    Pros and Cons of file encryption

    The Pros:

    • Guarantees data safety
    • Guarantees data integrity
    • Unauthorized parties cannot access your files
    • An added layer of security

    The Cons:

    • Performance overhead
    • Compatibility problems

    What is Encryption, and how does it work?

    Encryption is a security process of transforming data into a context that does not make sense to unauthorized parties. This context can be converted back to make sense to intended parties in a process called decryption. Encryption works by using an encryption algorithm known as a cipher. This generates an encryption key and mathematically transforms readable data (plain text) into gibberish that cannot be read (ciphertext). Depending on the encryption used, anyone with the cipher key can decrypt the ciphertext. Other encryptions use another key for decryption.

    How did we choose the best file encryption tools?

    With many best file encryption tools in the market, it can be a tiresome process trying to decide the best tools to use. But, do not worry; we have compiled a list of best file encryption tools to make the task easy for you. When choosing our list for the best file encryption tools, we considered the following factors:

    • Encryption: This is one of the most critical factors. Encryption determines how secure your files will be. Simple hacking tools can break weaker encryption algorithms. Stronger encryptions, however, guarantee your files will always be safe, as the encryption will require massive resources to break. Even if let us say someone has those resources, which are expensive to come by, it will also take a lot of time. With proper implementation, even supercomputers can take million years to crack the encryption.
    • Performance: The aspect of this factor is the encryption speed. The encryption process is a complex task that needs to be done correctly to ensure the encrypted files are safe. Regarding performance, tools with a higher encryption speed are the best. Also, some tools are slow, but once the process is done, the results are amazing. Speed also depends on the size of your files and algorithm used.
    • Security features: Besides encryption, the best security tools offer other added functionalities such as ability to encrypt folders and even your whole storage. Others offer a password manager – which is essential, the ability to use biometrics, and even a password recovery utility, among others.
    • Pricing: Pricing and type of software play a vital role when getting the best file encryption tool. There are free and premium tools that offer impeccable security. Open source tools are preferred since expert users can look through the source code to ensure there are no flaws. Other proprietary software also provide excellent security and give you the best value for your money.

    What are the various types of encryption available?

    There are two types of encryption that most algorithms and tools use. They are; private key (symmetric) and public-key (asymmetric) encryption. In private key encryption, the same key is used for both encryption and decryption. For public-key encryption, two sets of keys are used. A public key is used for encryption while a private key is used for decryption.

    Do I need to encrypt files on my Mac?

    Sensitive files need to be encrypted to hide the information from prying eyes. This is a safe practice in case your device lands in the wrong hands.

    Should I encrypt backups?

    Similar to any other files, backups can also get to the wrong hands. Moreover, they also contain sensitive information that should only be seen by your eyes. To keep your back up secure, you need to encrypt it every time you update it. This also ensures no one tampers with it.

    Can the encryption be hacked?

    It is a hard task to hack secure encryption such as the AES 128 and the AES 256 bit encryptions. It is estimated that even a supercomputer can take million years to break this kind of encryption. Of course, this depends on several factors, such as how well the encryptions are implemented.

    What if I forget my master password?

    The above tools require a strong master password to operate. These passwords are like a key to a door. If you forget the password, there’s no way you can access your encrypted data. Some other tools offer the ability to recover the master password. In terms of security and privacy, this can make you paranoid. To avoid the hassle that comes with cramming long complex passwords, always use a password manager to manage your passwords.


    Sensitive data is the fuel to cyber-criminal activities. Malicious people can use sensitive data for identity theft, fraud, social engineering, and even blackmail. Besides taking all other necessary precautions, the safest way to guard your sensitive files is by encrypting them. And to do that, you can use any of the best file encryption tools in the above list. Some are entirely free yet reliable, and others are worth the value of your money.
