❓FAQ

Q: What is a hash function?

A: A hash function is a mathematical algorithm that converts input data of any size into a fixed-size string of characters. The output (hash) uniquely represents the input data and is used for data integrity verification.

Q: What's the difference between hash algorithms?

A: MD5 produces 128-bit hashes (32 characters), SHA-1 produces 160-bit hashes (40 characters), SHA-256 produces 256-bit hashes (64 characters), and SHA-512 produces 512-bit hashes (128 characters). Longer hashes are more secure but take slightly more time to compute.

Q: Is MD5 still secure?

A: MD5 is no longer considered secure for cryptographic purposes due to known vulnerabilities. For security-critical applications, use SHA-256 or SHA-512 instead. MD5 is still useful for checksums and non-security purposes.

Q: What are hashes used for?

A: Hashes are used for password storage, data integrity verification, digital signatures, file checksums, blockchain, and detecting duplicate data. They ensure data hasn't been tampered with.
