The resource server is also setup to encrypt a 'Description' field in the SQLite database, so it cannot be read by opening the. IDataProtector CreateProtector(string purpose); Idataprotectionprovider provides a method to generate an idataprotector interface object by passing in a purpose string (see details later). The list of purposes which contribute to the purpose chain. Provide an instance of a DataProtectionProvider initialized to the common data protection key storage location. Still, I'll provide the entire listing, above, for completeness. By voting up you can indicate which examples are most useful and appropriate. The entire purpose of a cryptographic hash function is that you can't undo it. In other words, two IDataProtector instances (created with different purpose strings) can't read each other's payloads, only their own. The ASP.NET Core data protection stack is designed to serve as the long-term replacement for the element in ASP.NET 1.x - 4.x. This method takes in a string key (known as Purpose String). Deriving a key from a parent key using the same purpose string will always give the same key material, so you can always decrypt data that was encrypted if you have the parent key and know the purpose string. We use the provider to create a protector by calling its CreateProtector () method. Purpose Strings The purpose fields must be different for the deliberate use case; two different IDataProtector instances created with two different purpose values will not be able to decipher each other's draft. Environment.Exit (-1); } // instantiate the data protection system at this folder var dataProtectionProvider = new DataProtectionProvider (new DirectoryInfo (programKeyStore), options => { // As we're using a self signed certificate we need to provide an instance of the certificate.
