Public key encryption is the process of encoding messages in such a way that eavesdroppers or hackers cannot read the message but that authorized parties can. It uses two keys at the same time, a private key that is only known to your computer and a public key that your computer gives to another computer wanting to communicate with the former. Without both keys, the messages cannot be read. Both keys are based on prime numbers making this system extremely secure and popular because essentially there is an infinite number of prime numbers available, meaning a nearly infinite possibilities for keys.
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, Public key cryptography is safer than Private key Cryptography. In public key cryptography only only one part of key is visible to others.
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.
Asymmetric encryption employs the use of public/private key pairs.
One of the most popular programs is PGP (Pretty Good Privacy) This uses a private key and a public one. Of course any encryption can be broken given enough time.

Public-Key Encryption RSA Technology
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)
