BCryptEnumAlgorithms function

-description

The BCryptEnumAlgorithms function gets a list of the registered algorithm identifiers.

-parameters

-param dwAlgOperations [in]

A value that specifies the algorithm operation types to include in the enumeration. This can be a combination of one or more of the following values.

Value	Meaning
BCRYPT_CIPHER_OPERATION 0x00000001	Include the cipher algorithms in the enumeration.
BCRYPT_HASH_OPERATION 0x00000002	Include the hash algorithms in the enumeration.
BCRYPT_ASYMMETRIC_ENCRYPTION_OPERATION 0x00000004	Include the asymmetric encryption algorithms in the enumeration.
BCRYPT_SECRET_AGREEMENT_OPERATION 0x00000008	Include the secret agreement algorithms in the enumeration.
BCRYPT_SIGNATURE_OPERATION 0x00000010	Include the signature algorithms in the enumeration.
BCRYPT_RNG_OPERATION 0x00000020	Include the random number generator (RNG) algorithms in the enumeration.

-param pAlgCount [out]

A pointer to a ULONG variable to receive the number of elements in the ppAlgList array.

-param ppAlgList [out]

The address of a BCRYPT_ALGORITHM_IDENTIFIER structure pointer to receive the array of registered algorithm identifiers. This pointer must be passed to the BCryptFreeBuffer function when it is no longer needed.

-param dwFlags [in]

A set of flags that modify the behavior of this function. No flags are defined for this function.

-returns

Returns a status code that indicates the success or failure of the function.

Possible return codes include, but are not limited to, the following.

Return code	Description
STATUS_SUCCESS	The function was successful.
STATUS_INVALID_PARAMETER	One or more parameters are not valid.
STATUS_NO_MEMORY	A memory allocation failure occurred.

-remarks

BCryptEnumAlgorithms can be called either from user mode or kernel mode. Kernel mode callers must be executing at PASSIVE_LEVEL IRQL.
