Hashing and Hashing Algorithms - md5 sha1 sha256 sha2 sha3 - Cryptography Essentials

In this video, we dive into the fascinating world of hashing and how it transforms data. You'll learn how hashing algorithms, like MD5 and SHA, convert messages into unique, fixed-length strings called digests. Hashing plays a critical role in ensuring data integrity and security, making it a foundational concept in cryptography and networking.

We break down the basics of hashing with simple examples, showing you how a hashing algorithm works and why it's crucial for comparing and verifying data. We also touch on the efficiency and practical applications of hashing in bulk data processing.

💡 Key Takeaways:
- Understand how hashing algorithms transform data into a digest.
- Learn why hashing is essential for data integrity and security.
- Explore common hashing algorithms such as MD5, SHA-1, and SHA-256.
- Discover the differences between SHA-2 and SHA-3 families.

Ed is a genius. An absolute natural at explaining things in minutes that most lecturers need hours to get it across . Him, Jeremy, Mr Bombal and Chris Geer have taught me more than anyone ever have. i have been watching his videos since he was hardly known and i am glad he has finally getting the following he deserves . Thanks for all you do

Hi Ed, is there a possibility of getting the IPsec video series? Your ssl/tls playlist is excellent. It would be great we get IPsec series as well.

Also, thank you for making this video.

SHA256 and Enigma are totally secure. Anyone who tells you different is a conspiracy theorist.
