms, you can add a few SFTP algorithms to solve the problem:

1. Append an algorithm "diffie-hellman-group1-sha1" to the option "Server > Settings > General Settings > Security > SFTP Key Exchange Algorithms".
2. Append an algorithm "hmac-sha1" to the option "Server > Settings > General Settings > Security > SFTP MAC Algorithms".
3. Append an algorithm "ssh-rsa" to the option "Server > Settings > General Settings > Security > SFTP Host Key Algorithms".
