About Hash Functions

Cryptographic hash functions convert input data into a fixed-size string of characters. They are one-way functions - you cannot reverse a hash to get the original data.

Hash Algorithms

MD5: 128-bit hash (32 hex chars). Fast but cryptographically broken - use only for checksums.
SHA-1: 160-bit hash (40 hex chars). Also deprecated for security purposes.
SHA-256: 256-bit hash (64 hex chars). Part of SHA-2 family, recommended for security.
SHA-512: 512-bit hash (128 hex chars). Stronger variant of SHA-256.

Common Uses

Verifying file integrity (checksums)
Password storage (with salting)
Digital signatures
Data deduplication
