Hash Generator (MD5, SHA-256) — frequently asked questions
Is MD5 secure?
No. MD5 and SHA-1 are not safe for security purposes such as passwords; prefer SHA-256 or stronger and a dedicated password-hashing function.
Can a hash be reversed?
Hashes are one-way functions; you cannot directly recover the original text.
Why are my hashes different from another tool?
Check for extra spaces or line breaks and make sure both use the same text encoding (UTF-8).
