👉 Sender computing is a fundamental concept in cryptography that describes the process of transforming plaintext messages into unreadable ciphertext through encryption, while ensuring that only the intended recipient can decrypt and understand the message. This process involves using a cryptographic algorithm and a secret key, known only to the sender and the recipient. When the sender computes the ciphertext from the plaintext using the encryption algorithm and secret key, it ensures that even if the ciphertext is intercepted, it cannot be easily deciphered without the corresponding decryption key. This secure transformation is crucial for maintaining confidentiality and integrity of data during transmission over potentially insecure channels.
