Signal developer Moxie Marlinspike criticized early encryption software’s user-unfriendly design at Black Hat 2024, admitting he and others initially failed to consider non-technical users’ needs. Speaking with Black Hat founder Jeff Moss, Marlinspike … Continue reading Signal Developer Explains Why Early Encrypted Messaging Tools Flopped
when i check connection status with google services (gmail for instance) i see that connection is secure. Then I can check certificate details. Chrome shows that it uses 3 different certificates with different public keys.
Hierarchy:
GTS … Continue reading Why chrome shows several certificates for encryption?
I have a LUKS encrypted file filled with around 160GB of data that I use a lot. For safety, I created the file with 400GB. That is of course a lot of wasted space. So I switched to a sparse file, basically following the advice here, simply… Continue reading Encrypted LUKS fs inside a file: sparse or not?
Apple’s open-source “swift-homomorphic-encryption” package revolutionizes privacy in cloud computing. It allows computations on encrypted data without decryption, safeguarding… Continue reading Apple Unveils Homomorphic Encryption Package for Secure Cloud Computing
I apologise in advance if this is a dumb question. But this seems like one of those straight forward things that are so straight forward that its not even mentioned and I am not getting it.
Perhaps I am too used to the simplistic client / … Continue reading How does JWE secure the Content Encryption Key
We are all used to reading web pages protected by HTTPS. It has, as far as I (as a user of a browser) can perceive, zero cost. Contrarily, encrypting an email is inconvenient to both sender and receiver.
When I attach a sensitive pdf encry… Continue reading Why is much harder to encrypt emails, compared to web pages?
I accidantally formatted the entire hard disk (quick format into NTFS)
it contains multiple partitions of different filesystem
ext4 encrypted with luks (whole partition encryption)
ext4 no encrypted
ntfs not encrtpted
I restored partitio… Continue reading Restoring lost encrypted partition [migrated]
This isn’t good:
On Thursday, researchers from security firm Binarly revealed that Secure Boot is completely compromised on more than 200 device models sold by Acer, Dell, Gigabyte, Intel, and Supermicro. The cause: a cryptographic key underpinning Secure Boot on those models that was compromised in 2022. In a public GitHub repository committed in December of that year, someone working for multiple US-based device manufacturers published what’s known as a platform key, the cryptographic key that forms the root-of-trust anchor between the hardware device and the firmware that runs on it. The repository was located at https://github.com/raywu-aaeon/Ryzen2000_4000.git, and it’s not clear when it was taken down…
Computers blue-screen-of-death around the world! The Paris Olympics is at risk of attack! And the FBI pull off the biggest sting operation in history by running a secret end-to-end encrypted messaging app! All this and much much more is discussed in th… Continue reading Smashing Security podcast #382: CrowdStrike, Dark Wire, and the Paris Olympics
I’m building a PHP website using MySQL as a database for an event managing system. I want to store user data so when they sign up for an event they can just verify information and submit, rather than re-inputting the information over and o… Continue reading How do I encrypt and store user data?
