If unauthorized parties have ever accessed or stolen your sensitive files, you’ve likely searched for ways to tighten security. If you’ve never been a victim of breached privacy, however, you still need the best encryption software to keep things that way.
Regardless of your reason, your quest for a competent encryption program requires a bit of learning. Knowing how encryption software works, what various programs offer, and how these details apply to the type of files you want to protect are prerequisites for spotting the right application.
This article will cover those areas but focus on the best security programs for various needs to help you identify the right option.
What Is Encryption Software?
Data encryption software is any tool or application designed to make information unreadable using cryptographic algorithms. Scrambled data, in such cases, can only be readable when specific decryption keys are provided.
Each encryption tool protects your data using different methods and features. We’ll review the types of encryption and the features you should expect.
How Does Encryption Work?
Whenever you think about encryption, imagine a process that turns data into meaningless digital material. Only parties with the correct decryption keys can piece the data together to make it decipherable.
The process involves the data, an encryption engine, and a key manager. The engine uses cryptographic mathematical formulas called algorithms to convert protected information from its readable state (plaintext) into unreadable data (ciphertext). The key manager supplies the cryptographic keys (cipher) required to read the scrambled data.
Encryption can be deployed when data is stationary (at rest) or in transit (in motion). At-rest or stationary data indicates files and information stored in one place, such as disk drives on computers, network drives, cloud servers, or databases.
Encryption in transit secures data, such as emails, flowing between two or more devices.
Types of Encryption
Types of encryption refer to how encryption keys are applied to protect data. There are two major types:
Symmetric encryption
Symmetric encryption involves encrypting and decrypting data using the same key. Most algorithms, such as AES and Blowfish, use this type of encryption. It is mainly deployed for personal at-rest data, but files encrypted with this technology can also be shared.
However, users must be careful to transmit the keys securely.
- Faster for encrypting large amounts of data
- Uses less memory, processing power, and time to encrypt data, unlike asymmetric encryption
- The use of one key for encryption and decryption introduces a significant weakness, as one must securely transmit decryption keys separately when sharing encrypted files
- Future communications will become vulnerable if the same encryption key is used and its keys are compromised
- Managing multiple users can become complex
Asymmetric encryption
This type of encryption is also called Public Key Infrastructure (PKI) and public-key cryptography. It employs private and public keys to eliminate the weakness of using one key for encryption and decryption.
With PKI, you can use a person’s public key to encrypt data, which can only be decrypted by the individual using their private key. On the flip side, you can encrypt data using your private key to allow others to decrypt it with your public key if you want to prove you own a file.
- Using two separate keys makes for better security
- It’s more scalable than symmetric encryption since one public key can be shared with multiple users
- Using a private key means the recipient can validate the origin of the file or message
- Requires more computational power than symmetric encryption
- More complex and involves a learning curve for non-technical users
Methods of Encryption
Methods of encryption indicate how symmetric or asymmetric encryption is applied to data. They include the following:
File encryption | Secures at-rest files and folders that reside within storage devices and platforms |
Disk encryption | Encrypts the entire drive and requires passwords or keys to gain access. |
End-to-end encryption (E2EE) | Data is encrypted on the sender’s device and decrypted on the recipient’s device. It combines symmetric and asymmetric encryption because the recipient’s public key is used to encrypt the data before transmission. |
Email encryption | Ensures that emails are only readable by intended recipients. Employs the same principle as E2EE. |
Database encryption | Used to secure data stored on databases. It could be customer or student information. |
Network encryption | Involves encrypting data moving between devices on a network (including the Internet) to avoid interception by malicious third parties. Uses protocols like Transport Layer Security (TLS) |
How Does Data Encryption Software Work?
Encryption software allows users to input the data they intend to protect, deploys the encryption algorithm to scramble the data, and generates the encryption key required to read the data.
Not all data encryption software applications offer the same type of encryption, as some work better than others in specific use cases. For example, cloud or email encryption tools may not be needed to encrypt data stored on local computers. However, some tools are sold as all-in-one packages that offer a bit of everything.
Many programs also provide more advanced features to help users improve security and conveniently encrypt and decrypt data.
These could include password and key management, file-sharing, and end-to-end encryption.

