Random code generator

**What is?** Algorithm to Randomic output generator generic with characters from a given alphabet by using permutations (<[login to view URL]>). ## Deliverables What is? Algorithm to Randomic output generator generic with characters from a givenalphabet by using permutations ([login to view URL]). Handy tool for Information Retrieval. Where will be used? These codes will be printed on folders to set of people. The main idea is: a user with a code on his hands cannot change just one or two letters and guessing other code. It is a security matter: follows some bullet points regarding security aspects: · Setting a number of jumps: In all possibilities of permutations we have to be able to jump between a generation and another. · Verification digits, the idea is to generate a secure random code with one or more digits of verification. Just an item to improve security of code. · Similarity: we have to think how to avoid the similarity between codes. We are accepting ideas about this. Features - In config file we must be able to: o Set the possible characters that will be available for generating the random codes; o Total amount of characters the random codes, ie, How many positions my universe of “random codes?? will have, for example 10 positions; o In some cases I need to specify a prefix at the beginning of random codes. In most of the cases, it has 2 or 3 positions, it would be great that we can be able to set the number of positions this prefix would have, sample: “X1?? all generated code will have this prefix, is not have be related with algorithm.
