Definition
Noun: 1. The process or activity of converting plain, readable data or information into a coded form (ciphertext) to prevent unauthorized access. This coded form can only be read or processed after being decrypted with a specific key or password. Encryption is a fundamental technique for securing digital information.
Usage
- Encryption is used as a non-count noun to describe the general concept or process.
- It is commonly used with verbs like , , , , and .
- It often appears in contexts related to computer security, data protection, and communications.
Examples
- Noun:
- Modern messaging apps use end-to-end encryption to protect your conversations.
- The security of online banking depends on strong encryption.
- Breaking the encryption on this file would take years with current technology.
Advanced Usage
- "At-rest encryption": Encryption applied to data that is stored on a device or server (as opposed to data being transmitted).
- The laptop features full disk encryption to protect files even if the device is stolen.
- "In-transit encryption": Encryption applied to data while it is being sent over a network.
- The website uses SSL/TLS for in-transit encryption.
