How to enable hardware encryption of my intel ssd 660p 1TB?
I can’t find any useful information on the internet.
I hope that the encryption function can be used for theft prevention.
That is to say, if my hard drive is stolen… Continue reading How to enable hardware encryption of intel ssd 660p 1TB?
I have a number of encrypted Duplicati (.zip.aes) files that I used to backup my photos a couple of years ago.
Problem is, I forgot a password for them.
Luckily, the way I did it at the time, I had a randomized 24×24 matrix o… Continue reading Decrypt a Duplicati file with wordlist [on hold]
I have my own stream cipher algorithm, and I made a comparison between it and AES performance. I tested it on several files with different sizes (to 500KB). Its encryption/decryption time is less than AES for files about 500K… Continue reading What is the problem of increasing the time encryption of my stream cipher algorithm? [on hold]
Correct me if I’m wrong at any point of this questino.
I understand that AES is a lot cheaper to compute than RSA (or any form of asymmetric encryption) and that that is why GPG and similar programs (the OpenPGP standard?) u… Continue reading Is GPG’s AES encryption that much stronger than its RSA headers?
My professor has posted a couple of practice questions that so far I haven’t been able to find the answer for and I was hoping you could help.
DES would remain invertible—it would still be ablockcipher—even if its … Continue reading DES/AES invertibility
It is generally said that 2048-bit RSA keys are roughly equivalent to 112-bit symmetric keys and 2048-bit RSA keys are “sufficient for commercial use until around the year 2030” (https://security.stackexchange.com/a/65180/189… Continue reading AES, RSA, ECC Key size
I understand that it is possible to combine symmetric and asymmetric encryption in a way that makes use of the performance of symmetric encryption, and also getting the benefits of being able to separate the knowledge needed … Continue reading How to combine symmetric and asymmetric encryption to encrypt large files?
Google’s Adiantum boosts encryption for low-end devices with processors that do not have hardware support for AES. Continue reading Google Boosts Encryption For Low-End Android Devices
Suppose I have a protocol where fixed-length messages (1280 bytes, no padding) are encrypted with AES in CBC mode. I want to put some data in the message body to verify that the message is authentic. From Wikipedia,
Block… Continue reading Why is authentication impossible with CBC mode?
It has been reported that 7 Zip generates IVs in a weak manner.
What is the actual impact of this? I’m asking about historical Zip files that I’ve sent. I’ve no plans to use 7 Zip going forward until this is fixed.
If I und… Continue reading What is the impact of the reported weak IV in 7 Zip?
