What Is Encryption in Computer Security?

In essence, encryption is the process of scrambling information and data into the form which can only be reconstructed by those who hold the keys. This can be done with a wide range of mathematic models and is utilized every day to safeguard the data and information consumers and businesses utilize in their daily lives.

Modern encryption algorithms play a critical role in ensuring the security of digital data stored on computer systems or transmitted via networks like the internet. It also offers security measures like authentication (verifying the origin of a message) as well as integrity (ensuring that it hasn’t been altered) and non-repudiation (the ability to prove that a person or business sent an email).

The encryption process converts plaintext that can be read by humans into an encrypted format known as ciphertext, by utilizing mathematical models, also known as algorithms. The encrypted ciphertext can only be transformed back into plain text using a decryption key which is a secret string of numbers or passwords that the sender and receiver agree on. The more secure the encryption keys, the more difficult it is for third parties to identify using brute force methods.

Many privacy and security laws require a strong encryption in order to ensure that private information remains private and secure. Many people and companies use encryption to protect files or folders as well as entire computers with programs such as 7-Zip and CertainSafe. They can also protect the entire hard drive on the cloud using virtual private networks. Many companies offer multiple encryption solutions to provide the strongest security.
