A cryptographic hash condenses data of arbitrary length into a fixed-size digest, producing a digital fingerprint. When you add a salt—an extra string placed before or after the data—the digest becomes resistant to precomputed attacks. Common algorithms include MD5, SHA families, SHA-3, and RIPEMD-160, each balancing speed, compatibility, and collision resistance.
This utility lets you drag a file into the browser and view its salted digest instantly. Choose from eleven algorithms, decide where the salt sits, and force uppercase output if required. A single button also generates random hexadecimal salt, protecting you from predictable values while keeping workflows quick. Visual status cues assure you when processing finishes.
IT administrators verify backups, developers validate downloads, and security teams generate integrity checksums before distribution. The on-device approach avoids confidential data leaving your network, aligning with compliance requirements. The copy button streamlines documentation efforts, letting teams paste digests directly into manifests or release notes without mistakes. Automation scripts equally parse the stable output for continuous integration tasks.

Step-by-Step Guide:
Follow these steps to produce a salted digest.
- Drag a file into the highlighted zone or click to browse.
- Wait for the spinner to disappear and the green check icon to show.
- Enter a custom salt or click Generate Random Salt for fresh entropy.
- Select whether the salt appears before or after the file content.
- Pick your preferred hash algorithm from the dropdown Tip.
- Press the copy button to place the digest in your clipboard.
FAQ:
Answers address security and usability concerns.
Is my file uploaded anywhere?
No. Hashing runs inside your browser; the file never leaves your device.
Which algorithm should I select?
SHA-256 offers strong security and wide support, while MD5 suits legacy use cases.
What salt length is recommended?
Sixteen random bytes provide adequate uniqueness for most integrity checks.
Does uppercase affect verification?
No. Hexadecimal digests are case-insensitive; uppercase is purely stylistic.
Can I process very large files?
Browser memory limits may apply, but streaming reads normally handle gigabyte-scale files safely.
Files are processed locally in your browser; nothing is uploaded.