- You want missing features like two-factor authentication, encrypted storage creation, and self-decrypting EXEs.
⇢ Why I picked it
AxCrypt is one of the many encryption software programs on this list that uses the US government-approved AES algorithm.
Encrypting an app is as easy as dragging and dropping a file to the main window. It automatically overwrites the encrypted file on your drive instead of leaving the unencrypted original copy for you to delete. This feature is called secure deletion.
Another nifty capability that AxCrypt possesses is on-the-fly encryption, which is something you should look for in other apps. You can open encrypted files in their native programs and modify them without having to decrypt, edit, and encrypt again.
However, that feature means people with physical access to your logged-in device can use your encrypted files. Just don’t forget to press Windows + L when leaving your computer. You should also use shorter wake or time-out periods.
You need an account to use the program, which involves providing (and verifying) an email address. You will also be prompted to create a master password, which serves as the key to everything. Losing the master password means you’ve lost access to your account and encrypted files. So, keep it safe.
Xecrets Ez: Cheaper AxCrypt alternative

⇢ Why I picked it
You can encrypt files that you send via email if you encrypt them locally before transmitting. However, the contents of your mail will remain unencrypted at rest even though most clients use encryption-in-motion. Proton Mail is the best option for full email encryption, as the client is built on OpenGPG’s end-to-end encryption standard.
Emails you send to other Proton Mail users are encrypted by default. However, sending an encrypted email to someone outside the Proton Mail ecosystem is different. The recipient gets a link that takes them back to the Proton environment, where they must provide a password to access the message.
![Emails you send to other Proton Mail users are encrypted by default](https://www.auslogics.com/en/articles/wp-content/uploads/2025/02/Encrypted-Proton-Mail-content.png)
To send such a message, click the padlock icon at the bottom of the message window and set a password and hint. The hint will be displayed to the recipient.
Messages also expire at a specific date which is displayed in the message.
The only setup required is to create a new account with Proton. If you don’t want to miss your old emails, the platform allows you to transfer emails from your old clients. You can also choose a subscription package while you’re at it if you want advanced features.

⇢ Why you should avoid it
- You only want to use a local account with Windows and don’t trust yourself to safely back up your encryption keys.
⇢ Why I picked it
BitLocker may not be a standalone app that allows you to encrypt individual files and folders, but it is an important and effective utility for whole-drive security. Its job is to encrypt your entire hard drive, so no one except you will have access.
You will be required to provide your encryption key, PIN, or password to access the drive, depending on your preference. The feature can save your BitLocker recovery keys to your computer’s TPM for hardware-level security if you lock your internal drive.
Here are the steps you can follow to use BitLocker:
- Right-click the drive and select Turn on BitLocker.
- If you want to encrypt a removable drive or another internal hard drive, you will be required to provide an unlock password or use a smart card for decryption. Select an option and click Next.
- If you’re encrypting the hard drive where Windows is installed, you should see the backup wizard straightaway.
- You can print the key, save it to a file, or save it to your Microsoft account (if you’re logged in).
- Click the Next button.
- The next page will ask whether you want to encrypt the entire drive or used disk space. Encrypting the entire drive can be quite slow, but it’s the best option if you’re already using the drive.
- Choose encryption mode. The new mode is recommended if you don’t intend to use the drive on Windows versions older than Windows 10 version 1511.
- Click the Next button.
There are really no reasons to avoid BitLocker. You can keep it turned on or use it for removable drives while using other encryption programs for file, folder, and cloud encryption.

⇢ Why I picked it
FileVault is the Apple version of BitLocker. It is used to encrypt macOS drives to prevent unauthorized access.
While macOS devices with T2 security chips and Apple silicon are encrypted by default, users can turn on FileVault for extra security. Once turned on, the device will ask for a user’s password before the boot process begins.
You can also use FileVault to encrypt your removable storage devices.
Here’s how to turn on the feature for your internal drive:
- Click the Apple menu.
- Select System Settings.
- Go to the sidebar and click Privacy & Security.
- Locate and select FileVault.
- Click Turn On and enter your password if prompted.
- Next, choose whether you want to provide a recovery or use your iCloud account to recover your password if you forget it.
- Click the Continue button.
To encrypt a removable drive, first ensure it is formatted with the Apple File System (APFS) or macOS extended file system. If not, go to disk utility and format your drive to encrypt it. This process will erase your data.
If the drive has the right file system, go to the Finder window, right-click the drive, and select Encrypt. Provide a password and hint. Click Encrypt Disk. You’ll be prompted to provide that password whenever you come to the USB drive.

