Algorithm Information
MD5 — 128-bit, not cryptographically secure
SHA-1 — 160-bit, deprecated, avoid for security
SHA-256 — 256-bit, recommended for most uses
SHA-512 — 512-bit, highest security
All hashing is performed locally in your browser using the Web Crypto API (SHA) and pure JavaScript (MD5). No data is transmitted to any server.

How to Use This Tool

  1. 1

    Enter your text

    Type or paste the text you want to hash into the input field. The tool supports any text including Unicode characters.

  2. 2

    View all hash outputs

    All five hash algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512) compute simultaneously. Results appear instantly as you type.

  3. 3

    Choose uppercase if needed

    Toggle the uppercase option to display hash values in UPPERCASE. Some systems prefer uppercase hex digits.

  4. 4

    Copy any hash

    Click the Copy button next to any hash to copy it to your clipboard. Use it for file verification, checksums, or password storage.

Frequently Asked Questions

What is a cryptographic hash?
A hash function converts input data into a fixed-size string of characters. The same input always produces the same output, but it's computationally infeasible to reverse the process or find two inputs with the same hash.
Which hash algorithm should I use?
Use SHA-256 for most purposes — it's secure and widely supported. SHA-512 offers higher security. Avoid MD5 and SHA-1 for security-critical applications as they have known vulnerabilities.
Is MD5 still safe to use?
MD5 is cryptographically broken and unsuitable for security purposes. However, it's still useful for non-security checksums, cache keys, or detecting accidental file corruption.
Can I hash files with this tool?
This tool currently supports text input only. For file hashing, you would need a tool that reads file bytes directly. The underlying algorithms are the same.
