Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text in your browser. Copy the results without uploading your input text.

How It Works

The tool converts the entered text to UTF-8 bytes whenever the input changes. It calculates MD5 with a JavaScript implementation and calculates SHA-1, SHA-256, SHA-384, and SHA-512 with the browser's Web Crypto API. The input text is processed locally and is not included in Pexlii's tool usage events; those events contain the tool name, category, and action type. This page hashes text only. It does not accept files or compare a result against a supplied checksum. MD5 and SHA-1 are included for legacy compatibility, not as a recommendation for collision-resistant security use.

🔒 Your files and entered content are processed on this device and are not uploaded by this tool. Pexlii also loads Google Analytics for usage measurement; tool events include the tool name, category, and action type, not your files or entered content.

How to Use Hash Generator

1

Type or paste text into the input field.

2

View the MD5, SHA-1, SHA-256, SHA-384, and SHA-512 results as they update.

3

Select Uppercase Output if you want uppercase hexadecimal characters.

4

Click the copy icon beside a result to copy that hash.

Key Capabilities

Real-time hashes for text using MD5, SHA-1, SHA-256, SHA-384, and SHA-512

MD5 uses a local JavaScript implementation; SHA hashes use the browser's Web Crypto API

Toggle hash output between lowercase and uppercase hexadecimal

Copy each generated hash

Application Scenarios

Generating a digest for a text string

Inspecting the outputs of MD5 and SHA-family algorithms for a test string

Copying a text hash into another tool or workflow

Technical Constraints

•This tool accepts text only; it does not calculate file checksums.

•SHA-1 and MD5 are legacy algorithms and should not be used where collision resistance is required.

•SHA-1, SHA-256, SHA-384, and SHA-512 require browser Web Crypto support; MD5 can still be calculated when that API is unavailable.

Frequently Asked Questions about Hash Generator

How do I calculate a SHA-256 hash from text?

Type or paste text into the input field. The SHA-256 result updates in the browser, and you can copy it with the button beside the result.

Is my text uploaded to compute the hash?

Can I use this tool to hash a file?
