Cryptographic Algorithms

Cryptographic algorithms are mathematical procedures and protocols used to secure data by enabling encryption, decryption, digital signatures, and authentication. They form the foundation of modern cybersecurity, ensuring confidentiality, integrity, and authenticity in digital communications and storage. Common types include symmetric-key algorithms (e.g., AES), asymmetric-key algorithms (e.g., RSA), and hash functions (e.g., SHA-256).

Also known as: Cryptography, Crypto Algorithms, Encryption Algorithms, Ciphers, Cryptosystems

Why learn Cryptographic Algorithms?

Developers should learn cryptographic algorithms to implement secure systems, such as protecting sensitive data in applications, securing network communications (e.g., HTTPS), and verifying user identities. This is essential for roles in cybersecurity, fintech, healthcare, and any domain handling private information, as it helps prevent data breaches and comply with regulations like GDPR or HIPAA.
