FAQ
What is MD5?
MD5 (Message-Digest Algorithm 5) is a widely used hash function that produces a 128-bit (16-byte) hash value, typically represented as a 32-character hexadecimal string.
What's the difference between 16-bit and 32-bit?
32-bit is the complete MD5 hash (hexadecimal representation of 128-bit binary). 16-bit takes the middle 16 characters from the 32-bit hash, commonly used in legacy password systems but less secure.
Is MD5 secure?
MD5 has collision vulnerabilities and is not recommended for security-sensitive scenarios (like password storage). However, for file integrity verification, MD5 is still a fast and effective choice.
Is my data uploaded to server?
No. All calculations are performed locally in your browser, data never leaves your device.
