BlogsCloudTechHow does Encrypted File Transfer works? Detail Explanation.

Encrypted file transfer is a technique used to secure data and secure files in transit. This technique works when we need to send a file from one location to another through an external network or the Internet. As we know, sending files on an external network is not safe or can be hacked. We might have heard about security breaches that occur every day and leads to losses for many businesses and individuals.

Businesses today, digitally need to share large files and often deal with security breaches. An encrypted file transfer file is encrypted by using algorithms. The file key is only shared with the sender and recipient to secure the file transfer. In this article, we will discuss how encrypted file transfer works.

What is Encrypted File Transfer?

Encrypted file transfer is nothing but the data encryption process before sending or receiving files on an external network or Internet. It is a necessary process to secure files from hacking. The file is encrypted using different algorithms and generating the file key in this process. This key is shared with the sender and recipient to secure the file transfer connection.

According to Technopedia, “Encrypted file transfer is the process of encrypting a file before transmitting it over a network, Internet and/or remote server. It is done to secure a file and hide its content from being viewed or extracted by anyone except the receiver or sender.”

Encrypted transfer can protect the information from potential hackers. Here in this process, the data sent is encrypted, and it will remain the same in transit that no one can read it. But, once the recipient receives the file, it will convert into readable format. The data is only accessible to those who have the file key.

Send files securely with encryption is now becoming very important as the number of potentials hackers are increasing day by day. Encrypted file sharing service helps businesses to protect data from the hacker. To access data from encrypted files, the hacker needs to break the server, and also he will need to find the file key to decrypt the data.

How Does It Work?

Everyone knows that the Internet is a scary place for any business. Hence, most people pay attention to the best solutions for protecting their data. Encryption is one of the best practices to secure your data. Encrypted file transfer has three options, as mentioned below:

  • FTPS (File Transfer Protocol Secure)
  • SFTP encryption (SSH File Transfer Protocol) and
  • HTTPS (HTTP Secure)

With Secure file transfer, you can move data with any size, volume and complexity securely and efficiently from anywhere. However, the secure file transfer will help administrators quickly check and review the transfer process and save time for other business processes.

The file transfer protocols SFTP and FTPS help businesses secure their information with algorithms and safeguards such as keys and passwords. Encryption while transferring files from one server to another is not enough. But to protect your data, you will also need to encrypt it when it is at rest on your home server. Hence, encryption will add extra protection and helps from hacking.

End-To-End Encryption Options

FTPS (File Transfer Protocol Secure) is the widely used or implemented file transfer encryption option. FTPS utilizes SSL encryption for its implicit and explicit notes. In FTPS implicit encryption, the server and the client can institute SSL before transferring the data. But in precise SSL, both client and server will decide the standard of sessions that occur on a single port.

SFTP encryption (SSH File Transfer Protocol) requires only one port, and it is the most straightforward option of file transfer protocol encryption. In this FTP option, an encryption Cipher helps protect data exchanged between the client and server. It will also safeguard public and private keys. Another data protection is from public-key authentication.
FTPS and SFTP use encryptions for data protection within servers, and the HTTPS is for human-based file transfer. Websites use HTTPS for security purposes. Moreover, HTTPS helps secure data sent between browsers and website people visits.

The benefit we get from all these three encryption protocols is data protection. Moreover, businesses are using these options for information security purposes.

Top Secure File Sharing Services

Here we will discuss some private file sharing options:


Onion share is one of the popular file-sharing services. It allows you to share files privately with security through any network. Here, in this open-source platform. Audiences create an onion address to visit browsers and access information for transferring.


A file hosting platform Lufi is, helps us to share files easily. Sending a file through Lufi, first, you will need to upload those files on Lufi. After uploading, Lufi encrypts those files before sending or uploading to the server. Further, the IT administrator won’t be able to read those files. Only he can see the file name, size, and so on.


Keybase is one of the secure file sharing and messaging platforms. It uses end-to-end encryption to secure your files and will make sure to send those files to the correct recipient. Public key cryptography helps you to secure your message and make it private. KeyBase is the best platform for businesses and families as it protects your files or chats from hacking.


With the help of Datash, you can send or receive files through any browser between any device. You do not need to register its interface. Datash uses 1024-bit public or private key encryption to secure the data files. Moreover, it encrypts the files with the public key before sending them to the recipient.


Tresorit is a free and advanced file-sharing platform for businesses. To secure your confidential files, you can use tresorit. With tresorit, you can control your data files even after sending them to another person.


SafeNote is the best solution to send your files temporarily. This platform is free and provides privacy and simplicity to your data file. Here you can upload your files and generate a link. You can share this link with them with whom you want to share files. When the recipient downloads the file, you can delete those files.


An open-source web platform FilePizza uses WebTorrent and WebRTC to share files online. However, it does not require uploading files on a third-party server. It uses in-browser P2P (Peer to Peer) file transfer.

Features of the Best Secure File Transfer Solution

Today, many businesses face different security threats in fast-moving environments. So, they need a secure file transfer solution to protect and secure their confidential business data. Here are some essential features of the best secure file transfer solution.

Data security:

Business data in transit or left unprotected can lead to a data breach. Hence to secure the data, end-to-end encryption is necessary. It will be only possible with encrypted file transfer, a secure file transfer process for data security.

Automated processes:

File transfer with automation helps ensure accuracy, and it will save your time. Automated process with secure file transfer solution protects your confidential information from hacking. With fast file transfer, you can schedule your file transfer with proper encryption.


Businesses need to meet government or industry-regulated compliance to share their files—the compliances such as GDPR, HITECH, SOX, PCI, etc. With Secure file transfer, you can maintain these compliance rules by controlling and monitoring capabilities.


In conclusion, encrypted file transfer will help you share data efficiently and securely. The IT administrator can quickly view or update the transfer activity with a secure file transfer solution. The encrypted file transfer solutions like FTPS (File Transfer Protocol Secure), SFTP encryption (SSH File Transfer Protocol), and HTTPS (HTTP Secure) help your business from a data breach.
