hash question

I'm trying to reverse engineer a hash and i'm not sure what could product something like this: 931c6ff8d9e365bfb412 the value returned by this system is always 20 chars in length and only consists of letters and numbers. no i have no idea what it is but i'm trying to reverse engineer it to see

I'm trying to reverse engineer a hash ... The whole point of a hash algorithm is that it should not be susceptible to reverse-engineering. That is, given a hash, you should never be able to derive the original value from which the hash was created. If this is in fact the case, the only way to

I don't think you're gonna be able to do that. The whole idea is for it to be undecipherable and not be able to be reverse-engineered. jonese wrote: I'm trying to reverse engineer a hash and i'm not sure what could product something like this: 931c6ff8d9e365bfb412 the value returned by

right i know this and i have some ideas what data is being hashed but i cannot figure out how to limit a hash to only 20 chars. most of the hashing i've even done has been in md5 sha1 etc and this is obviously not that. I know this is a long shot but i was hoping that the 20 char limit might ring

I just googled '20 character hash' and found quite a few sites that talk about such an animal. Might be a good start. -Original Message- From: jonese [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 11, 2006 2:56 PM To: CF-Talk Subject: Re: hash question right i know this and i

If it's 10g, it's very possible they're using dbms_crypto to encrypt some piece of data. You seed it with your own random string of varying lengths. You basically create a wrapper package for the built-in dbms_crypto package. Depending on the length of your seed, you'll get different length
