DiceGen is a free iPhone app developed by Daniel Byon that allows users to easily generate secure and random passphrases using the Diceware algorithm. With this app, even the NSA (probably) won't be able to crack your passphrases.

The Diceware algorithm involves rolling a 6-sided die five times per word in your passphrase. Each set of five rolls is then converted into a 5-digit number, which is looked up in a list of words. This ensures that the passphrases generated are truly random.

One of the key features of DiceGen is the ability to customize the security settings of the generated passphrases. Users can choose the length of the passphrase and adjust the number of words in it. This allows for greater flexibility in creating passphrases that meet individual security requirements.

DiceGen also offers the option to copy the generated passphrase to the clipboard, making it easy to use in various applications. Additionally, all saved passphrases are automatically stored in the passphrase history, providing easy access to previously generated passphrases.

Users can also create passphrases that satisfy website security requirements by capitalizing words or adding a random number or special character. This feature ensures that the generated passphrases meet the specific criteria set by different websites.

It's important to note that while the Diceware algorithm traditionally requires the use of a physical die, DiceGen utilizes a random number generator function instead. While not truly random, this function offers a convenient alternative to rolling a die multiple times.

DiceGen is a free app with no in-app purchases required to access all of its features. It provides a simple and efficient solution for generating secure and random passphrases.
