What is a Hash?
A hash function converts input data into a fixed-size string of characters. Hashes are one-way functions — you cannot reverse them to find the original input. They are widely used for data integrity verification, password storage, and digital signatures.
Supported Algorithms
- MD5 — 128-bit hash (not recommended for security)
- SHA-1 — 160-bit hash (deprecated for security)
- SHA-256 — 256-bit hash (widely used, secure)
- SHA-384 — 384-bit hash
- SHA-512 — 512-bit hash (strongest)
