Detailed explanation-1: -In asymmetric key cryptography, the private key is kept by one public key and one private key-to prevent unauthorized entry or usage. Anybody can use a public key to encrypt a document so that only the expected receiver can decrypt it with their private key.
Detailed explanation-2: -Asymmetric encryption involves two keys, private and public. Something encrypted with one can only be decrypted with the other. There is no shared key. A message encrypted with a key can not be decrypted with the same key.
Detailed explanation-3: -Asymmetric keys are the foundation of Public Key Infrastructure (PKI) a cryptographic scheme requiring two different keys, one to lock or encrypt the plaintext, and one to unlock or decrypt the cyphertext. Neither key will do both functions. One key is published (public key) and the other is kept private (private key).
Detailed explanation-4: -Decryption Key. It is a value that is known to the receiver. The decryption key is related to the encryption key, but is not always identical to it. The receiver inputs the decryption key into the decryption algorithm along with the ciphertext in order to compute the plaintext.