⇢ Why should avoid it
- You want to use different encryption standards.
- You want more encryption features like text encryption, encrypted storage creation, and PKI.
⇢ Why I picked it
7-Zip is one of the most powerful and competent compression and archival software programs around. Many might not see it as an encryption application, but you’ll be surprised how well it can keep your files private.
The setup process is easy. Download the tool’s installation package and run it. You can choose to use it as a portable package if you like.
You don’t have to create an account or login credentials to use 7-Zip. Just compress your files or folders and lock them with passwords. Whoever wants to open your files must supply their passwords.
The process becomes tricky when you realize people can still see the file names within the protected ZIP files. They just can’t access the file.
If you don’t want unauthorized parties to see file names, compress the files you intend to protect into a ZIP file. After that, compress that ZIP file again and protect it with a password.
But that’s where 7-Zip’s security options start and stop. You have to look elsewhere if you need features like self-decrypting EXEs, two-factor authentication, password management, and public key cryptography.

- On-the-fly encryption
- Whole disk encryption
- Hidden containers
- Lacks cloud storage
- Does not securely delete unencrypted original files
⇢ Why you should use it
- It provides all the basic encryption features you need for free.
- You want to encrypt internal and removable drives.
- You need a program that works across different platforms.
⇢ Why you should look elsewhere
- You need to create self-decrypting executables.
- You need a program that securely deletes unencrypted originals.
- You want cloud encryption.
⇢ Why I picked it
VeraCrypt is one of the most popular and robust free encryption programs around. It is based on the now-abandoned TrueCrypt program but comes with numerous improvements and fixes. The app is feature-rich and provides various types of encryption algorithms. It even allows you to use a combination of about 15 algorithms to improve security.
Like many other encryption tools, VeraCrypt uses file containers, usually called vaults or virtual disks, to encrypt files and folders. You will move the files and folders you want to encrypt to the virtual disk (which is a regular file).
Whenever you want to view or access the file, you must mount the virtual disk in the VeraCrypt app and use your files like you’re working from another hard drive within your computer.
You can also encrypt whole disk drives or partitions, including the volume or drive that houses your operating system.
The entire process starts with clicking the Create Volume button when you open VeraCrypt.
You can install VeraCrypt just like you would any other program. However, the developers also provide a portable version that does not require encryption. You can access different packages on the download webpage.
VeraCrypt’s hidden volume feature
VeraCrypt allows you to create a hidden volume within a container. It involves setting up an outer volume that works as a false container and another hidden one you don’t want to divulge. The hidden volume only shows up if you input the password allocated to it after mounting the file you created.
That way, even if you’re held at gunpoint and forced to decrypt your files, you can provide the password to the outer volume.
Key Features to Look For in Encryption Software
The algorithm an encryption software uses determines how well it can withstand attacks. Most programs employ AES, which is formidable enough to protect your data. Programs that support public-key cryptography combine other standards, such as Elliptic-curve cryptography (ECDH, ECDSA, and EdDSA) and RSA.
If you want to use different algorithms, go for options like Advanced Encryption Package and VeraCrypt that let you choose encryption standards.
Use a program that supports all the operating systems and devices you intend to use.
Some programs have better interfaces than others. Options like GnuPG are reserved for advanced users, while AEP’s GUI may be too dated. VeraCrypt, AxCrypt, and Cryptomator are examples of user-friendly applications.
Automatic secure deletion means you don’t have to worry about the program leaving the unencrypted original file behind. If you must go for an app without the feature (like VeraCrypt), you should download another free tool that can help you delete files securely.
Having multiple login fronts is a nice-to-have feature. That’s because hackers can access your encrypted data if they get a hold of your password, and you don’t have an extra layer of protection.
Some encryption programs are not cheap. While many offer lifetime licenses, some, like AxCrypt, require monthly and annual subscriptions. If free encryption software packages do not offer the features you need, check the paid products that fit into your budget.
Try the Best Encryption Software That Works for You
Before picking data encryption software, assess your requirements and your budget to confirm whether the app meets your needs. For example, there’s no point going for a free option that does not support macOS if you frequently move files between a PC and a Macbook. You should also consider discount offers for paid products if you can’t afford their regular prices since some of these programs offer more robust options than free alternatives.
