What is a cryptographic hash?

A cryptographic hash function maps input data to a fixed-length fingerprint. The same input always produces the same hash, but the process is one-way — you cannot recover the original text from the hash.

SHA-256 and SHA-512 are widely used for integrity checks, checksums, and security workflows.

How to Use This Tool

  1. 1

    Enter or paste the text you want to hash.

  2. 2

    Select SHA-1, SHA-256, or SHA-512.

  3. 3

    Click Generate Hash and copy the hexadecimal result.

Common Uses

  • Verify file or message integrity
  • Generate test checksums during development
  • Compare hashed values from APIs or logs
  • Learn how SHA algorithms fingerprint data

अक्सर पूछे जाने वाले प्रश्न

Can I reverse a hash to get the original text?

No. Hash functions are one-way. You can only verify a guess by hashing it again and comparing results.

Is SHA-1 still safe?

SHA-1 is deprecated for security-critical use. Prefer SHA-256 or SHA-512 for new projects.

Is this tool free?

Yes. This tool is completely free to use with no sign-up, no limits, and no hidden fees.

Does my data leave my browser?

No. All processing happens entirely in your browser using client-side JavaScript. Your data is never sent to a server or stored anywhere.
