AlgorithmType enumeration

-description

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.

-enum-fields

-field XCN_BCRYPT_UNKNOWN_INTERFACE:0

The algorithm type is not defined.

-field XCN_BCRYPT_CIPHER_INTERFACE:0x1

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

-field XCN_BCRYPT_HASH_INTERFACE:0x2

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.

-field XCN_BCRYPT_ASYMMETRIC_ENCRYPTION_INTERFACE:0x3

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

-field XCN_BCRYPT_SIGNATURE_INTERFACE:0x5

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

-field XCN_BCRYPT_SECRET_AGREEMENT_INTERFACE:0x4

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

-field XCN_BCRYPT_RNG_INTERFACE:0x6

The algorithm is used to generate a random number.

-field XCN_BCRYPT_KEY_DERIVATION_INTERFACE:0x7
