Length cryptoStream. ToArray memoryStream. Close cryptoStream. GetBytes saltValue ' Convert our ciphertext into a byte array. FromBase64String cipherText ' First, we must create a password, from which the key will be ' derived. This password will be generated from the specified ' passphrase and salt value. The password will be created using ' the specified hash algorithm. Password creation can be done in ' several iterations.

Specify the size of the key in bytes instead of bits. Use default options for other symmetric key parameters. CBC ' Generate decryptor from the existing key bytes and initialization ' vector.

Key size will be defined based on the number of the key ' bytes. CreateDecryptor keyBytes, initVectorBytes ' Define memory stream which will be used to hold encrypted data.

Read ' Since at this point we don't know what the size of decrypted data ' will be, allocate the buffer long enough to hold ciphertext; ' plaintext is never longer than ciphertext.
