<para>This class provides access to the Data Protection API (DPAPI) available in the Windows XP and later operating systems. This is a service that is provided by the operating system and does not require additional libraries. It provides encryption for sensitive data in memory.</para>
|
|
<para>The class consists of two wrappers for the unmanaged DPAPI, <see cref="M:System.Security.Cryptography.ProtectedMemory.Protect(System.Byte[],System.Security.Cryptography.MemoryProtectionScope)" /> and <see cref="M:System.Security.Cryptography.ProtectedMemory.Unprotect(System.Byte[],System.Security.Cryptography.MemoryProtectionScope)" />. These two methods can be used to encrypt and decrypt data in memory.</para>

<para>This method can be used to protect data in memory. Note that the method does not make a copy of the data, but encrypts the byte array in place. The <paramref name="userData" /> parameter must be 16 bytes in length or a multiple of 16 bytes.</para>

<para>Support for this method is available in the Windows XP and later operating systems.</para>
