It's not as hard as you might think, at least in terms of 32-bit fingerprints: https://evil32.com/ -- Pete Stephenson On Mon, Jun 19, 2017, at 08:00 AM, Lou Wynn wrote: > According to my understanding of crypto theory, your only way is to > generate keys and compare their fingerprints and with th

Google is a pretty great tool for this kind of things. Here is one of the results I found: https://github.com/Valodim/pgp-vanity-keygen As far as I can tell from the source, it uses the method I suggested, decreasing timestamp one by one, and it finds a fingerprint that ends in a given string of b

Hi everyone Thanks for your input so far. I am surprised to learn about the suggested methods. For my example 1, I had assumed there would be only (1/16)^4 combinations so it should be fairly quick (i.e. less than a week to find one). Let say for now, I just want my full fingerprint to start with

The easiest strategy, of course, is to simply use gpg to generate a key and check its fingerprint until you get the one you need (see batch mode). Generation of an RSA 2048 key is taking around a second, so e.g. for your example #1 (four bytes fixed) we are talking tens of hours or ones of days. I

According to my understanding of crypto theory, your only way is to generate keys and compare their fingerprints and with the value you want. I would be surprised that you can find one in your lifetime. Or it'd be a breakthrough in cryptography if you managed to do it somehow. Thanks, Lou On 06/1

Creating Unique Fingerprint

2017-06-18 Thread Long Si
Hi I am on Linux, and would like to generate a key with "unique 40" fingerprint. eg 1: Starts with ABCD ... eg 2: Starts with AXXX ... XXXA ends with A eg 3: ... without any '0' character at all How would I go about writing such a script? Don't mind running for months
