To be able to experiment with the code samples in this and following chapters, you need a personal certificate of your own. The conditions under which the CryptoAPI displays warning messages include, but are not limited to, the following: Therefore, when using AspEncrypt in an ASP/ASP.NET environment to perform private key-related operations such as generating signed mail messages, you should move the personal certificates you want to use from the HKEY_CURRENT_USER to HKEY_LOCAL_MACHINE section of the registry.
The time saving that I made by doing the entire unit test in NUnit was well worth the effort, I never would have had this much code coverage without using it. From The principal is encoded as a protection descriptor rule. After executing, the encryption object is now ready for use.
Licensing, Signing and Encryption [Answered] RSS
If the customer has no network connectivity, there’s no way to revoke their software license early. The real licensing functionality resides in the license provider class, which is described later. For the 64-bit block cipher, I recommend , which should be fast and simple enough to implement. When the previous code is executed, a new key and IV are generated and placed in the Key and IV properties, respectively.

To decrypt encrypted configuration file contents, you use the Aspnet_regiis.Exe tool with the -pd switch and the name of the configuration element to be decrypted. Without theÂpri switch, you would only be able to encrypt data with the exported key. If you want to encrypt something for a user, you should go into his certificate store, and pull out his encryption certificate. To change the implementation for all future keys, set the AuthenticatedEncryptorConfiguration property in KeyManagementOptions.
Machine Key Container
In addition to the Subject and Issuer properties covered above, the CryptoCert object also offers properties corresponding to the certificate property dialog shown above, and several others unrelated to that dialog. This article assumes familiarity with MicrosoftÂ® ASP.NET programming and ASP.NET server control authoring. The actual license is XML but we need to encrypt it and then in our program decrypt it. A message encrypted with the public key can only be decrypted with the corresponding private key, and vice versa.
Encryption Examples for Classic ASP
For information on referencing a section of a Web.Config file, see the class. This article builds on that architecture to provide a licensing implementation that is optimized specifically for ASP.NET controls and that you can extend to create custom licensing schemes, such as: An ASP.NET server control licensing scheme must satisfy the following requirements: For simplicity, we have used the term server control in the preceding list. This is an early working version using AES256, I plan to add additional algorithm support in the future. Note that DES (FIPS 46-3) was withdrawn in May 2005, and is no longer approved for Federal use. But you shouldn’t need to know that, if you are using a standard implementation of a well-vetted crypto algorithm.) One approach to revocation is to have your client software contact a central server for periodic download of the revocation list.
