WebNov 14, 2024 · The AES doesn't change the size, and the ciphertext size is equal to the cleartext size. Also, in ECB and CBC modes, we should use a padding algorithm like PKCS 5. So the size of data after encryption is: ciphertext_size (bytes) = cleartext_size + (16 - (cleartext_size % 16)) For storing IV with ciphertext, we need to add 16 more bytes. 4. … WebJan 8, 2013 · When you create an object in a SQL Server database and specify WITH ENCRYPTION SQL Server does two things to prevent spying eyes from getting to the plaintext object definition.
