Generally, it uses a key that is known to both the sender and the receiver so that they can cipher and decipher the text. Encryption is converting the text into a secret message, technically known as converting the plaintext to ciphertext and Decryption is converting the ciphertext back to plaintext so that only the authorized users can decipher and use the data. The ciphertext is a data or text which is encrypted into a secret code using a mathematical algorithm, it can be deciphered using different mathematical Algorithms. If I need to send my personal details to someone over mail, I can convert the information using Encryption techniques and send it, on the other hand, the receiver will decrypt the information received using Decryption Techniques and there will be no data tampering in between. It involves the process of encrypting and decrypting the data, for eg. It works on different mathematical concepts and algorithms to transfer the encoded data into a secret code which is difficult to decode. Cryptography is a process which is mainly used for safe and secure communication.
