第三十三章使用派生密钥令牌进行加密和签名 - 使用 <DerivedKeyToken>

第三十三章使用派生密钥令牌进行加密和签名 - 使用

进行加密（一）

如果加密了任何安全标头元素，请将它们添加到 WS-Security 标头元素中。为此，请调用 Web 客户端或 Web 服务的 SecurityOut 属性的 AddSecurityElement() 方法。在这种情况下，需要两个参数：

a. 安全标头元素（而不是从中生成的的 %XML.Security.EncryptedData）。

b. 引用列表实例。第二个参数指定将第一个参数指定的项目放在何处。如果参数是 A、B，则 IRIS 确保 A 在 B 之后。指定此项以便收件人首先处理引用列表，然后再处理依赖于它的加密安全标头元素。

 do client.SecurityOut.AddSecurityElement(userToken,reflist)

如果仅加密了 SOAP 主体，系统会自动将 <EncryptedData> 元素作为 <Body>的子元素。

发送 SOAP 消息。请参阅添加安全标头元素中的一般注释。

例如，以下客户端代码对 SOAP 主体和 <UsernameToken>进行加密：

  // Create UsernameTokenset userToken=##class(%SOAP.Security.UsernameToken).Create("_SYSTEM","SYS")// get credentials for encryptionset cred = ##class(%SYS.X509Credentials).GetByAlias("servercred") // get EncryptedKey element to encrypt <UsernameToken)// $$$SOAPWSEncryptNone means that this key does not encrypt the bodyset enckey=##class(%XML.Security.EncryptedKey).CreateX509(cred,$$$SOAPWSEncryptNone)//add to WS-Security Headerdo client.SecurityOut.AddSecurityElement(enckey)// get derived key to use for encryption// second argument specifies how the derived key // refers to the key on which it is basedset dkenc=##class(%SOAP.WSSC.DerivedKeyToken).Create(enckey,$$$SOAPWSReferenceEncryptedKey)//add to WS-Security Headerdo client.SecurityOut.AddSecurityElement(dkenc)// create <EncryptedData> element to contain <UserToken>set encdata=##class(%XML.Security.EncryptedData).Create(dkenc,userToken,$$$SOAPWSReferenceDerivedKey)// create <EncryptedData> element to contain SOAP bodyset encdata2=##class(%XML.Security.EncryptedData).Create(dkenc,"",$$$SOAPWSReferenceDerivedKey)// create <ReferenceList> with <DataReference> elements that// point to these two <EncryptedData> elementsset reflist=##class(%XML.Security.ReferenceList).%New()set dataref=##class(%XML.Security.DataReference).Create(encdata)do reflist.AddReference(dataref)set dataref2=##class(%XML.Security.DataReference).Create(encdata2)do reflist.AddReference(dataref2)// add <ReferenceList> to WS-Security headerdo client.SecurityOut.AddSecurityElement(reflist)// add encrypted <UserName> to security header;// 2nd argument specifies positiondo client.SecurityOut.AddSecurityElement(userToken,reflist)// encrypted SOAP body is handled automatically

客户端发送如下消息：

再举一个例子，以下 Web 服务在入站消息中接收 <EncryptedKey> ，并使用它来生成 <DerivedKeyToken> ，用于加密响应的各个部分：

  // create <DerivedKeyToken> based on first <EncryptedKey> in inbound message;// refer to it with SHA1 thumbprintset refopt=$$$SOAPWSReferenceEncryptedKeySHA1set dkenc=##class(%SOAP.WSSC.DerivedKeyToken).Create(,refopt)do ..SecurityOut.AddSecurityElement(dkenc)// create <EncryptedData> element to contain SOAP bodyset encdata=##class(%XML.Security.EncryptedData).Create(dkenc,"",$$$SOAPWSReferenceDerivedKey)// create <ReferenceList> with <DataReference> elements that// point to the <EncryptedData> elementsset reflist=##class(%XML.Security.ReferenceList).%New()set dataref=##class(%XML.Security.DataReference).Create(encdata)do reflist.AddReference(dataref)// add <ReferenceList> to WS-Security headerdo ..SecurityOut.AddSecurityElement(reflist)

该 Web 服务发送如下消息：
