This structure specifies the hash algorithm and the inner and outer strings that are to be used to calculate the HMAC hash.
Syntax
typedef struct _HMAC_Info {
ALG_ID HashAlgid;
BYTE* pbInnerString;
DWORD cbInnerString;
BYTE* pbOuterString;
DWORD cbOuterString;
} HMAC_INFO, *PHMAC_INFO;
Members
- HashAlgid
Hash algorithm to be used.
- pbInnerString
Must be NULL. The default inner string is defined as the byte 0x36 repeated 64 times.
- cbInnerString
Must be zero. The CSP uses the default inner string.
- pbOuterString
Must be NULL. The default outer string is defined as the byte 0x5C repeated 64 times.
- cbOuterString
Must be zero. The CSP uses the default outer string.
