Detailed explanation-1: -There are two types of encryption in widespread use today: symmetric and asymmetric encryption. The name derives from whether or not the same key is used for encryption and decryption.
Detailed explanation-2: -Asymmetric cryptography uses two keys, one to encrypt and the other to decrypt. Hashing is a one-way cryptographic transformation using an algorithm, but no key.
Detailed explanation-3: -Most internet security (IS) professionals break down encryption into three distinct methods: symmetric, asymmetric, and hashing.
Detailed explanation-4: -In asymmetric, or public key, encryption, there are two keys: one key is used for encryption, and a different key is used for decryption. The decryption key is kept private (hence the “private key” name), while the encryption key is shared publicly, for anyone to use (hence the “public key” name).
