CRYPT_MASK_GEN_ALGORITHM structure (wincrypt.h)

  • Article

The CRYPT_MASK_GEN_ALGORITHM structure identifies the algorithm used to generate an RSA PKCS #1 v2.1 signature mask.

Syntax

typedef struct _CRYPT_MASK_GEN_ALGORITHM {
  LPSTR                      pszObjId;
  CRYPT_ALGORITHM_IDENTIFIER HashAlgorithm;
} CRYPT_MASK_GEN_ALGORITHM, *PCRYPT_MASK_GEN_ALGORITHM;

Members

pszObjId

The address of a null-terminated ANSI string that contains the object identifier (OID) of the mask generation algorithm. This can be the following value or any other mask generation function OID.

Value Meaning
szOID_RSA_MGF1
"1.2.840.113549.1.1.8"
 The RSA MGF1 function.

HashAlgorithm

A CRYPT_ALGORITHM_IDENTIFIER structure that identifies the hash algorithm to use for the mask generation.
