We are happy to announce that version 1.7.4 of DidiSoft OpenPGP Library for .NET has been released.
Among the new features provided with this version is support for Silverlight and methods for inspecting the type of an arbitrary OpenPGP archive.
Unfortunately in this version we had to make obsolete the PGPLib class method EncryptStream that has no file name label parameter. This is due to the great misunderstanding and problems that some of our existing customers have faced when encrypting large files with it. The problem is that for example McAfee E-Business server cannot decrypt large files encrypted with this method, because it encrypts the data ‘just for reading’ (‘for your eyes only’).
To achieve the same functionality (encrypt ‘for your eyes only’) please use the overloaded methods that accept a second file name label parameter where you can pass the new constant PGPLib.CONSOLE.
Below is the complete list of the changes in this version:
[*] : Bug
