About This Tool
Hash Generator computes SHA-1, SHA-256, SHA-384, or SHA-512 digests for entered text or file bytes. The browser SubtleCrypto digest API produces deterministic one-way hashes. Hashing is neither encryption nor encoding.
What You Can Do
Four Web Crypto algorithms
Hash Generator accepts UTF-8 text or file bytes as its documented input.
Text and file input
The current Hash Generator implementation produces Hex digest.
Hexadecimal digest output
The browser SubtleCrypto digest API produces deterministic one-way hashes. Hashing is neither encryption nor encoding.
How to Use
- 1

Practical Use Cases
Hash Generator workflow
Use Hash Generator when you need to computes SHA-1, SHA-256, SHA-384, or SHA-512 digests for entered text or file bytes.
Result preparation
Create a reviewable Hex digest result while retaining the original UTF-8 text or file bytes.
Privacy and File Processing
Hash Tool keeps its UTF-8 text or file bytes input in browser memory while the operation runs. The workflow creates Hex digest for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs
Input
- UTF-8 text or file bytes
Output
- Hex digest
How It Works
The browser SubtleCrypto digest API produces deterministic one-way hashes. Hashing is neither encryption nor encoding.
Quality and Fidelity
The browser SubtleCrypto digest API produces deterministic one-way hashes. Hashing is neither encryption nor encoding.
Limitations and Important Notes
- SHA-1 is retained for compatibility checks but is not collision-resistant for modern security use.
- Plain hashes are not appropriate password-storage schemes and cannot normally recover the input.
Worked Example
Hash a downloaded file with SHA-256 and compare the hexadecimal digest with a trusted publisher checksum.
Helpful Tips
- Keep a copy of the original UTF-8 text or file bytes while using Hash Generator.
- Validate the Hex digest in its intended destination context.
Frequently Asked Questions
Does Hash Generator execute on the application server?
No. The current Hash Generator operation runs in the browser.
Is the Hash Generator transformation always reversible?
Not necessarily. SHA-1 is retained for compatibility checks but is not collision-resistant for modern security use.
What should I verify after using Hash Generator?
The browser SubtleCrypto digest API produces deterministic one-way hashes. Hashing is neither encryption nor encoding.
