MD5 / SHA Hash Generator

MD5 / SHA Hash Generator

Generate hash values from text. Supports common algorithms and optional salting.

MD5SHA-1SHA-256SHA-3SHA-224SHA-384SHA-512

Safe: Processing runs on your device, so input/output is not sent anywhere.

Notes

List of supported hash functions.

MD5	128-bit, 32 hex chars; fast but weak for security
SHA-1	160-bit, 40 hex chars; widely used but considered weak
SHA-256	256-bit, 64 hex chars; strong and commonly used
SHA-3	512-bit, 128 hex chars; strong (different structure from SHA-2)
SHA-224	224-bit, 56 hex chars; weaker than SHA-256
SHA-384	384-bit, 96 hex chars; weaker than SHA-512
SHA-512	512-bit, 128 hex chars; strong
