Can the user get the private key from the encrypted and the plaintext data or does it make it easier for an attacker?

What encryption protocol is Kleopatra using to protect the private key?
I checked PGP RFC document and found out different protocols can be used, it’s up to the software developer.
Has anyone be able to find what symmetric encryption proto… Continue reading What encryption protocol is Kleopatra using to protect the private key?

ArchLinux wiki page on GnuPG reads
Once a key has been submitted to a keyserver, it cannot be deleted from the server.
Does that mean that also the expiration date with which I published the key via gpg –send-keys key-id cannot be chang… Continue reading Can I change expiration date of a gpg key I’ve already sent to a key server?
I was watching this short video and apparently every time users open an HTTPS connection, a handshake between client & server happens. They interchange the public keys, keeping the private keys.
On each side, the public-private key pai… Continue reading Difference between Symmetric and Asymmetric encryption
I’d like to set up a remote backup for my PC. I want to have it run at scheduled times, encrypting the data locally and then transmitting it to the server. I’d like to use something popular and open source (like veracrypt), but most of tho… Continue reading Asymmetric Encrypted Container
Different companies seek permission to start and run, from our organization. I am approval or permission-giving authority. I am having an inspector who goes to different places and visits companies and does inspection. Depending upon the c… Continue reading Deciding the kind of key required for implementation of monitoring software
Can a KMS manage an Asymmetric Keypair on another platform?
i.e. the keypair has expired its effective crypto period and needs to be replaced by a new key pair.
And if so how is this done?

The Web Authentication API allows websites served via HTTPS to allow users to authenticate via asymmetric encryption. The procedure for login is basically the following:
Server sends a challenge (16 random bytes);
Client signs the challen… Continue reading What are the benefits of using WebAuthn?
Let’s say I want to make an encrypted message app (just an example). So, I will need a user1 with a password1, private key1 (that will be encrypted with the password1), public key1 (that will depend on private key1), and the data1 (that wi… Continue reading Changing private key in asymmetric encryption and recovering data
