SecPkgContext_KeyInfo

The SecPkgContext_KeyInfo structure contains information about the keys used in a security context. It does not return actual key values, but rather information about keys. The QueryContextAttributes function uses this structure.

typedef struct _SecPkgContext_KeyInfo {
    SEC_CHAR   * sSignatureAlgorithmName;
    SEC_CHAR   * sEncryptAlgorithmName;
    ULONG        KeySize;
    ULONG        SignatureAlgorithm;
    ULONG        EncryptAlgorithm;
} SecPkgContext_KeyInfo, * PSecPkgContext_KeyInfo;

Members

sSignatureAlgorithmName

Pointer to a NULL-terminated string containing the name, if available, of the algorithm used for generating signatures. MD5 and SHA-2 are typical algorithm names that might be returned.

sEncryptAlgorithmName

Pointer to a NULL-terminated string containing the name, if available, of the algorithm used for encrypting messages. Reserved for future use.

KeySize

Specifies the size, in bits, of the key used for encrypting messages. Reserved for future use.

SignatureAlgorithm

Specifies the CryptoAPI algorithm identifier (ALG_ID) in use for the signature, if available.

EncryptAlgorithm

Specifies the CryptoAPI algorithm identifier (ALG_ID) in use for encrypting messages. Reserved for future use.
