Security & Encoding

Use this group for a password, an identifier, a hash, or a shuffled list. The work stays in the browser.

The password generator builds a random string on your device. 1CLIK does not see it and does not store it. Copy it into your own password manager. A UUID is an identifier, not a password. The hash tools compute SHA digests. They do not reverse a hash and they do not recover a password. If a page somewhere claims to decrypt SHA-256, that claim is false.

Shuffle a list when you need a new order for names or lines you paste. The draw is not a legal raffle. The barcode tool draws a Code 39 label from letters and digits. Scan the image before you print it on a package. It is not a QR code and it does not look up a product.

Hiding part of a photo or a PDF is a different job. Use the redact tools in Image and Photo or PDF.
