Hi guys,

I need to generate a 25 character key from a password

The password may be any ASCII character, and must be greater than 5 characters in length.
The key must be all letters and numbers, and exactly 25 characters in length

I want it to be repeatable, if I type in this password I get this key again.

Has anyone done this or have any pointers for me?

Thanks,
Dave

that cant be that hard, well it can take some time. I will construct a tiny version for you:







You get the idea how I would have done it Ask Verrigan, he is the perfect man for the job when it comes to these things

Well i would assume that you could do something like... get the length of their password, and then start to generate one based on that. if you want it to be a repeatable key... then a mathematical formula obviously is what needs to be used.

I agree with obsidian. Generate the length through the length of the password, then use a formula to fill it with stuff.

Well, I don't want it reversible either. I want something like an MD5 with 25 characters.

Why 25 characters? I've always wished MD5 was easily definable on the length, too - god that would be handy. But with 25 characters, in base 16, that is still 16 ^ 25, or 1267650600228229401496703205376 different combination, so chances of repeats are quite small.

Anyways, what you can do is just take the MD5 hash and trim off the last 7 characters, and bam, 25. If you want to obfuscate it farther, run whatever you can/want through encryptions, combine different parts of MD5 hashes, etc.

Ok I decided what I am going to do.

I need 4 different 25 character keys, so I am going to generate 5 MD5 values, doing some boolean modification between each one, and then take 5 characters from each one.
