WEP key strength (key length) is sometimes confusing because, although there are only two widely accepted standard lengths, 40-bit and 104-bit, those lengths are sometimes confused by adding the 24-bit IV (initialization vector) counter to the length, resulting in 64-bit and 128-bit total key lengths. Still, ANY encryption is better than no encryption. If some of your WiFi network cannot support the newer and much stronger (effectively unbreakable when used with maximum-entropy keys like these) WPA encryption system, you'll be forced either to run two WiFi networks in parallel (which is totally feasible one super-secure and one at lower security) or to downgrade your entire network to weaker WEP encryption. Using fewer hex characters for WEP encryption: If any device did not support this mode of specification (and most do not) it would not be able to join the network. This is a precise means for supplying the WPA keying material, but it is ONLY useful if ALL of the devices in a WPA-protected WiFi network allow the 256-bit keying material to be specified as raw hex.

Some WPA-PSK user interfaces (such as the one in Windows XP) allows the 256-bit WPA pre-shared key to be directly provided as 64 hexadecimal characters. So there is no underlying similarity in the data among the various format passwords.ġ7DEF637839342F4D509083D6600627372F3EC2EF6D27FA59615A92F735DFFB4Įach of the 64 hexadecimal characters encodes 4 bits of binary data, so the entire 64 characters is equivalent to 256 binary bits which is the actual binary key length used by the WiFi WPA pre-shared key (PSK). Each of the password strings on the page is generated independently of every other, based upon its own unique pseudo-random binary data. The raw password material is provided in several formats to support its use in many different applications. In other words, these password strings are as random as anything non-random can be.
The deterministic binary noise generated by my server, which is then converted into various displayable formats, is derived from the highest quality mathematical pseudo-random algorithms known. Electrical and mechanical noise found in chaotic physical systems can be tapped and used as a source of true randomness, but this is much more than is needed for our purposes here. There are ways to generate absolutely random numbers, but computer algorithms cannot be used for that, since, by definition, no deterministic mathematical algorithm can generate a random result. The "pseudo-randomness" of these numbers does not make them any less good. I use the output of this page myself for any purpose, without hesitation, any time I need a chunk of randomness because there is no better place to find anything more trusted, random and safe. Throughout this page I use the shorthand term "random" instead of the longer but more precise term "pseudo-random". The "Techie Details" section at the end describes exactly how these super-strong maximum-entropy passwords are generated (to satisfy the uber-geek inside you).Ī note about "random" and "pseudo-random" terminology: The "Application Notes" section below discusses various aspects of using these random passwords for locking down wireless WEP and WPA networks, for use as VPN shared secrets, as well as for other purposes. Each set displayed are totally, uniquely yours - forever. You may safely take these strings as they are, or use chunks from several to build your own if you prefer, or do whatever you want with them. No one else can ever see them or get them. Therefore, these password strings are just for you.
