AlgorithmType enumeration

The AlgorithmType enumeration type specifies the intended purpose of a cryptographic algorithm supported by a cryptographic provider. Algorithms are typically classified by use into the following general categories:

  • Signing
  • Hashing
  • Asymmetric encryption
  • Symmetric encryption
  • Key exchange
This enumeration is used in the ICspAlgorithm interface.

Syntax


typedef enum AlgorithmType { 
  XCN_BCRYPT_UNKNOWN_INTERFACE                = 0,
  XCN_BCRYPT_SIGNATURE_INTERFACE              = 0x5,
  XCN_BCRYPT_ASYMMETRIC_ENCRYPTION_INTERFACE  = 0x3,
  XCN_BCRYPT_CIPHER_INTERFACE                 = 0x1,
  XCN_BCRYPT_HASH_INTERFACE                   = 0x2,
  XCN_BCRYPT_SECRET_AGREEMENT_INTERFACE       = 0x4,
  XCN_BCRYPT_RNG_INTERFACE                    = 0x6
} AlgorithmType;

Constants

XCN_BCRYPT_UNKNOWN_INTERFACE

The algorithm type is not defined.

XCN_BCRYPT_SIGNATURE_INTERFACE

The algorithm is used for signing. This includes the RSA algorithm, Digital Signature Algorithm (DSA), and ECDSA algorithm.

XCN_BCRYPT_ASYMMETRIC_ENCRYPTION_INTERFACE

The algorithm is used for public key encryption. This includes RSA.

XCN_BCRYPT_CIPHER_INTERFACE

The algorithm is used for symmetric encryption. This includes the RC2, RC4, Data Encryption Standard (DES), 3DED, and AES algorithms.

XCN_BCRYPT_HASH_INTERFACE

The algorithm is used for hashing. This includes the MD2, MD4, SHA1, SHA256, SHA384, SHA512 MAC, and Hash-Based Message Authentication Code (HMAC) hash algorithms.

XCN_BCRYPT_SECRET_AGREEMENT_INTERFACE

The algorithm is used for key exchange. This includes the Diffie-Hellman algorithm and ECDH algorithm.

XCN_BCRYPT_RNG_INTERFACE

The algorithm is used to generate a random number.
