Hash Generator

Generate cryptographic hashes from text or files. Supports SHA-256, SHA-512, SHA-1, SHA-384, and MD5. Compare hashes to verify integrity.

About Hash Generator

A cryptographic hash function takes an input (text or file) and produces a fixed-size output (the hash or digest). Even a tiny change in the input produces a completely different hash — this makes hashes useful for detecting tampering, verifying downloads, and storing passwords.

Algorithms

  • SHA-256 — Part of SHA-2. Produces a 256-bit (64 hex char) hash. The most widely used algorithm today — used in SSL certificates, Bitcoin, and code signing.
  • SHA-512 — Produces a 512-bit (128 hex char) hash. More collision-resistant, faster on 64-bit systems.
  • SHA-384 — A truncated variant of SHA-512. Used in TLS and some certificate standards.
  • SHA-1 — Legacy 160-bit hash. Considered cryptographically broken for security purposes but still used for checksums and Git commit IDs.

FAQ

No — general-purpose hash functions like SHA-256 are not suitable for password storage. Passwords should be hashed with a slow, salted algorithm like bcrypt, scrypt, or Argon2. This tool is for checksums, data integrity, and general hashing.
No. Hash functions are one-way. Given a hash you cannot recover the original input mathematically. The only way to "reverse" a hash is through brute-force or rainbow table attacks, which is why strong passwords matter.
No. All hashing is done using the browser's built-in Web Crypto API (crypto.subtle.digest). Your text or files are never transmitted anywhere.
