Frequently Asked Questions

A hash is a fixed-length string produced by a hash function from any input. It is used to verify data integrity, store passwords securely, and create digital signatures.

MD5 produces a 128-bit hash and SHA-1 produces a 160-bit hash; both have known collision vulnerabilities and are not recommended for security use. SHA-256 is part of the SHA-2 family, produces a 256-bit hash, and is considered cryptographically secure.

Hash functions are one-way by design and cannot be reversed mathematically. Common hashes can be cracked through brute force or rainbow table lookups if the input was a weak or commonly used value.
