FAQ
Q. Is MD5 secure?
MD5 is no longer considered secure against collision attacks. Use SHA-256 or higher for sensitive data.
Q. Can I reverse a hash?
No, hashes are designed to be irreversible. You can only find the original value through brute-force or pre-calculated rainbow tables.
Use Cases
- Integrity Checking: Verifying that a file or message has not been altered.
- Digital Fingerprinting: Creating a unique identifier for a specific piece of content.
- Secure Storage: Generating hashes of passwords (usually with salt) before database insertion.
Technical Deep Dive
A cryptographic hash function is a mathematical algorithm that maps data of arbitrary size to a fixed-size bit array. It is a 'one-way' function, meaning it's practically impossible to invert.
Limitations
- This tool is for text strings. For very large files, performance depends on the browser's computational speed.
