The public key concerning the CAC refers to the authorized key that is open to all the concerned people. The encryption procedure ranges according to the key.
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)
Public key cryptography always works the same way: Encryption is done with the public key, decryption done with the private key. It is not possible to decrypt anything with the public key (otherwise the whole system would crash down). The only time it's done the other way is for message authentication, where only a digest of a message is encrypted and can be verified (not decrypted) using the public key.
Yes. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
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.
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.

You be referring to a CAC Card. This was a common access card, also used for computer security by the DoD and military that doubles as an ID Card in some cases. It's used for PKI (Public Key Infrastructure) encryption key holding as well in some cases.

What happens when a CAC is terminated
If data is encrypted with the public key, only the private key can decrypt itAnswer Explanation: Public key encryption uses an asymmetric algorithm, which uses a public key and private key combination for the encryption and decryption process. If data is encrypted with the public key, only the private key can decrypt the data. The public key cannot decrypt a message that was encrypted with the public key. Alternatively, if data is encrypted with the private key, only the public key can decrypt the data.
