I would like to understand the difference between:
OpenPGP symmetric encryption
and
AES-256 using Winzip/7-zip?
I mean if you encrypt a file with an OpenPGP program like GnuPG, using AES-256 symmetric encryption. And do t… Continue reading Difference between OpenPGP symmetric encryption and AES-256?
Security protocols such as SSL and HTTPS can encrypt messages with both asymmetric and symmetric encryption.
How are their telecommunication packages arranged? (The parts related to the confidentiality of the message).

How feasible is to brute force the ENCRYPTION key if you have
the clear-text message
the encrypted-version of the same message
you know that Rijandel is the encryption algorithm
you know that the salt is 2 bytes long
I am architecting a passwordless REST API where public/private keys are the primary form of authentication. In order to create a new session you must prove that you hold the private key to the public key tied to the user.
As… Continue reading Security risks on returning encrypted JSON web token without prior authentication
Actual implimentaton will be in android but this is more about general security than actual implimentaton details. I’m making an end-to-end encrypted chat app and I know that in order to send encrypted messages you have to en… Continue reading For encrypted chat app, how can I store sent messages so that they are encrypted but still can be viewed by the sender?
As public key algorithm Elgamal’s cipher text can be re-encrypted using its homomorphic property and can be used in many application i,e Mixnets.
I want some other public key algorithm can behave similarly such that we can r… Continue reading How Asymmetric algorithm’s cipher text can be rerandomized without knowldge of secret key?
I need help on a solution for below scenario from a security perspective.
Scenario:
There are two independent web applications App1 and App2.
User will log in to App1 by performing authentication demanded by App1.
Once authenticated, th… Continue reading Authentication handshake between two independent apps
I’m having a deeper look into OAuth 2.0 and especially the Client Credentials Flow that is intended to authenticate a client application or device without user interaction (the client is accessing its own resources, not actin… Continue reading OAuth2 Client Credentials Flow with assertion JWT: How to share the client’s public key?
Let’s say you have a single sensitive document. You’re traveling to somewhere high risk and are advised not to bring your data, but you also don’t have safe storage at home. So you encrypt your sensitive file and upload it to… Continue reading Is there any sense in encrypting a file for one’s own later use?
I have device connected to scooter it’s 4- wire uart communication. My fear is some can read the ascii data and send the at commands and unlock my scooter and steal the scooter. I want to secure the uart communication between the scooter … Continue reading want to know best way to encrypt the UART communication channel? [closed]
