Data Encryption: Primary Role in File Sharing


Data encryption reformats data into a different form or code protected with a password. At the moment, encryption is one of the best data security methods used worldwide.

There are two main types of encryption: asymmetric and symmetric encryption.


The main reason we use data encryption is to ensure data safety and confidentiality in the digital world.

Modern-day encryption algorithms that guard the security of IT systems are hard to overestimate. They have ousted the out-of-date data encryption standard (DES) and work really well to ensure authentication, integrity, and non-repudiation.

Data encryption algorithms ensure authentication, integrity, and non-repudiation.


Encryption key and encryption algorithm are used to protect data, or plaintext. The outcome of the process is called ciphertext, which can only be accessed in its original form if the correct decryption key is applied. When the same key is used for encrypting and decrypting data it is called a symmetric key. Most data encryption services use symmetric key to encrypt data and asymmetric algorithm to exchange the secret key because they need to securely distribute a large number of keys. Asymmetric cryptography is also called public-key cryptography, it uses one public key and one private key. For public key encryption the Rivest-Sharmir-Adleman (RSA) algorithm is used.


The most widespread way to abuse encryption today is to try random keys to find the matching one. Keep in mind, the encryption power directly depends on the size of the key.

Other ways of attack on encryption are based on breaking the cipher, and are called side-channel attacks and cryptanalysis. They basically try to find a vulnerability in the cipher and abuse it.

Keep in mind that encryption power directly depends on the size of the key. When choosing a file sharing service, pay attention to whether it offers encryption.


The best advice for data protection is to use encryption on devices, email and data. To prevent data theft and malware attacks, companies and individuals should implement email control and auto encryption for sensitive data based on certain keywords contained in the email. Such email encryption software solutions tag, classify, warn, block, and encrypt emails and attachments for safe collaboration within a team or for securely managing outsourced project work. Choose the best data loss prevention software that will handle data encryption on devices, including USB, email and application control. With these precautions taken, you can be sure your data will be safe.

When it comes to sending large files via various file sharing services, pay attention to whether your transfer is encrypted and secure.
