Password strength symbols, one computes The following table uses this formula to show the required lengths of truly randomly generated passwords to achieve desired password entropies for common symbol sets: People are notoriously poor at achieving sufficient entropy to produce satisfactory passwords. According to one study involving half a million users, the average password entropy was estimated at 40.54 bits. Some stage magicians exploit this inability for amusement, in a minor way, by divining supposed random choices (of numbers, say) made by audience members. Thus, in one analysis of over 3 million eight-character passwords, the letter "e" was used over 1.5 million
Online auction current web environment there are hundreds, if not thousands, of websites dedicated to online auction practices. There are six different basic types of online auctions: In live terms, English auctions are where bids are announced by either an auctioneer or by the bidders and winners pay what they bid to receive the object. English auctions are claimed to be the most common form of third-party on-line auction format used and is deemed to appear the most simplistic of all the forms. The common operational method of the format is that it is an ascending bid auction in which bids are
