Encryption

The process of converting data into a secure format to prevent unauthorized access.

Understanding Encryption

Encryption plays a critical role in digital security, safeguarding sensitive information from unauthorized access, tampering, and cyber threats. It ensures:

Confidentiality – Data remains inaccessible to unauthorized users.
Integrity – Ensures that data is not altered in transit or storage.
Authentication – Verifies the legitimacy of the sender and recipient.

Key Features of Encryption

Mathematical Complexity – Uses cryptographic algorithms for secure data transformation.
Key Management – Securely handles encryption and decryption keys.
Data Protection Across Channels – Secures data at rest, in transit, and during processing.

Common Applications of Encryption

Secure Communication – TLS/SSL, VPNs, end-to-end encrypted messaging.
Data Protection – Full disk encryption, database encryption, cloud security.
Digital Authentication – Digital signatures, blockchain transactions.
