Hash functions convert data of any size into a fixed-size string of characters. They're one-way functions - you can't reverse a hash to get the original data.
Fast but cryptographically broken. Use only for checksums, not security.
Deprecated for security. Still used for git commits and legacy systems.
Secure and widely used. Great for passwords, certificates, blockchain.
Maximum security. Slower but strongest against attacks.
