❓ Frequently Asked Questions
How does hash identification work?+
Hash types are identified by their length, character set, and format. For example, MD5 is always 32 hex characters, SHA-256 is 64 hex characters, and bcrypt starts with '$2b$'.
Can a hash be reversed to get the original data?+
Cryptographic hashes are one-way functions — they cannot be reversed. However, weak passwords can be found using rainbow tables or brute force against the hash.
Which hash algorithms are secure?+
SHA-256 and SHA-3 are secure for general use. For passwords, use bcrypt, scrypt, or Argon2 (which are slow by design). MD5 and SHA-1 are considered broken and should not be used for security.
