FAQs
What hash algorithms are supported?
We support 5 popular hash algorithms: MD5 (128-bit), SHA-1 (160-bit), SHA-256 (256-bit), SHA-384 (384-bit), and SHA-512 (512-bit). All hashes are generated simultaneously for easy comparison.
Which hash algorithm should I use?
For security purposes, use SHA-256 or higher (SHA-384, SHA-512). MD5 and SHA-1 are deprecated for security use due to known vulnerabilities, but they're still useful for non-security purposes like checksums and data integrity verification.
Is MD5 secure?
No, MD5 is not cryptographically secure and should not be used for passwords, digital signatures, or security-critical applications. It's vulnerable to collision attacks. Use SHA-256 or higher for security purposes.
What is a hash function?
A hash function takes input data of any size and produces a fixed-size output (hash). The same input always produces the same hash, but it's computationally infeasible to reverse the process or find two different inputs that produce the same hash (for secure algorithms).
Can I hash passwords with this tool?
While you can generate hashes, this tool is for educational and development purposes. For production password hashing, use proper password hashing algorithms like bcrypt, scrypt, or Argon2 with salt and multiple iterations.
Is my data sent to a server?
No! All hashing happens entirely in your browser using the Web Crypto API. Your text never leaves your device, ensuring complete privacy and security.
What's the difference between SHA-256, SHA-384, and SHA-512?
They're part of the SHA-2 family with different output sizes: SHA-256 produces 256-bit (64 character) hashes, SHA-384 produces 384-bit (96 character) hashes, and SHA-512 produces 512-bit (128 character) hashes. Longer hashes provide more security but take slightly more time to compute.
Can I use these hashes for file integrity verification?
Yes! Hash functions are commonly used to verify file integrity. Generate a hash of the original file, then compare it with a hash of the downloaded file. If they match, the file hasn't been corrupted or tampered with.
