Hash Algorithms

MD5

128-bit hash, 32 hex chars. Fast but cryptographically broken. Use only for checksums, not security.

SHA-1

160-bit hash, 40 hex chars. Deprecated for security use but still used in version control (Git).

SHA-256

256-bit hash, 64 hex chars. Part of SHA-2 family. Currently considered secure for most applications.

SHA-512

512-bit hash, 128 hex chars. Higher security than SHA-256 with larger output. Used in blockchain and certificates.

SHA hashes use the Web Crypto API. MD5 is implemented in pure JavaScript. All processing happens locally.
