About Hash Generator

The Hash Generator is a powerful, secure, and free online tool designed for developers, security professionals, and anyone needing to verify data integrity. It allows you to transform any text input into a fixed-size string of characters, known as a 'hash' or 'digest'. Supported algorithms include the widely used MD5 (128-bit), SHA-1 (160-bit), and the stronger SHA-2 families: SHA-256, SHA-384, and SHA-512. Unlike other online tools that send your data to a server, this tool runs entirely in your web browser using modern web cryptography APIs. This ensures that your sensitive data (like passwords or private keys) remains private and is never exposed to the network.

How to Use Hash Generator

  • 1
    Input Text

    Type or paste the text content you want to hash into the input field.

  • 2
    Select Algorithm

    Choose your desired hashing algorithm (e.g., SHA-256) from the dropdown menu.

  • 3
    Customize Output

    Use the 'Uppercase Output' toggle if you strictly need the hash in uppercase format.

  • 4
    View & Copy

    The hash is generated instantly. Click the copy icon to save it to your clipboard.

Frequently Asked Questions

No, cryptographic hashing is a one-way process. It is mathematically impossible to reverse a hash to retrieve the original input.
No, MD5 is considered broken and insecure for passwords due to collision vulnerabilities. Use SHA-256 or stronger algorithms for security.
No, your text is hashed locally using the Web Crypto API ensuring your private data remains in your browser.
SHA-256 produces a longer (256-bit) and much more secure hash than SHA-1 (160-bit), which is now considered vulnerable to collision attacks.
That is a fundamental property of cryptographic hashes; regardless of the input size, the output hash is always a fixed length string.
Yes, the tool treats newlines as part of the input, producing a unique hash for the entire multi-line text block.
