Public Methods

Method Description
DecryptString ( string cipherText ) : string

Decrypt the given string. Assumes the string was encrypted using EncryptString(), using an identical sharedSecret.
DecryptString ( string cipherText, string dataEncryptionKey ) : string

Decrypts the string.
EncryptString ( string plainText ) : string

Encrypt the given string using AES. The string can be decrypted using DecryptString(). The sharedSecret parameters must match.
EncryptString ( string plainText, string dataEncryptionKey ) : string

Encrypts the string.
GenerateEncryptionKey ( int length ) : string

Generates the encryption key.
GenerateMachineKey ( int length ) : string

Generates the machine key.
GetSHA1Hash ( string plainText ) : string

Gets the SHA1 hash.
HexToByte ( string hexString ) : byte[]

converts a hexadecimal string to byte.
TryEncryptString ( string plainText, string &cypherText ) : bool

Tries to encrypt the string. Use this in situations where you might just want to skip encryption if it doesn't work. You should use EncryptString in most cases.

Private Methods

Method Description
GetDataEncryptionKey ( ) : string

Gets the data encryption key.
ReadByteArray ( Stream s ) : byte[]

Reads the byte array.
