Enable checksum on FileZilla server

Question

How can I enable checksum on the FileZilla server? I want to compare files after downloading on my Android device via FluentFTP library.

The following checksum FTP commands are supported by this library: MD5, XMD5, XCRC, XSHA1, XSHA256, XSHA512.

Answer 1

In the FileZilla Server installation folder locate file FileZilla Server.xml. That's typically:

C:\Program Files (x86)\FileZilla Server\FileZilla Server.xml

In the file, locate the <Settings> tag and within it find Enable HASH item and set it to 1:

    <Settings>
        ...
        <Item name="Enable HASH" type="numeric">1</Item>
        ...
    </Settings>

Restart the server.

Note that this enables a support for HASH command. While it's not in the list in your question, FluentFTP supports it too.

The FileZilla FTP server supports SHA-1, SHA-512 and MD5 hash algorithms with the HASH command.

All the EXPERIMENTAL BUILD ... Implementing draft-bryan-ftp-hash-06 header is an indication that the HASH command is enabled. Also note the HASH SHA-1*;SHA-512;MD5 in the FEAT command response.
