When implementing JSON Web Encryption (JWE), I understand the reasons why you might choose A256KW over DIR. But, now I notice there is also A256GCMKW as an optional part of the JWE standard (see RFC7518 page 19 which defines it in detail, … Continue reading Is there any reason to choose A256GCMKW over A256KW in JSON Web Encryption?
Consider the following use case:
User can choose a key.
The key is used to encrypt files to be stored on a server.
Some file and directory names are easily guessed from the nature of the software, some are not and those shall be encrypted… Continue reading Encryption to use when limited data for a chosen plaintext attack is available
I am learning about how AES encryption works. I understand the overall process, but I think I’ve missed something. Let’s say I have this text to encrypt:
"vulkanski izbruh" – 16 characters (15 letters, 1 space)
And this is my pri… Continue reading AES-256 Encrypted Text Differs [closed]
In BearSSL webpage it has been claimed that bearssl supports AES/GCM
BearSSL currently implements AES/CBC, AES/GCM, AES/CCM and 3DES/CBC cipher suites.
But I can not find any function in its GitHub repository. Do I’m searching in the wro… Continue reading Does bearssl contain AES-GCM implementation?

I’m currently developing a backend service where I need to encrypt sensitive data stored in a database. I’m planning to use the AES-GCM (Galois/Counter Mode) encryption algorithm for this purpose.
My Approach:
Single Encryption Key: I int… Continue reading Is it Secure to Use a Single AES-GCM Encryption Key for an Entire Database if Unique IVs and Tags Are Generated?
Starting from a known nonce, AES GCM uses a counter to sequentially generate new numbers that are the input to the encryption function. If by chance two nonces from two distinct runs of AES GCM were close enough together such that their co… Continue reading In AES GCM, would using different nonces that are close reveal data?
I’m not a security expert, so please excuse this question if it’s silly, but I would really like an answer. I am using AES GCM to encrypt and would like to combine the randomly generated nonce with the ciphertext for convenience.
What’s an… Continue reading What’s a good way to append a nonce to ciphertext in Python for AES GCM in Python?
I remember about 90% of my password used for encrypting the persistent user data file system (stored as knoppix-data.aes) while setting up Knoppix a few years ago and would now like to explore the feasibility of a dictionary brute-force at… Continue reading Any information on the encrypted Knoppix user data file system (knoppix-data.aes)?
