Symmetric key extensions

Symmetric encryption and decryption is done using RijndaelManaged provider. The provider is configured to use CBC mode and PKCS7 padding. A random IV is generated each time and attached to the cipher data. The key used in the symmetric encryption is a hash of key provided using a random salt generated using Rfc2898DeriveBytes. The random salt is stored in the cipher data, the hash is generated using a high number of iterations (>1000)
