#Free random password generator generator
The period of this random number generator is very large, approximately 16 * ((2^31) - 1). The random() function uses a nonlinear additive feedback random number generator employing a default table of size 31 long integers to return successive pseudo-random numbers in the range from 0 to RAND_MAX. That aside: you aren't calling rand, you're calling random: This is a large and fairly complex topic, so you'll need to do some reading, but asking for random data from an entropy-controlled system source will already be better than using C rand. The larger conceptual problem with this program is that it uses a very cryptographically weak pseudorandom number generator.

This free will never be called delete it. You'll want to run this through an autoformatter, because your if block has wonky indentation and needs more columns to the right. Allocation failure does happen in real life. Allocation failureĪfter calling malloc, always check that you've been given a non-null pointer. What does 95 signify? You'll want to put this in a named #define or a const. If can anyone give me some feedback about it I will be very grateful! PS: I'm new at C programming, that's why I don't know much about pointers and memory management yet. I'm concerned if I allocated the right amount for each string/char array, and if it can break or crash in some future. I have no idea if this is written "the right way" or how it could be better. Finally I've got this working very well based on the outputs below: #include Ĭhar *generate_random_password(int password_lenght, int has_special_characters)Ĭonst char *letters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ" Ĭonst char *special_characters = *random_password = malloc(sizeof(char) * (password_lenght+1)) īut I'm completely in doubt about these strings, pointers, char arrays, etc. LastPass Password Generator is a valuable tool that can help you improve your online security without breaking the bank.I'm making a simple program that generates a random password of some length with or without special characters, just for the sake of learning the C language.
