| Just for your interest/discussion. I have found a freeware program that quickly changes a user's small, easily remembered password into a more formidable one. You simply type in a short password into a password box, highlight it, and then press F8 (any Fn key can be chosen). The short password is then changed into a salted (you provide the string to salt it with) MD5 equivalent with the ability to choose the outcome length (8 - 32). I have a password that I always use and alter it with the same criteria that I get from each website. The program can be found here: http://cdn.simtel.net/pub/simtelnet/...SSOverride.zip |

| Is it Windows only?? That would be a vulnerability in itself. |

Look at this one: Mhallifwwas Too hard to remember you say? C'mon, gimmee a break! That's crap! It's easy to remember it. That string is crafted from the FIRST character in EVERY word of: Mary ha a little lam it's fleece was white as smow Mix it up a little! Use Lh2ddtewpah? It contains a nomner and a question mark. Sound aecure? It should be. It stands for Larry had 2 dozen dogs their ears were pink as hell? That approach too tough for you folks? How about Txtojlwftbd That's the FIRST character of EVERY word found in the nonsensical sentence The xray taken of Jim's leg was found to be defective I think I can safely bet my life that none of those strings can be guessed or found n a dictionary anywhere in the world. Surely EVERYBODY out there can come up with a nonsensical phrase or sentence that can be used in the same way. Choose one that contains a numerical digit and at least one punctuation character. Do that and you will be able to remember the most riduculous strings imaginable. Em |

Taking just that last example: It would be found in a brute-force search of alpha characters and has an entropy of about 63 bits. Not bad, but nowhere near the inherent strength of the 128- or 256-bit algorithms, themselves. What I find especially odd, though, is this: If you take the stated entropy of English, you find that the original, full-written-out, 53-character passphrase has a LOWER entropy than that 11-character passphrase. >Surely EVERYBODY out there can come up with a nonsensical phrase or >sentence that can be used in the same way. Choose one that contains a >numerical digit and at least one punctuation character. Do that and >you will be able to remember the most riduculous strings imaginable. That helps quite a bit, but even adding numbers and up to 20 possible marks brings you up to only 70 bits of entropy. The OP's technique allowed for up to 128 bits, *and* (with the salt) the need to remember only one passphrase to generate different passwords for every use. You could increase your entropy by increasing phrase length. The OP can't improve beyond 128-bit except by doing it twice with different phrases. Of course, now that he's blabbed his technique, it's not as strong as it used to be. (For him, that is. It's quite strong for anyone else.) As a general rule, using *one* password-generating technique, and telling people what that technique is, has to give crackers clues to reduce their search's key space size. -- Arthur T. - ar23hur "at" intergate "dot" com Looking for a z/OS (IBM mainframe) systems programmer position |
