What is Hash Generator?
The Hash Generator computes cryptographic hash values from text or files. It supports MD5, SHA-1, SHA-256, and SHA-512 algorithms. You enter text or upload a file and the tool produces the hash in hexadecimal format. Hashes are used to verify data integrity, create checksums, and in security applications. All processing happens in the browser.
How does Hash Generator work?
This tool uses the browser's SubtleCrypto API to compute SHA hashes and a JavaScript library for MD5. It takes input as a string or file, processes it through the selected algorithm, and outputs the hash as a hex string.

Common Use Cases
Verifying file integrity
Generate a hash of a downloaded file and compare it with the published checksum.
Creating checksums for uploads
Generate a SHA-256 hash of a file before uploading so the receiver can verify it.
Comparing file contents
Hash two files and compare the results to check if they are identical.
Development and testing
Generate hashes for test data or configuration values.
How to Use This Tool
Enter text or upload a file
Type text in the input area or drag and drop a file.
Select algorithm
Choose MD5, SHA-1, SHA-256, or SHA-512.
Generate
Click Generate to compute the hash.
Copy the hash
Copy the hex string for use in verification or code.
Pro Tips
- 1
SHA-256 is the recommended algorithm for security applications.
- 2
MD5 is fast but not collision-resistant. Use it for checksums, not security.
- 3
The same input always produces the same hash (deterministic).
- 4
Even a one-character change produces a completely different hash (avalanche effect).
Frequently Asked Questions
What algorithms are supported?
MD5, SHA-1, SHA-256, and SHA-512. SHA-256 is the recommended choice for modern applications.
Can I hash files?
Yes. Upload a file or drag and drop it onto the tool to generate its hash.
Is my data sent to a server?
No. All hashing happens in your browser. Nothing is transmitted.
What is a hash used for?
Hashes verify data integrity, create checksums, store passwords (with salting), and identify duplicate files.
Is MD5 still safe?
MD5 is broken for security purposes due to collision vulnerabilities. Use SHA-256 or SHA-512 for anything security-related.
