WebAs AES is a symmetric algorithm the same secret key can be used for both encryption and decryption. The expected secret key size we have specified in the key size dropdown So if key size is 128 then "aesEncryptionKey" is a valid secret key because it has 16 characters i.e 16*8=128 bits Decrypt AES Encryption Creating and managing keys is an important part of the cryptographic process. Symmetric algorithms require the creation of a key and an initialization vector (IV). You must keep this key secret from anyone who shouldn't decrypt your data. The IV doesn't have to be secret but should be changed for each session. See more The symmetric encryption classes supplied by .NET require a key and a new IV to encrypt and decrypt data. A new key and IV is automatically created when you … See more .NET provides the RSA class for asymmetric encryption.

WebIn the case of AES it takes a key and then turns a 16 byte block into another 16 byte block deterministically. To encrypt something with a block-cipher you need to use a mode of operation. Typically those modes take an IV (similar to a salt) which should be different for each message you encrypt.

WebAug 26, 2016 · With AES-CBC you usually need a random IV. However, in the case where you use each key only once, like when using password-based encryption with random salts for each file, you can use a fixed, zero IV. So as long as you use a new salt for each file – and even new versions of the same file – you can forgo storing an IV and just use a zero block.
