Understanding Hashing

This course introduces you to the concept of hashing—a fundamental technique in cybersecurity used to protect data integrity and secure information. You’ll learn how hash functions work, their key properties like the avalanche effect and fixed-length output, and where they’re used in real-world applications such as password protection, digital signatures, and blockchain. Perfect for beginners, this course lays a strong foundation for understanding how data can be verified and protected through cryptographic hashes.
