MD5_HMAC

The MD5_HMAC function performs the MD5 HMAC translate.

unsigned char* __stdcall
MD5_HMAC(
    unsigned char* pucText,       // [in]
    unsigned long ulText_Len,     // [in]
    unsigned char* pucKey,        // [in]
    unsigned long ulKey_Len,      // [in]
    unsigned char* pucKey1,       // [in]
    unsigned char* pucKey2,       // [in]
    unsigned char* pucDigest      // [out]
);

Parameters

pucText

[in] Points to the input data stream, and not exceed 55 bytes.

ulText_Len

[in] Size of the input data stream, and not exceed 55 bytes.

pucKey

[in] Points to the secret.

ulKey_Len

[in] size of type secret.

pucKey1

[in] NULL or pointer to an array of 16 bytes that receives MD5 (SECRET XOR iPad).

iPad = the byte 0x36 repeated 64 times.

pucKey2

[in] NULL or a pointer to an array of 16 bytes that receives MD5(SECRET XOR oPad).

oPad = the byte 0x5C repeated 64 times.

pucDigest

[out] Pointer to a 16-byte buffer that receives the message digest.

Remark

HMAC-MD5 algorithm is defined in RFC-2085, you may found this document on http://www.rfc-editor.org/rfc/rfc2085.txt.

Return Values

This function returns a pointer to the digest buffer.
