Quick Start: Determining encryption type using the web service API

The following C# code example determines the type of encryption that is protecting a PDF document named EncryptLoan.pdf. (See Determining Encryption Type.)

/*

 * Ensure that you create a .NET client assembly that uses 

 * base64 encoding. This is required to populate a BLOB 

 * object with data or retrieve data from a BLOB object.

 * 

 * For information, see "Invoking LiveCycle ES using Base64 Encoding" 

 * in Programming with LiveCycle ES
