Hash functions transform text of any length into a fixed-size, seemingly random string called a digest. Salting appends or prepends an extra value so identical inputs hash differently, countering rainbow-table attacks. Algorithms like MD5, SHA-1, SHA-2, SHA-3, and RIPEMD-160 vary in speed and collision resistance, supporting different security requirements. The digest length remains constant regardless of source length.
The generator below lets you paste text, choose an algorithm, and apply a custom or random hexadecimal salt. Toggle placement to prefix or suffix, force uppercase output, and copy the digest in a single action. Real-time computation updates as you type, enabling iterative testing or quick verification. Visual feedback confirms clipboard actions.
Developers embed the hashes into configuration files, password stores, and message authentication codes. Teachers illustrate cryptographic principles during lessons, while quality-assurance teams reproduce test fixtures reliably. Because every calculation occurs locally, sensitive input never leaves your machine, aligning with strict privacy policies. Command-line aliases can also invoke the page with query parameters for automated pipelines.

Step-by-Step Guide:
Follow these steps to generate a secure digest.
- Paste or type the text into the input area.
- Enter a custom salt or click Generate Random Salt.
- Set the salt position to prefix or suffix as required.
- Choose a hashing algorithm from the list Tip.
- Tick Uppercase output if your system demands capital letters.
- Press the copy button to place the digest on the clipboard.
FAQ:
Answers address security, functionality, and automation.
Is any data sent to a server?
No. The entire hashing operation happens locally; nothing leaves your device.
Which algorithm is best for security?
SHA-256 or SHA-3 variants offer strong resistance to current attack techniques.
Why would I use a salt?
A salt prevents attackers from using precomputed tables to reverse hashes.
Does uppercase change the hash value?
No. Hexadecimal is case-insensitive; uppercase aids readability only.
Can I automate input via URL parameters?
Yes. Append query strings for the text, salt, and algorithm to preload the page.
No data is transmitted or stored server-side.
