Hashing Unicode Text Strings

In my previous blog article, I described the use of QuickHash to hash password strings for use on the various data breach checking websites. A user contacted me to ask about Unicode characters and whether QuickHash can hash Unicode strings, like passwords that may contains German Umlauts and so on. Whilst it is not that common for such characters to be used in passwords, they sometimes are, depending on the application. And the answer is yes - QuickHash will generate a hash of a Unicode string no problem. As you can see in the screenshot below, if I type [...]

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 [...]

QuickHash v2.8.4 for Apple Mac OSX

QuickHash v2.8.4 for Apple Mac OSX is now available from the downloads section. It should hopefully just run when the app is extracted from the zip file, but you may need to adjust the security settings of your OSX system to allow it to run, as it is not signed. https://13.221.33.129/downloads/ In the future, I may provide signed versions of the program depending on the results of the current poll which is to establish how many people would like a signed version of the program.

v2.8.4 Released

Today I have released v2.8.4 of QuickHash. It includes only a few fixes but they are significant. See the Changelog for more details, but in summary, it includes several important fixes to the Expected Hash Value field in the "File" tab, and it corrects (reverts) a previously accepted change for the "Text" tab, such that strings were not being hashed correctly. That was also fixed. The user manual has not been changed other than the first page as no instructional adjustments have been added. https://13.221.33.129/downloads/ I hope to buy a code-signing certificate soon, so there may be digitally signed [...]

Problem with “Expected Hash Value” in v2.8.3

A user has reported an issue with v2.8.3 (https://13.221.33.129/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, [...]

v2.8.3 Is Out Now (for all operating systems)

v2.8.3 of QuickHash is now available for Windows, Linux and Apple Mac OSX users. This version should, arguably, have been v2.9.0 because, for the first time in years, a new tab has been added offering a complete range of Base64 decoding. There's lots more improvements too. See the release notes and user manual for full details, but very briefly the user can hash a Base64 encoded file (or a folder of such files) and have the encoded and decoded hash values computed, without the user having to manually do the decoding. There's also a useful button that simply decoded [...]
