To verify the integrity of a file via SFTP, you can use one of the following methods:
1. Checksum validation: Use a checksum utility to generate a hash value for the file on the remote server, download the file to your local machine, and generate a hash value for that local file as well. Compare both hash values to ensure they match, which indicates that the file has not been corrupted or modified during the transfer.
1. Compare file sizes: Check the file size of the remote file and compare it to the file size of the local file after downloading. If they match, it indicates that the file has been successfully transferred without any data loss or corruption.
1. Use SSH protocol: SFTP uses SSH for secure file transfer. You can use SSH to verify file integrity by accessing the remote server via SSH, navigate to the directory where the file is stored, run a command to generate the hash value for the file, and compare it with the hash value generated for the local file.
