MFiles.Crypto - error when Decrypt

Question

Hi, 
 trying to use MFiles.Crypto and i run into some erros with decrypt. Maybe i do something wrong, but... 
 for encrypt i use: string pInput = "Message to crypt."
byte[] bytes = MFiles.Crypto.CryptoAES.EncryptString(pInput, "abc"); 
 got something back and it looks like, all ok. 
 I grabbed that crypted string and try to decrypt it like this: string pInputEx = "..saved crypted string..."
string pOutput = MFiles.Crypto.CryptoAES.DecryptString(pInputEx, "abc"); 
 And i got error 
 System.OverflowException: Array dimensions exceeded supported range. 
 
 Any "kick" / help appreciated

Hi Marwin, 
 The M-Files Cryto DLL is not supported for external use. Its purpose is internal, to validate VAF application licences and the like. 
 My suggestion is that you use the standard .NET BCL cryptography namespaces directly if you need to encrypt or hash anything.

 Craig.
