Hash Generator.
Generate SHA-256, SHA-1, and MD5 cryptographic hashes from any text. All processing is browser-native — your input never leaves your device.
Cryptographic Hash Functions Explained
A cryptographic hash function takes an input of any length and produces a fixed-length output (the hash or digest). The same input always produces the same output. Different inputs should produce different outputs — a property called collision resistance. Hash functions are one-way: given a hash, it is computationally infeasible to recover the original input.
SHA-256
SHA-256 (Secure Hash Algorithm 256-bit) is part of the SHA-2 family, designed by the NSA and published by NIST in 2001. It produces a 256-bit (64 hexadecimal character) digest. SHA-256 is the current industry standard for security-sensitive applications: Bitcoin uses it for proof-of-work and address generation, TLS certificates use it for integrity verification, and most modern authentication systems use it for password hashing (typically combined with salt via PBKDF2, bcrypt, or Argon2).
SHA-1
SHA-1 produces a 160-bit (40 hexadecimal character) digest. It was the dominant hash function from 1995 through the early 2010s but has been cryptographically broken — a practical collision attack was demonstrated by Google in 2017 (the SHAttered attack). SHA-1 should not be used for new security-sensitive applications. It remains in use for legacy systems, Git commit identification, and checksum verification where collision attacks are not a practical threat.
MD5
MD5 produces a 128-bit (32 hexadecimal character) digest. It is the fastest of the three but also the weakest. MD5 collisions can be generated in seconds on modern hardware. MD5 should never be used for passwords or any security purpose. Its remaining legitimate uses are non-cryptographic checksums (verifying a file download was not corrupted) and legacy database fingerprinting.
Common Use Cases by Algorithm
- SHA-256: Password hashing (with salt), digital signatures, blockchain, API request signing, certificate integrity
- SHA-1: Git commit IDs, legacy SSL certificates (being phased out), file deduplication in non-security contexts
- MD5: File integrity checks (not for security), ETags in HTTP caching, legacy database deduplication
