Frequently Asked Questions
What are cryptographic hashes?
A cryptographic hash function is an algorithm that takes an input (either text or a file) and returns a fixed-size string of bytes. The output is unique to the input; even a minor adjustment (like changing a single character) will completely transform the hash representation.
Why use SHA-256 over MD5?
MD5 and SHA-1 are considered cryptographically broken and vulnerable to collision attacks (where two different files yield the same hash). SHA-256 and SHA-512 are highly secure, modern standards used for password hashing, blockchain, and critical integrity checks. However, MD5 remains popular for non-security checksums.
