Checking Hashed Passwords with QuickHash-GUI

I found an article recently that showed the use of QuickHash to check password strings and then using the resulting hash in one of the many sites that store hashes of passwords from data breaches. I then also found this article by The Register titled 'Crypto-busters reverse nearly 320 MEELLION hashed passwords' that talks about the same thing in a lot more detail : https://www.theregister.co.uk/2017/09/04/cryptobusters_reverse_nearly_320_meellion_hashed_passwords/ You can read more about Troys work and the concept of password hashes and their availability here : https://www.troyhunt.com/introducing-306-million-freely-downloadable-pwned-passwords where he continues to talk about using the SHA-1 hash of a password to check [...]

Explanation of the current poll question

The current poll is asking users if they would be interested in a code-signed version of QuickHash. Of the votes cast so far, several people have answered with "I don't understand the question" so, I hope to try and make it clearer. In recent times, operating systems like Windows 10, Apple Mac OSX and malicious software detection tools like AVG, Kaspersky, Norton and Windows Defender take a dim view of executable files that are "not signed". What this means is that the operating system cannot be sure sure that the program being run is safe, because it does not [...]

v2.8.3 Removed from Downloads

v2.8.3 had a bug introduced that was not present in v2.8.2 or below and has been fixed in v.2.8.4. The bug related to the text hashing tab. Text was not being hashed correctly due to a change in the code that unknowingly had an adverse effect on the computed hash. Any user who used v2.8.3 to hash text values should re-run their computations using the new version and my apologies come with this. No other part of the program was affected. Due to the severity of this bug, I have removed v2.8.3 from the available downloads to avoid wider [...]

Problem with “Expected Hash Value” in v2.8.3

A user has reported an issue with v2.8.3 (https://www.quickhash-gui.org/bugs/expected-hash-value-report-wrongly-on-single-file-hashing/) regarding a peculiarity with the "Expected Hash Value" field. This field was added a while ago, but another user requested that if the expected hash value is pasted after the file was hashed (whereas it was designed to be input before the file was hashed), the file had to be hashed again in order to compare it to the expected hash value that the user had pasted earlier. So, to fix that, a change was added in v2.8.3 such that if the value was pasted after the file had been hashed, [...]

Base64 Decoding and Hashing Coming Soon

v2.8.3 has been in development for a few weeks and I was about to start thinking about getting it compiled and released, but then one user contacted me with quite a unique and good idea that I hadn't thought of before...Base64 decoding. As you may know, Base64 encoding can be used to convert files like PDF e-mail attachments and picture files into a form of non-binary data that is text based. Base64 is basically groups of 4 text characters that typically ends with an '=' or '==' character. Once decoded, the original file can be used as normal. So [...]

QuickHash forms part of training at Cal Poly in California

From time to time, I like to see where QuickHash has hit the news and tech bloggers. I was delighted to find today (a few weeks after publication I admit) a great and inspiring article at Mustang News (http://mustangnews.net) titled 'How cybersecurity is becoming a hot topic at Cal Poly' written by Brendan Matsuyama. The link to the article is here for those who want to read it in full : http://mustangnews.net/cal-poly-cybersecurity-leader/ and it talks about how the California Cyber Training Complex (CCTC). Key stakeholders in the project include Cal Poly, the California Military Department, local and state law [...]

Manny Fernandez over at Infosec Monkey blogs about QuickHash

I spotted this a little late, but  Manny Fernandez over at Infosec Monkey (http://www.infosecmonkey.com/2016/10/14/quickhash-multi-platform-hashing-tool/) blogged about QuickHash back in October 2016 with a very friendly and detailed description of QuickHash-GUI, and he also gives many reasons as to the scenarios that it can be useful. I only just found it after looking through some twitter posts about the tool! It's surprising how many people have tweeted about it actually :-) A useful read for any prospective user, and I thank the author for the write up.

Michael Bartholow blogs about using QuickHash for encrypting email addresses for Google AdWords Customer Match

It always pleases me to read about QuickHash in the blogs and articles written by other tech folks. Michael Bartholow does so in his article titled "Encrypting Emails for Google AdWords Customer Match". He recalls the story most familiar to many of us...the big corporate licensed tools like Excel and so on failing to do what we can achieve ourselves through open-source development. His blog describes using QuickHash for generating hash values suitable for injestion by Google AdWords. It's a pleasure to get such high praise. Makes you feel like your work is paying off. Perhaps not financially, but [...]

New video to showcase QuickHash-GUI

This evening I recorded a new video of QuickHash-GUI. The former video was a couple of years old now, and despite having quite a lot of views and comments, it showcased what was, in part, some redundant functionality that has since been improved or adjusted. The video is not designed as an authority on the program - merely to show users how they might use it and briefly explain some of the features more easily than reading it. However, the user manual is and always has been quite comprehensive and it details the programs features and strengths and is [...]
