How does public key decryption work in ensuring secure communication over the internet?
Public key decryption works by using a pair of keys - a public key and a private key. The public key is used to encrypt data, which can only be decrypted by the corresponding private key. This ensures secure communication over the internet because only the intended recipient, who possesses the private key, can decrypt the data. This method helps prevent unauthorized access to sensitive information during transmission.
In asymmetric encryption Both the sender and receiver have a private key and a shared private key?
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.
How do you decrypt a data file to that has been encrypted with the users public key?
When you reference a "public key" you are implying that the file has been encrypted using "asymmetric cryptography". In asymmetric cryptography, encryption and decryption depend on a key PAIR. The user retains their private key and publishes their public key. Anyone can encrypt a file using the user's public key and send it to them. The only person who should be able to decrypt a file encrypted with that public key is the holder of the private key - which, unless the user has made the mistake of sharing their private key - means that only the original user can decrypt the messages sent to them. Most of the asymmetric encryption algorithms use pretty much the same method to decrypt that was used to encrypt, but use the "other" key from the key pair. Messages encrypted using the private key can only be decrypted using the public key - which provides some authentication that the message indeed came from the holder of the private key. Messages encrypted using the public key can only be decrypted by the holder of the private key, so messages sent to them should be secure.
What happens if someone obtains your public key?
If someone obtains your public key, they can use it to encrypt messages intended for you, ensuring that only you can decrypt them with your corresponding private key. Additionally, they can verify your digital signatures, confirming the authenticity of messages you send. However, possessing your public key does not compromise your private key or your overall security, as the public key is designed to be shared openly. It's essential to keep your private key secure, as that is what protects your communications and identity.
The combination of a public key and a private key is known as a?
This is known as RSA encryption. Encryption involving a public and private key combination is known as asynchronous cryptography, as opposed to synchronous cryptography. It is also known as public key cryptography. RSA is an algorithm that may be used (but there are others that can be used), in public key cryptography. (A key pair)

What are the roles of Public and Private Key?
A user's private key is kept private and known only to the user. The user's public key is made available to others to use. The private key can be used to encrypt a signature that can be verified by anyone with the public key. Or the public key can be used to encrypt information that can only be decrypted by the possessor of the private key
What is the file extension used by default for a certifcate file that contains the private key?
*.pfx contains the private key and *.cer does not contain the private key
What is the file extension used by default for a certificate file that does not contain a private key?
.cer for file without private key, .pfx for file with private key
What are some characteristics of asymmetric cryptography?
Asymmetric cryptography, also known as public-key cryptography, involves a pair of keys: a public key, which can be shared openly, and a private key, which is kept secret. This method allows for secure communication and data exchange, as the public key encrypts messages that can only be decrypted by the corresponding private key. Key characteristics include enhanced security, as the private key is never shared, and the ability to authenticate identities through digital signatures. This system is widely used in secure communications, such as SSL/TLS for internet security.
