Encryption

Encryption is a fundamental security technique that transforms readable data (plaintext) into an unreadable format (ciphertext) using algorithms and keys, ensuring confidentiality and integrity during storage or transmission. It is widely applied in areas like secure communications, data protection, and authentication systems to prevent unauthorized access and tampering.

Also known as: Cryptography, Data Encryption, Ciphering, Encryption Algorithms, Encrypt

Why learn Encryption?

Developers should learn encryption to implement security in applications, such as protecting sensitive user data (e.g., passwords, financial information) in databases or securing network communications (e.g., HTTPS, VPNs). It is essential for compliance with regulations like GDPR or HIPAA, and for building trust in systems that handle private or critical information.
