Pretty straightforward question. Take the image here:

Does it come with a checksum, which I can verify against after I have fully downloaded the file?
This question goes for any file downloaded, and in my pa… Continue reading Do all files downloaded from the web, come with a checksum to verify the file?
Consider the following scenario. A company has several computers for each users on the same domain. They purchase an RSA certificate from a recognized authority which will be deployed with private / public key on all workstations. So all t… Continue reading Use the public key of a certificate as the key for HMAC SHA
I’m trying to implement the putty file format in one of my dart packages. Implementing the actual key loading was ok, but I’m struggeling with the mac validation. I’m not shure what I’m doing wrong here
The putty code is quite clear about … Continue reading Need a test vector for the putty ssh-2 file mac validation
When using Remmina in Ubuntu connecting to Windows remote desktop, a message about a mismatch of certificates get displayed. However, Remmina is displaying it in SHA256 format. But when I look at the certificate in Windows, it’s displaye… Continue reading How to make Remmina or freerdp display matching Windows remote desktop certificate thumbprint in SHA1? Or Windows to display it in SHA256?
How to brute crypt I already know kind of. For example I know that it gonna be five numbers separated by dashes (like "1-2-3-4-5"), but I don’t have any idea the way it was crypted. Unless it was some of the SHA hashes.
Can you r… Continue reading How to brute crypt with unknown hash?
I was wondering if I compare SHA-256 of two binaries with same version on different machines, results will be two identical checksums.
I tried this on ssh on macOS (Catalina). (I checked that ssh -V produce exactly same version)
And tested… Continue reading Different SHA256 checksum of same version of ssh binary on different machines
The security branch of my company worries that the use of older versions of OpenSSH (pre-7.4), where the only Key Exchange Algorithm available is SHA-1 is a major security issue. They suggest generating new public/private keypairs for all … Continue reading How does the weakness of SHA-1 introduce attack vectors in SSH?
I happen to have a few hashes generated with code that did this (it has been changed to use a more "standard" bcrypt call):
$ python3
>>> import hmac
>>> hmac.new(b’The quick brown’, b’123456′, digestmod=’sha1′)… Continue reading cracking HMAC-SHA1 when the password and seed are inverted
Every hacker gathering needs as many pixels as its hackers can get their hands on. Get a group together and you’ll be blinded by the amount of light on display. (We propose “a blinkenlights” as the taxonomic name for such a group.) At a large gathering, what better way to …read more
With the roughly 20-day wide launch window for the Mars 2020 mission rapidly approaching, the hype train for the next big mission to the Red Planet is really building up steam. And with good reason — the Mars 2020 mission has been in the works for a better part of …read more
