Hash Generator
Encode text to hashes, decode encodings back, and verify integrity
One-Way Hash
MD5, SHA-1, SHA-256, and SHA-512 are one-way functions. You can hash text but cannot reverse it back. Use the Verify tab to check if a hash matches your text. Switch to Base64 or Hex for reversible encoding.
Algorithm Reference
- MD5 (128-bit) — Fast checksum. Not secure for passwords.
- SHA-1 (160-bit) — Legacy. Deprecated for security use.
- SHA-256 (256-bit) — Industry standard. Used in SSL, Bitcoin, TLS.
- SHA-512 (512-bit) — Strongest. For high-security applications.
- Base64 — Encoding (not a hash). Reversible. Used in emails, URLs, APIs.
- Hex — Encoding (not a hash). Reversible. Represents bytes as 0-9, a-f.
