Encryption Algorithms
Encryption algorithms are mathematical procedures and protocols used to secure data by converting plaintext into ciphertext, making it unreadable without a decryption key. They are fundamental to cybersecurity, ensuring confidentiality, integrity, and authentication in digital communications and storage. Common types include symmetric-key encryption (e.g., AES) and asymmetric-key encryption (e.g., RSA).
Developers should learn encryption algorithms to implement secure systems, such as protecting sensitive user data (e.g., passwords, financial information) in applications, securing network communications (e.g., HTTPS, VPNs), and complying with data protection regulations like GDPR. Mastery is essential for roles in cybersecurity, backend development, and any domain handling confidential information.
