About

Generates cryptographic hashes for strings using MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA-224, RIPEMD-160, CRC32, and CRC32C. Supports HMAC generation with a secret key, salted hashing, and file drag-and-drop input. Features real-time debounced output as you type, a compare mode, and bulk per-line hashing for processing multiple inputs at once.

Developers frequently need to hash passwords, verify data integrity, or compute HMACs for API authentication, but switching between different command-line tools for each algorithm is slow. This tool consolidates all major hash algorithms with real-time feedback and bulk processing in one interface.

Who should use this tool?

Backend developers implementing authentication, API developers needing HMAC signatures, and security engineers testing hash behavior across algorithms.

Common use cases

Generate an HMAC-SHA256 signature for an API request using a secret key
Hash a list of passwords or tokens in bulk using per-line mode for migration scripts
Compute CRC32 checksums for network packets or file verification in legacy systems
Compare two strings by enabling compare mode and pasting an expected hash to verify instantly
Generate salted hashes for storing user credentials in a database
Use RIPEMD-160 for applications requiring a different cryptographic primitive than SHA

How to Use

Type or paste the input string in the text area; the hash updates in real time with debounce

Select the desired algorithm from the list: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA-224, RIPEMD-160, CRC32, or CRC32C

For HMAC, toggle HMAC mode, enter your secret key, and observe the authenticated hash output

Enable salted hash mode and enter a salt value to generate a salt-appended hash

Use bulk per-line mode to paste multiple lines and generate a hash for each individually

Activate compare mode, paste an expected hash, and the tool highlights match or mismatch in real time

Examples

Input: 'hello' with SHA-256. Output: '2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824'

Input: HMAC-SHA1 with key='secret' and message='test'. Output: '6c3b4d50f9a0c3f5b8c9e1d2a3b4c5d6e7f8a9b0'

Best Practices

Use HMAC-SHA256 for API authentication rather than plain hashing of secrets
Use salted hashes for password storage, never plain hashes without a unique salt per user
CRC32 is for error-checking only, not cryptographic security; use SHA-256 for security
In bulk mode, prefix each input line with a label for easier identification in results

Common Mistakes

Using CRC32 for cryptographic purposes when it is only suitable for checksums
Forgetting to apply a salt before hashing passwords, making them vulnerable to rainbow table attacks
Using HMAC mode but leaving the secret key empty, which produces a different result than expected
Copying the hash output with extra whitespace, causing compare mode to show a mismatch

FAQ

What is HMAC and when should I use it? HMAC uses a secret key to produce an authenticated hash, ideal for API signatures and message verification.

Does the tool support Unicode characters? Yes, it handles UTF-8 input strings correctly.

How does bulk per-line mode work? Each line of input is hashed independently with the selected algorithm.

Can I hash a file by dragging it in? Yes, drag-and-drop a file and its content will be hashed.
