SHA256 / MD5 Hash Generator
Use this tool to generate cryptographic hashes (SHA-256 or MD5) for any input string. It's useful for password hashing, data integrity verification, and secure encoding.
What is a Hash Generator Tool?
A hash generator is a cryptographic tool that converts plain text into a fixed-length string of characters. Hashing is a one-way operation — meaning once data is hashed, it cannot be reversed to retrieve the original input. Developers use hashing algorithms like SHA-256 and MD5 to ensure data integrity, verify passwords, and detect tampering in files or APIs.
SHA-256 vs MD5 — What’s the Difference?
| Feature | SHA-256 | MD5 |
|---|---|---|
| Hash Length | 64 characters | 32 characters |
| Algorithm Type | SHA-2 Family | MD (Message Digest) |
| Security | Highly secure, collision-resistant | Weak, vulnerable to collisions |
| Use Cases | Password hashing, blockchain, digital signatures | File checksums, legacy systems, quick integrity checks |
Why Use a SHA-256 or MD5 Hash Generator?
- Verify file integrity after download or upload
- Store passwords securely using one-way hashing
- Ensure consistency across APIs and data transfers
- Detect changes in content or configuration files
How Does This Online Hash Generator Work?
Simply enter any text, select your preferred algorithm (SHA-256 or MD5), and click Generate Hash. The tool runs entirely in your browser, meaning your data never leaves your device — ensuring complete privacy and security. You can easily copy the hash result to use in your applications or documentation.
Frequently Asked Questions
1. Can I reverse a SHA-256 or MD5 hash back to text?
No, hashing is a one-way function. It’s designed to be irreversible, meaning you cannot retrieve the original text from the hash value.
2. Which algorithm should I use — SHA-256 or MD5?
For modern security and password storage, always use SHA-256. MD5 is faster but outdated and vulnerable to collisions.
3. Is this hash generator secure?
Yes. This tool performs hashing client-side using Web Crypto API and CryptoJS. No data is sent to any server, ensuring your input remains private.
