Detailed explanation-1: -Explanation: Cryptography is the process or mechanism used for converting ordinary plain text into garbled non-human readable text & vice-versa. It is a means of storing & transmitting information in a specific format so that only those for whom it is planned can understand or process it.
Detailed explanation-2: -Encryption is the method by which information is converted into secret code that hides the information’s true meaning. The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.
Detailed explanation-3: -Plaintext is the input to a crypto system, with ciphertext being the output. In cryptography, algorithms transform plaintext into ciphertext, and ciphertext into plaintext. These respective processes are called encryption and decryption.
Detailed explanation-4: -Asymmetric Encryption, also known as public-key cryptography, uses two separate keys for encryption process. One key is a public key and the other is a private key which are linked and used for encryption and decryption.
Detailed explanation-5: -The method of reversing the encrypted text which is known as cipher text to its original form i.e. plain text is known as decryption.
