22  * RMCP+ Authenticated Key-Exchange Protocol (RAKP)
24  * RAKP-None is not supported as per the following recommendation

65      * @brief Generate the Hash Message Authentication Code
67      * This API is invoked to generate the Key Exchange Authentication Code
69      * Integrity Key.
75      * @note The user key which is the secret key for the hash operation
91      * @note The session integrity key which is the secret key for the
100      * @param[in] algo - authentication algorithm
117     // User Key is hardcoded to PASSW0RD till the IPMI User account
127     // Session Integrity Key
152  * RAKP-HMAC-SHA1 specifies the use of RAKP messages for the key exchange
153  * portion of establishing the session, and that HMAC-SHA1 (per [RFC2104]) is
154  * used to create 20-byte Key Exchange Authentication Code fields in RAKP
155  * Message 2 and RAKP Message 3. HMAC-SHA1-96(per [RFC2404]) is used for
156  * generating a 12-byte Integrity Check Value field for RAKP Message 4.
186  * RAKP-HMAC-SHA256 specifies the use of RAKP messages for the key exchange
187  * portion of establishing the session, and that HMAC-SHA256 (per [FIPS 180-2]
188  * and [RFC4634] and is used to create a 32-byte Key Exchange Authentication
189  * Code fields in RAKP Message 2 and RAKP Message 3. HMAC-SHA256-128 (per
190  * [RFC4868]) is used for generating a 16-byte Integrity Check Value field for
