I am performing a small command line operation the goal is to generate a symmetric key using openssl and store the key in TPM FAPI keystore.
After modifying the symmetric key, the decryption should fail, but it decrypts successfully.

I’m curious about the best encryption algorithm for encrypting my files in 2022? I thought it was a good solution to encrypt my private key with AES-256 but I decided to ask here and choose better algorithm.
If the answer is still AES, whi… Continue reading Strongest symmetric algorithm in 2022 [duplicate]
So, I found a website that uses AES encryption to prevent XSS and I’m wondering if this approach is inherently flawed.
It has an endpoint like execute.php?code=encryptedPayload which de-crypts the payload and directly executes it as JavaSc… Continue reading AES Encryption as XSS protection for url parameters?
I’m using aes-256-gcm encryption. I used a sample key provided in the docs and it works fine.
I also tried a key generated from here and it works fine. There’s no option to specify gcm here yet the key generated works fine.
I’m trying to g… Continue reading Generate AES-256-GCM key
The situation currently is as follows:
All our devices in the same network broadcast their state (alongside with unique IDs) over the network. They also listen in for broadcasts of others. Everything is plaintext.
All the devices have a c… Continue reading How to encrypt peer data exchange?
My VPS is CENTOS 7.
I installed OpenVPN on this vps.
After open it’s admin panel i received this error :

I am trying to better understand the processes involved in e2ee using WebCrypto on the browser.
I understand that the only real method to use a passphrase to generate a symmetric key on the browser is using PBKDF2 using a crypto random sal… Continue reading Can parts of WebCrypto AES-GCM be reused between encryptions
Advanced types of Ransomware generate, usually, an AES 128 bit key (used to encrypt files, some types of ransomware use a unique AES key for each file). This key is generated on the fly. In addition, the ransomware generates a client RSA 4… Continue reading Where is the AES key of ransomware stored (in the file header/trailer)?
How likely is that the developers of Winrar would intentionally implement a backdoor to decrypt every file created by this program?
Can anyone confirm that there isn’t a built-in algorithm in the program to reveal the IV and KEY, for examp… Continue reading Security of Winrar 2022 – backdoors and encryption security
