Tips for better results
- Hashing is one-way but plain passwords still need dedicated password hashing.
- The same input always creates the same SHA-256 digest.
- Even tiny input changes produce a very different digest.
Privacy and browser compatibility
The supported operation runs locally in a modern browser, so the text or values you enter do not need to be sent to Kaazo for server-side processing. Very large inputs can still be limited by the memory and performance of your device.
For business, financial, legal or production-development work, review the result before using it as a final source of truth. A browser utility is designed to speed up common tasks, not replace specialist professional software or advice where that is required.
