Here’s a snippet of C# code to do AES encryption.  What is the equivalent in Chilkat? Dim cspRijndael As New System.Security.Cryptography.RijndaelManaged csCryptoStream = New CryptoStream(fsOutput, cspRijndael.CreateEncryptor(bytKey, bytIV), CryptoStreamMode.Write) “Rijndael” is the name of the encryption algorithm, and (essentially) “AES” is Rijndael limited to the choices of 128, 192, or 256 bits. Rijndael/AES is a symmetric block encryption algorithm, and the … Continue reading .NET RijndaelManaged to Chilkat Equivalent
