About this course

Securing application data at rest is a critical requirement for modern software development. This text-based course guides you through combining LevelDB, a powerful key-value store, with modern cryptographic principles in Node.js to build secure, efficient local databases.\n\nYou will transition from understanding basic data persistence to designing encrypted storage systems that protect sensitive user information.\n\nWhat you'll learn:\n- Understand the fundamentals of key-value storage and basic cryptographic concepts.\n- Configure and manage LevelDB instances within a Node.js environment.\n- Apply symmetric and asymmetric encryption to secure data before persistence.\n- Implement modern Node.js crypto module patterns, including secure hashing and salting.\n- Query and retrieve encrypted records efficiently using modern async/await patterns.\n- Practice secure key management practices to prevent unauthorized data access.\n\nThe course begins with foundational definitions of cryptography and database storage before moving step-by-step through practical, text-based implementation exercises. It is designed for beginners and JavaScript developers looking to strengthen their security and data storage skills, requiring only basic programming knowledge.
