DataProtector.ProviderUnprotect Method
.NET Framework 4.5
Specifies the delegate method in the derived class that the Unprotect method in the base class calls back into.
Namespace: System.Security.Cryptography
Assembly: System.Security (in System.Security.dll)
Parameters
- encryptedData
- Type: System.Byte[]
The data to be unencrypted.
The following example shows an implementation of the ProviderUnProtect method. It is part of a larger code example for the DataProtector class.
// To allow a service to hand out instances of a DataProtector we demand unrestricted DataProtectionPermission // in the constructor, but Assert the permission when ProviderUnprotect is called.. This is similar to FileStream // where access is checked at time of creation, not time of use. [SecuritySafeCritical] [DataProtectionPermission(SecurityAction.Assert, UnprotectData = true)] protected override byte[] ProviderUnprotect(byte[] encryptedData) { ProtectedMemory.Unprotect(encryptedData,Scope); return encryptedData; }
