A cryptographic hash converts your entire text into a short, fixed-length code known as a digest. Any tiny change in the input produces a completely different digest, yet nobody can reconstruct the original text. You rely on hashes to check downloads, secure credentials, and speed up large data lookups everywhere.
This tool generates digests entirely in your browser, letting you choose from modern algorithms, add a random or custom salt, and switch casing without refreshing the page. A responsive summary panel shows the result, algorithm badge, and salt position immediately. Press Copy to move the digest to your clipboard for scripts or databases.
Use it when you need a quick checksum for a firmware image, want to track document versions, or plan to store credentials as salted digests in a development database; always confirm algorithm length and casing expectations with your target system, particularly if older libraries reject lowercase output, before deploying the result.
Technical Details:
The interface runs exclusively inside your device using a reactive scripting layer that binds each form control to a browser cryptography engine. Updating any field instantly recalculates the digest without sending network requests. Parameters mirror in the URL query string so you can bookmark or share reproducible configurations safely.
Multi-Algorithm Support
Select from classic and modern hash functions, including five SHA variants, to match external systems, audit legacy data, and future-proof your workflows.
Custom Salt Input
Enter any alphanumeric salt, then place it before or after the text to reinforce digest uniqueness against rainbow-table attacks and credential reuse risks.
Random Salt Generator
Generate a cryptographically strong 16-byte salt instantly, removing manual typing and guaranteeing high entropy for each password or token you process.
Uppercase Toggle
Switch the digest to uppercase for systems that reject lowercase, ensuring seamless import into mainframe utilities or legacy APIs without secondary conversion steps.
One-Click Copy
Copy the digest straight to your clipboard, receiving instant visual feedback, so you avoid selection errors and speed up repetitive verification tasks.
Shareable URL
Every setting appears in the address bar, allowing you to bookmark a specific configuration or send colleagues an exact replica for consistent testing.
Step-by-Step Guide:
Follow these steps to produce and export a digest:
- Paste or type your content into the Text area.
- Select a desired algorithm from the Hash type dropdown.
- Optional Click Advanced, enter a value in Salt, then choose Prefix or Suffix.
- Optional Toggle Output casing to convert the digest to uppercase.
- Press Copy to place the digest on your clipboard and share or store it wherever required.
FAQ:
Find quick answers to common questions.
Is my data stored?
No. All processing happens locally in your browser, and nothing is transmitted to any server.
Which algorithm should I pick?
Choose the hash function required by your target system. SHA-256 suits modern applications; legacy platforms may expect MD5 or SHA-1.
Why add a salt?
Salting adds uniqueness, stopping attackers from using pre-computed tables to reverse common passwords.
How do I verify a file?
Generate the digest for the file’s contents elsewhere, then compare it byte-for-byte with the digest produced here.
Why is my digest longer?
Different algorithms output different lengths. For example, SHA-512 produces 128 hex characters, while MD5 outputs 32.
Troubleshooting:
If something does not work as expected, check these pointers.
- Digest stays blank: Ensure the Text area contains at least one character.
- Clipboard remains empty: Your browser may block programmatic copy; allow clipboard access or use manual selection.
- Salt position does not update: Expand the Advanced panel and re-select Prefix or Suffix.
- Uppercase setting ignored: Clear browser cache and reload to refresh the scripting layer.
- URL becomes lengthy: Shorten the input text or omit the salt before sharing the link.
Advanced Tips:
Get more from the generator with these suggestions.
- Drag files into the text area to hash their contents via your system’s clipboard.
- Bookmark preset URLs for repetitive tasks like nightly backup verification.
- Compare two digests quickly by pasting them side by side in a plain-text diff tool.
- Chain salting by applying a second salt to an already hashed value for layered security.
- Automate clipboard capture with command-line utilities to integrate the generator into build scripts.
