Frequently Asked Questions


What is a hash function?

A hash function is a mathematical algorithm that takes an input (or 'message') and returns a fixed-size string of characters, which is typically a hexadecimal number. The output is unique to each unique input.

What's the difference between MD5, SHA-1, SHA-256 and SHA-512?

MD5 produces a 128-bit hash (32 characters).
SHA-1 produces a 160-bit hash (40 characters).
SHA-256 produces a 256-bit hash (64 characters).
SHA-512 produces a 512-bit hash (128 characters).

SHA algorithms are generally more secure than MD5, with SHA-512 being the most secure among these options.

Is this tool secure?

Yes! All hashing is performed locally in your browser. Your input is never sent to any server, ensuring complete privacy and security.

What can I use hash values for?

Hash values are commonly used for data integrity checks, password storage (with proper salting), digital signatures, and in blockchain technology.

Can I reverse a hash to get the original text?

No, hash functions are designed to be one-way functions. While there are rainbow tables and brute-force attacks for simple inputs, properly hashed data cannot be reversed to its original form.
