How to use Hash Generator
Enter text, choose a secure hash algorithm, and generate a hexadecimal digest with the Web Crypto API. Start with a small known input, run the operation, and compare the result with the format expected by the system you are working with.
What this developer tool does
Generate SHA-256, SHA-384, or SHA-512 hashes from text. It is intended for debugging, prototyping, inspection, and everyday development tasks where a quick local transformation is useful.
When this tool is useful
Use Hash Generator during debugging, prototyping, data inspection, test preparation, or small format conversions. It is designed for quick checks in the browser, while production systems should still rely on tested application code and the relevant technical specification.
How it works
The tool uses the browser Web Crypto API to calculate SHA-256, SHA-384, or SHA-512 digests from the entered text.
Practical example
For example, hash a known test string and compare the digest with a value produced by another trusted implementation.
Developer notes
- A cryptographic hash is one-way; it is not encryption and cannot be “decoded” back to the original text.
- Plain hashes are not a complete password-storage scheme; password systems normally require specialized salted password-hashing functions.
- Use the exact same text encoding and normalization when comparing hashes.
