With the help of the default CharacterData implementations, we can formulate the rules required for the password. It however does not guarantee that the password always contains both digits and letters, but most of the aforementioned suggestions also doesn't do that. I saw an interesting solution to the "random" problem when I signed up for my RIM signature codes. In this tutorial, we'll look at various methods we can use to generate a secure random password in Java. Would like to know if the code below is a secure way to generate passwords and if it can be improved. The following code examples are extracted from open source projects. That is bit suspect. RandomStringUtils speaks for itself. toUpperCase (); 20 = number of random chars in the generated password, you can change this number based on how many chars you want in your random generated password.

You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Supports passwrod limit, must have characters and how much of them, char ranges and a list of them. Also you should use much larger parameter to second RND.nextInt() call, something like MAX_INT, otherwise distribution of passwords may be skewed. So our encrypting passwords and then checking for passwords are using the exact same code in Spring Security and for some users the first password is randomly generated, then sent to the encrypt code and saved to our users table. On a side note, Apache advocates the usage of RandomStringUtils … RandomStringUtils a deux problèmes: #1 ne garantit pas les exigences de caractère d'au moins une majuscule, une minuscule, un chiffre et un caractère spécial.
