Imagine getting feedback like 'Sorry, your password is 0.1 units not complexified enough.' The inputfield currently says 'too common' when failing the complexify setting but that's not really accurate because a random string can fail a high complexify setting. Settings like this can make for infuriating UX. Incidentally, I'm not a fan of vague settings like 'complexify' because it's totally meaningless to the user who is setting the password. For the same number of bytes: opensslrandompseudobytes(16) each byte can have any value (0-255), whereas randomString(16) each byte can only have a-z A-z 0-9 which is 62 combinations per byte. I'm putting together a little module that adds a 'Generate password' button to InputfieldPassword and from my testing it seems you can probably ignore the complexify setting in your EmailNewUser module because when set to the advised range of 0.5 - 1.0 then any randomly generated password seems to satisfy the complexify setting. This might be because the 'complexify factor' is something internal to the JS library used in InputfieldPassword - perhaps difficult or too time-consuming to port to PHP. You can then paste the list of strings in our randomizer and randomize it to determine either who gets the prize (if it just one), or the order in which the prizes are to be given to fundraising participants.RandPass() doesn't support the 'Complexify Factor' setting For example, if you are doing a charity lottery and want to randomly distribute prizes to the charity donors at an event, you can generate a set of unique random strings which can be given out to participants as tokens. While a sequence of random strings can be used for many things, it is often that they find application in games and raffles.

Applications of a random string generator The easiest way to retrieve the list of random strings is to select it all (Ctrl+A on a PC), and then copy it (Ctrl+C on a PC). If that is not what you're going for, then simply change the number of strings field to as many strings as you like (maximum of 10,000) and press the button. If you are doing a raffle, for example, you would want to also flip on the 'Unique strings only' checkbox so that the generator returns a set of unique randomly generated strings. You can use the string generator to produce a set of strings. For example, if the character set is 'a b c d A B C D' and you have selected to both capitalize and to output a unique string, the random string generator may output a string like 'BAC', but it will never output a string like 'BAACB'.įinally, press the 'generate random string' button to essentially perform multiple dice roll with a dice with as many sides as the number of characters entered. Note that using this option and the capitalization option works just as you'd expect - the generated string will contain only unique uppercase letters and any other characters you've elected to use. For example, if the character set consists of 'a b c d' and the resulting string is 'bac', the generator will output 'BAC' if this setting is on.Īdditionally, you can select to get only unique characters in your string. You can remove any characters you don't want, but you need to have at least 2 characters as input.Īfter you've chosen your starting character set, you can select whether the output should be capitalized or not. You can easily input the German, Russian, French, Spanish, or any other characters into the string generator, as well as any symbols you like, other the abovementioned few. Note that you cannot use a comma or a space in the input character set as these, alongside tabs and new lines are used to discriminate between characters.

By default, the generator is loaded with all lowercase and uppercase letters of the English alphabet, the numbers from zero to nine, and a set of special characters including most punctuation signs. 'Alphabet' here means simply the collection (or 'bag') of characters from which the random string generator has to pick randomly. To generate a random string of characters (character sequence), start by specifying which alphabet to use. What is base64encode effect on this kind of binary data, do I actually decrease. mcryptcreateiv seems to return some kind of random binary values, actually used for encrypting/decrypting data with mcrypt library.

Applications of a random string generator I do not know much about cryptography, so I'd like to ask whether this kind of function creates 'good' random values or not.
