메소드	설명
AnotherAES ( string key )	Initialize algo just with key Defaults for RijndaelManaged class: Block Size: 256 bits (32 bytes) Key Size: 128 bits (16 bytes) Padding Mode: PKCS7 Cipher Mode: CBC
AnotherAES ( string key, int blockSize, int keySize, PaddingMode, paddingMode, CipherMode, cipherMode )	Initialize algo with key, block size, key size, padding mode and cipher mode to be known.
Decrypt ( Array, cipherText, Array, IV ) : string	Based on https://msdn.microsoft.com/en-us/library/system.security.cryptography.rijndaelmanaged(v=vs.110).aspx
Dispose ( ) : void	Dispose RijndaelManaged object initialized in the constructor
Encrypt ( string plainText, Array, IV ) : byte[]	Based on https://msdn.microsoft.com/en-us/library/system.security.cryptography.rijndaelmanaged(v=vs.110).aspx Encrypt a string using RijndaelManaged encryptor.
GenerateEncryptionVector ( ) : byte[]	Generates a unique encryption vector using RijndaelManaged.GenerateIV() method
GetUniqueString ( int numBytes ) : string	Based on http://stackoverflow.com/a/1344255 Generate a unique string given number of bytes required. This string can be used as IV. IV byte size should be equal to cipher-block byte size. Allows seeing IV in plaintext so it can be passed along a url or some message.
StringToByteArray ( String hex ) : byte[]	Based on http://stackoverflow.com/a/311179/1541224 Converts a string to byte array. Useful when converting back hex string which was originally formed from bytes.
