Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from input text.

Hash generator

MD5, SHA-1, SHA-256, and SHA-512 as you type. All in the browser.

A hash is not encryption. MD5 and SHA-1 are fine for checksums, not for passwords.

What a Hash Function Does

A hash function converts input data into a fixed-length fingerprint. If input changes, hash output changes. This is useful for integrity checks and repeatable identifiers.

MD5 vs SHA

  • MD5: fast, but not secure for cryptographic trust.
  • SHA-1: legacy, also not recommended for security-sensitive usage.
  • SHA-256 / SHA-512: preferred for modern integrity and security workflows.

Practical Use Cases

  • Verify downloaded file integrity.
  • Detect content changes in pipelines.
  • Generate deterministic checksums for caching and deduplication.
