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.

WebMar 5, 2015 · AES encryption only supports 128-bit (16 bytes), 192-bit (24 bytes) or 256-bit key (32 bytes) lengths, so we'll need to create or generate an appropriate key. For simplicity, let's create a simple byte array of ascending numbers. We'll use a 128-bit key, so we'll need a 16-byte array. Long way Web256-bit AES keys. – When using an Approved DRBG to generate keys or FFC domain para meters, the requested security strength of the DRBG must be at least as great as the security strength of the key or domain parameters being generated.
