I am looking for an FTP client for Mac that can encrypt files so account provider wouldn't read my data.

Is it even possible?

I am not looking for encrypted transfer, I am looking for encrypted files on the server so only with password you would be able to read them.

You cannot encrypt files while they're being transmitted with FTP alone. FTP was made for transmitting files quickly, so there are no methods to do a one-way encryption on a file that you send. Only full encryption of the FTP transfer is possible, but that would leave you with unencrypted files on the remote server.*

If you want to store encrypted files on the remote server, you should encrypt them before sending, e.g. with OpenSSL or any other encryption method like putting them in a TrueCrypt container.

* The only way to have an encrypted FTP transfer itself is to do it over SSL, which is called FTP-SSL or simply FTPS. However, in order to use it, the remote FTP server needs to support this. All major FTP clients for OS X (including Cyberduck and Transmit) support FTPS.
