  • Article

The CERT_DSS_PARAMETERS structure contains parameters associated with a Digital Signature Standard (DSS) public key algorithm.

Syntax

typedef struct _CERT_DSS_PARAMETERS {
  CRYPT_UINT_BLOB p;
  CRYPT_UINT_BLOB q;
  CRYPT_UINT_BLOB g;
} CERT_DSS_PARAMETERS, *PCERT_DSS_PARAMETERS;

Members

p

Prime modulus P. The most significant bit of the most significant byte must always be set to 1.

q

Prime Q. It is 20 bytes in length. The most significant bit of the most significant byte must be set to 1.

g

Generator G. Must be the same length as p (must be padded with 0x00 bytes if it is less).
