WebNov 18, 2024 · In this article. Decryption is the reverse operation of encryption. For secret-key encryption, you must know both the key and IV that were used to encrypt the data. For public-key encryption, you must know either the public key (if the data was encrypted using the private key) or the private key (if the data was encrypted using the public key). WebThey are located in the Encrypt/Decrypt menu section. Observations In order to make this observation, I opened Cryptool, created a new file, and saved it using my college credential email address.
