What are Hash Functions?

Hash functions are mathematical algorithms that transform input data of any size into a fixed-size string. The output (hash) is unique for each unique input, making it useful for data integrity verification and security.

MD5

Fast but cryptographically broken. Use only for checksums, not security.

SHA-1

Deprecated for security use. Still used in some legacy systems.

SHA-256

Industry standard. Used in Bitcoin, SSL certificates, and more.

SHA-512

Maximum security. Slower but provides the highest protection.

Common Use Cases

• Password Storage - Store hashes instead of plain text

• File Integrity - Verify downloads haven't been tampered with

• Digital Signatures - Sign and verify document authenticity

• Data Deduplication - Identify duplicate files by hash

• Caching - Generate cache keys from content
