There's some great stuff on ciphers on wikipedia if you're really interested in them. Most of them are nearly over my head.<BR/><BR/>The Microsoft key generating algorithm is set up intentionally to not include metacharacters. I speculate it's by design to make key input easier for the user. <BR/> <BR/>However, the problem with your assessment is that it doesn't address my beef: If the encryption won't accept the characters, YOU'RE DOING IT WRONG. RSA, AES, DES, and a host of other encryption schemes have no problem with anything that you pass them that are all very secure. SSL certificates are generated using one of the major ciphers currently. <BR/><BR/>At any rate, I don't believe that the problem is with the cipher: the characters listed have a high probability of being actual metacharacters in some language. Examples below are all explained in the vein of PERL:<BR/><BR/>$: this is a variable.<BR/><BR/><>: with a filehandle in between (eg, < README >), can be used in place of "read README". <BR/><BR/>&: &SUBROUTINE tells the script to execute the subroutine SUBROUTINE<BR/><BR/>^: used in regular expressions. Tells the regular expression to match whatever is between this and the next delimter at the beginning of the searched string only<BR/><BR/>!: In regular expressions means "not" as in "look for !foo" (not actual code) would return everything that is not "foo".<BR/><BR/>[]: In regular expressions, used to group search items, as in "look for ['foo', 'bar', 'bat']" (not actual code) would return any of foo, bar, or bat.CaptSlaqhttp://www.blogger.com/profile/09765756604461479531noreply@blogger.comtag:blogger.com,1999:blog-11141553.post-11789746221372440742007-05-02T03:30:00.000-04:002007-05-02T03:30:00.000-04:00I large number of programs or sites that require passwords exclude special characters, they want alpha and/or numberic. They may even be case sensitive, but many of them just exclue special characters. I'm guessing that (like the Microsoft product keys, only in reverse) they generate some kind of algorhythm based on the characters, or converts it to a different numerical system, or something. Some means of encrypting it that doesn't allow for special characters. Something new with their SiteKey system?<BR/><BR/>Just a thought, as I'm no coder. I know that special characters make for an even stronger password...Shawnhttp://www.blogger.com/profile/10144700012066449985noreply@blogger.com
