EnumAlgs Sample: Enumerate Algorithms

Click to open or copy the files for the EnumAlgs sample.

The EnumAlgs sample is a console application that lists the algorithms supported by the default PROV_RSA_FULL provider. By default, this will be the Microsoft RSA Base Provider, which is included along with the operating system.

Note   Run the Inituser sample (or equivalent) prior to running this sample in order to create a key container for the default user.

In addition to listing the name of each supported algorithm, this sample also lists the following.

• The type of algorithm (encryption, hash, key exchange, or signature).
  
  
• The key length used by the algorithm (or number of bits in the hash value for hash algorithms).
  
  
• The algorithm identifier for the algorithm. This value can be passed to the appropriate CryptoAPI function in order to create a key or hash object that makes use of the particular algorithm.

The core structure of this sample can be used by applications that want to display a list of available applications to the user.
