FAQ
?Is this online hash generator secure for passwords?
Yes, because the hashing logic runs entirely within your browser on your device, your raw text (like passwords) is never transmitted over the internet.
?Does this tool support MD5?
We focus on modern, secure hash algorithms (the SHA family). MD5 is considered cryptographically broken and is excluded to encourage better security practices.
