Private Methods

Method	Description
Base32Encode ( byte data ) : string
EncodeAccountSecretKey ( string accountSecretKey ) : string
GenerateHashedCode ( byte key, long iterationNumber, int digits = 6 ) : string
GenerateHashedCode ( string secret, long iterationNumber, int digits = 6 ) : string
GetCurrentCounter ( ) : long
GetCurrentCounter ( System.DateTime now, System.DateTime epoch, int timeStep ) : long
UrlEncode ( string value ) : string
getHMACSha1Algorithm ( byte key ) : HMACSHA1	Creates a HMACSHA1 algorithm to use to hash the counter bytes. By default, this will attempt to use the managed SHA1 class (SHA1Manager) and on exception (FIPS-compliant machine policy, etc) will attempt to use the unmanaged SHA1 class (SHA1CryptoServiceProvider).
