No, both sender and receiver have a private key and a public key. It works like this: if you encrypt something with one key, you need the other to decrypt it. You give everyone a copy of your public key. When they want to send you something encrypted, they use your public key to send it. Only your private key can decrypt it, so no one else can read it. You don't give out your private key.

That is called an IP address.
Encryption (decryption).
It is the Public Key Encryption. A user using the Public Key Encryption has to have both a private key and a public key to send a secured message. The private key is used to unlock both a private and a public key encryption. A public key cannot unlock a private encryption.

From another user: Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric.
The data itself does not matter in this scenario. The type of encryption used is symmetric encryption, meaning that the sender and receiver have the same key to lock and unlock the data.
When data is received by the receiver , receiver send an acknowledgement. After receiving the acknowledgement from receiver , senders knows the message has been successfully sent.
Symmetric encryption is the process of encrypting and decrypting data via a single shared key. The process begins when the sender wants to trasnmit data in a secure fashion. Unencrypted data is ciphered with the shared secret key. The encrypted data is then sent to the receiving host via the internet or local resource. Once the receiver obtains the encrypted data, the receiver uses the same shared secret key to decipher the data. The receiver then has the same exact data unencrypted as the sender. The biggest advantage besides the security is that symmetric encryption is way faster than asymmetric encryption. The disadvantage is getting the shared secret key between the two parties without being tampered with or without being seen/heard by an unauthorized host.
A sender is the individual or entity that initiates and transmits a message or communication. The receiver is the individual or entity that receives and interprets the message or communication sent by the sender. In communication, the sender encodes the message, and the receiver decodes it to understand the information being conveyed.
Private messages are only seen by the sender and the receiver. These messages do not pop up for the public.
sender is to deliver or give message while the receiver is to receive a message from the giver or sender.
The idea that both the sender and receiver are responsible for listening is called
A receiver attacker is a type of cybersecurity threat where an attacker intercepts or captures data transmitted between a sender and a receiver. This attack can lead to sensitive information being stolen or manipulated by the attacker. It is important to implement encryption and secure communication protocols to protect against receiver attacks.
