To decrypt an encrypted message, you would need the following information:
1. key: This is the secret or private key that was used to encrypt the message. The key is essential for the decryption process because it provides the necessary information to reverse the encryption algorithm and recover the original message.
2. ciphertext: This is the encrypted message that you want to decrypt. The ciphertext is the result of applying the encryption algorithm to the original message using the key.
3. function: This is the decryption function or algorithm that will use the key and the ciphertext to perform the reverse process and recover the original message. The function should be specifically designed to decrypt messages encrypted with the corresponding encryption algorithm.
The output of the decryption process will be:
- decrypted message: This is the original message that was encrypted. Once the decryption function is applied to the ciphertext using the key, it should produce the decrypted message, which is the exact copy of the original message before encryption.
Cryptology: Cryptology is the field of study concerned with the techniques of secure communication in the presence of third parties called adversaries. It encompasses both cryptography (the practice of secure communication) and cryptanalysis (the practice of analyzing and breaking secure communication).
In order to decrypt an encrypted message, pass the encrypted message and the function. (2 points)
