Selecting the File Transfer Integrity Algorithm preferences

When you select the File Transfer Integrity Algorithm preferences, you need to select the algorithms and set the priority of the algorithms you want to use. Some FTP servers support the optional file integrity algorithms and FTP commands used to calculate a transferred file's checksum or hash; however, each FTP server varies on the algorithms they support. Check with the FTP Administrator to confirm the algorithms that are supported on the FTP server you want to post files to.

To specify the file integrity algorithm for file transfers:

1. On the tool bar, click Options (or select Tools > Options) to open the Program Options dialog.
2. In the left pane, click Transfers > File Integrity. The File Integrity dialog opens.
3. Click the File Integrity options you want to use: CRC32, SHA1, MD5, SHA256, and SHA512.
4. Use the up and down arrows to set the preferred algorithm priority for file transfers.
5. Click Use size comparison in Transfer Integrity Checking to have the FTP client compare file size as a way to check transfer integrity if the FTP server does not support the selected file integrity algorithms.
