WebFeb 7, 2024 · Decryption is the process of converting ciphertext back to plaintext. To encrypt more than a small amount of data, symmetric encryption is used. A symmetric key is used during both the encryption and decryption processes. To decrypt a particular piece of ciphertext, the key that was used to encrypt the data must be used.

WebSo you can decrypt each block by performing the block decrypt, and then XOR-ing with the previous ciphertext block, giving you a plaintext block. This can be performed for each block, with the possible exception of the first block, for which you need the IV. If you don't know you can try and guess the IV. peace in kiswahiliWebText Encryption Encryption is the process by which a readable message is converted to an unreadable form to prevent unauthorized parties from reading it.
