What is Generador Hash SRI and what is it used for?
Mecanismo de seguridad web (W3C SRI) que garantiza que los archivos cargados desde CDNs de terceros no hayan sido manipulados por atacantes. This tool performs 100% of its processing using modern browser client-side technologies (Web Crypto API, WebAssembly, HTML5 Canvas, and PDF-Lib), ensuring that your sensitive data remains strictly in your device's memory.
When to use this tool?
- ▸ Confidential processing of sensitive documents, contracts, photos, and credentials without uploading to third-party servers.
- ▸ Development workflows, API integration testing, security auditing, and official submissions with strict file constraints.
- ▸ Offline and mobile use without bandwidth delays, zero upload queues, and immediate client-side downloads.
What to verify before using the result
- ✓ Verify that input parameters and character encodings precisely match what the target system or recipient expects.
- ✓ For cryptographic signatures and hashes, remember that signatures authenticate integrity but do not hide contents unless encrypted.
- ✓ Keep your production private keys protected and avoid sharing sensitive tokens in untrusted environments.
