Understanding advanced encryption standard on basic level doesn’t require a higher degree in computer science or Matrix-level consciousness — let’s break AES encryption down into layman’s terms Hey, all. We…

Is PBEWITHSHA256AND128BITAES-CBC-BC known to be outdated or is it considered robust?
Is it sufficient in applications that need to protect PII?
Thanks.
If I use a database encryption package for oracle like dbms_crypto, would this be vulnerable to any attacks? I know that it uses algorithms like 3DES, AES, etc. These are all thigns that you can use while using this package, and there are … Continue reading Are encrypted databases secure against all attacks?
I’m building a Spring app and a React app which also contains Chat functionality. I use WebSocket with RabbitMQ as message broker.
I store the chat history as encrypted messages with AES, and before I send them to the client, I decrypt t… Continue reading Can GET Requests with Spring Rest controllers be intercepted by attackers?
I was considering developing an application level software for file encryption after stress testing many of my implementations of popular symmetric ciphers. I would love to support multiple algorithms like AES (GCM / CBC/ CTR) , XChaCha20… Continue reading Is AES the recommended symmetric cipher for production level software?
I am writing my master’s thesis about WLANs, and there is something what I don’t really understand. This may be a dumb question but I didn’t find a clear explanation.
WPA uses encryption TKIP. WPA2 uses encryption AES. So far so good. What… Continue reading Does WPA2 use TKIP or not?
I just learned AES-CTR.
I am wondering about the security of the CTR mode. It is basically an AES of the nonce with an XOR-Encryption at the end.
Are this 2 assumptions correct?
The nonce doesn’t have to be random, can also be 0 for ex… Continue reading CTR: Why not XOR before AES
The AES-GCM algorithm provides not only confidentiality but also integrity. I understand that integrity is an important part of security in overall, but whenever I think in terms of possible attacks, only attacks against encryption in tran… Continue reading Integrity attacks and encryption at rest
Is there a way to encrypt files with AES 256 in the authenticated GCM mode using GPG?
I don’t see GCM in supported cipher modes. It seems that the GPG uses only one mode (its own modification of CBC), although libgcrypt supports GCM.
Let’s suppose we have the plaintext, 14/16 char of the key and the first 2 and the last 36 chars of encrypted data (that is 64 char long). What I want is to find the IV. The cipher algorithm is AES (I think 128).
As I said, both the Key a… Continue reading Finding IV in AES-128 having partial Key and plaintext
