DHPUBKEY structure (wincrypt.h)
The DHPUBKEY structure contains information specific to the particular Diffie-Hellman public key contained in the key BLOB.
Syntax
typedef struct _PUBKEY {
DWORD magic;
DWORD bitlen;
} DHPUBKEY, DSSPUBKEY, KEAPUBKEY, TEKPUBKEY;
Members
magic
This must always be set to DH1 (0x31484400) when used for public key BLOBs and to DH2 (0x32484400) when used for private key BLOBs.
Notice that the hexadecimal values are simply an ASCII encoding of DH1 and DH2.
bitlen
Number of bits in the prime modulus, P.
Remarks
DSSPUBKEY is an alias for this structure.
