Generators create a file or string on demand. Scan QR codes before printing, store passwords in your own manager, and remember that hashing is not encryption.
QR code generator encodes text or a URL into a downloadable PNG. Long inputs make denser codes—test at the intended print size. Password generator builds random strings with your chosen length and character sets; we do not save them for recovery.
Hash generator computes digests for text comparison and learning. MD5 is unsuitable for security-sensitive integrity decisions. For file verification, use a tool that hashes file bytes rather than pasted text.
