About the hash text
Runs your text through eight hash functions at once and shows every digest side by side, in hex or Base64. Handy for checking a checksum by eye, reproducing a legacy MD5 comparison, or seeing how the same input maps across SHA families.
Frequently asked questions
Can I reverse a hash back to the original text?
No. Hashing is one-way by design. Short or common inputs can be found by brute force or a lookup table, which is why passwords need a slow, salted function like bcrypt instead.
Which algorithm should I pick?
SHA-256 for general integrity work. MD5 and SHA-1 are broken for anything security-related and belong only in legacy compatibility checks. Never use any of these bare for passwords.
