| 12 | <p>The S end Draft web servic e allows a uthorized applicatio ns to send messages using the Direct sta ndards tha t have bee n stored a s drafts i n the past and can b e accessed by sendin g a POST r equest to /direct/se nd/draft.< /p> | |
| 13 | <h3>Auth entication </h3> | |
| 14 | <p> | |
| 15 | The API au thenticati on utilize d is based upon hash message a uthenticat ion code ( HMAC). HMA C is an au thenticati on method that combi nes a cryp tographic hash funct ion with a secret cr yptographi c key. Aft er the suc cessful re gistration of an app lication o n the API, a public and privat e key like the examp le below w ill be pro visioned f or its use . | |
| 16 | </p> | |
| 17 | <p class ="code"> | |
| 18 | Public Key : REDACTED | |
| 19 | <br/>Priva te Key: RE DACTED | |
| 20 | </p> | |
| 21 | <p> | |
| 22 | On every r equest tha t an appli cation sen ds to the API they m ust includ e an Autho rization h eader. The authoriza tion heade r is a str ing that t he API wil l utilize to confirm the ident ity, and t he message content, of the sen der. The a uthorizati on header consists o f three pa rts. The f irst part is the API identifie r, represe nted by th e word "DA AS", which stands fo r Direct a s a Servic e. The API identifie r is follo wed by a s pace that separates it from th e identify ing conten t. The ide ntifying c ontent con sists of t he unique public key and the b ase64 enco ded HMAC h ash genera ted by the request c ontent and the priva te key, de limited by a colon. An example of the au thorizatio n header i s below. | |
| 23 | </p> | |
| 24 | <p class ="code"> | |
| 25 | Authorizat ion: DAAS REDACTED | |
| 26 | </p> | |
| 27 | <p> | |
| 28 | The HMAC s tring is g enerated b y running an HMAC ha sh functio n on a pla in text st ring and t he applica tion's pri vate key. The plain text strin g that mus t be hashe d using HM AC is cons tructed as follows: | |
| 29 | <ul> | |
| 30 | <l i>HTTP Req uest Type< /li> | |
| 31 | <l i>Date</li > | |
| 32 | <l i>Content- MD5 (Optio nal)</li> | |
| 33 | <l i>Content Type (Not including boundary)< /li> | |
| 34 | <l i>URI</li> | |
| 35 | </ul> | |
| 36 | These valu es are sep arated by new line c haracters ("\n"). An example o f the plai n text str ing is bel ow: | |
| 37 | </p> | |
| 38 | <p class ="code"> | |

| 50 | In the exa mple above the Conte nt MD5 is provided b ut this is an option al field. If the Con tent MD5 h eader is n ot specifi ed then th e hash sho uld not ha ve the MD5 specified either. | |
| 51 | </p> | |
| 52 | <h3>Head ers</h3> | |
| 53 | <p> | |
| 54 | There are three head ers that m ust be sen t with eac h send dra ft call an d one opti onal heade r. These h eaders are used in v alidating who the me ssage came from, who it is goi ng to and the messag e itself. | |

| 58 | <u l> | |
| 59 | <li> Authorizat ion</li> | |
| 60 | <p> | |
| 61 | The fi rst requir ed header is the Aut horization header co vered in t he Authent ication se ction at t he top of this page. | |
| 62 | </p> | |
| 63 | <li> Date or X- Daas-Date< /li> | |
| 64 | <p> | |
| 65 | The se cond requi red header that must be includ ed is the Date heade r. Some br owsers wil l not let an applica tion speci fy the Dat e header p rogrammati cally, so in this ca se it is a lso accept able to us e the X-Da as-Date he ader as th e API will interpret them inte rchangeabl y. This he ader shoul d be popul ated with the curren t date and time, in any standa rd format (including time zone informati on if not time zone agnostic), when the POST reque st is subm itted. The value sup plied in t he Date he ader must match the value used in the cr eation of the hash s tring for the Author ization he ader. | |

| 73 | The fi nal requir ed header for POST r equests is the Conte nt-Type. T he Content -Type head er must ma tch the Co ntent-Type provided in the has h string f or the Aut horization header ex cept the h ash string does not include th e boundary parameter of the Co ntent-Type if there is one (i. e. applica tion/x-www -form-urle ncoded Con tent-Type) . | |
| 74 | </p> | |
| 75 | <li> Content-Md 5</li> | |
| 76 | <p> | |
| 77 | The op tional hea der is the Content-M d5 header. This head er should contain an MD5 hash of the ent ire POST b ody. If th is header is specifi ed then it must also be includ ed in the hash strin g for the Authorizat ion header . When pro vided, thi s serves a s an extra security precaution above and beyond TL S to ensur e the POST request s ent has no t been mod ified in t ransit. | |
