Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text or files. Everything runs in your browser — nothing is sent to a server.

Supported Algorithms

• MD5 — 128-bit hash. Fast but cryptographically broken. Use only for checksums, never for security.
• SHA-1 — 160-bit hash. Deprecated for security purposes since 2017.
• SHA-256 — 256-bit hash. Part of the SHA-2 family. The standard choice for most applications today.
• SHA-512 — 512-bit hash. Stronger than SHA-256, commonly used for password hashing and digital signatures.

Common Use Cases

• Verifying file integrity after downloads (comparing checksums).
• Generating hashes for password storage workflows.
• Creating content-based cache keys or deduplication identifiers.
• Verifying data integrity in API communications.
