Perl SFTP Guide: Secure File Transfers with ftpGrid

Published {$created} by Viggo

Perl developers often need to perform secure file transfers in their applications. SFTP (Secure FTP) is the standard for encrypted file transfers, and integrating it into Perl scripts is straightforward. In this tutorial, we'll show you how to use Perl with SFTP to securely transfer files to and from ftpGrid's managed SFTP service.

What is SFTP and Why Use It?

SFTP encrypts both authentication and data transfers, making it far more secure than traditional FTP. With ftpGrid, you get enterprise-grade SFTP with automatic SSL certificate management and high availability. Learn more about managed SFTP hosting.

Perl SFTP Setup with Net::SFTP

The Net::SFTP module is the go-to choice for Perl SFTP implementations. First, install it with:

cpanm Net::SFTP

Example Perl SFTP Code

Here's a simple script to upload a file using explicit SFTP credentials to ftpGrid:

use Net::SFTP::Foreign;

my $host = 'edgeN.ftpgrid.com';
my $user = 'your_username';
my $key_file = '/path/to/private_key';

my $sftp = Net::SFTP::Foreign->new($host,
    user => $user,
    key_path => $key_file,
    timeout => 10
) or die "Could not connect: $@";

$sftp->upload('/local/path/to/file.txt', '/remote/path/on/ftpgrid');
print "File uploaded successfully!\n";

Best Practices for Perl SFTP

1. Use SSH keys for authentication (Learn how to create SSH keys)
2. Leverage ftpGrid's SFTP API for programmatic control
3. Handle errors gracefully with proper try-catch blocks
4. Monitor your usage through ftpGrid's dashboard
