99% of Developers Don't Get Hashing

Comprehensive explanation of cryptographic hashing covering fundamental properties like determinism, pre-image resistance, collision resistance, and the avalanche effect. Explores hash function families from deprecated MD5 and SHA-1 to modern SHA-2 and SHA-3, explains specialized password hashing algorithms like bcrypt, scrypt, and Argon2, and details the Merkle-Damgård construction used to generate hash digests. Emphasizes the distinction between hashing and encryption, the importance of salting passwords, and practical applications in blockchains, Git version control, and data integrity verification.
