.net - Change Microsoft Config File Encryption Method From TripleDES -

-

when encrypting ("protecting") microsoft config sections, looks xml below. follows (at least partially) w3 spec xml encryption.

however, in xml below you'll see encryptionmethod under encrypteddata section "tripledes-cbc". able change more-secure alternative, aes, specified in aforementioned w3 spec well.

in many calls microsoft's support engineers, near understanding question, less answering it. there way change encryption method?

i forgot mention earlier set rsaprotectedconfigurationprovider, key appears encrypted rsa, whereas data encrypted 3des.

<misccryptodata configprotectionprovider="someconfigprotectionprovider">   <encrypteddata type="http://www.w3.org/2001/04/xmlenc#element" xmlns="http://www.w3.org/2001/04/xmlenc#">     <encryptionmethod algorithm="http://www.w3.org/2001/04/xmlenc#tripledes-cbc"/>     <keyinfo xmlns="http://www.w3.org/2000/09/xmldsig#">       <encryptedkey xmlns="http://www.w3.org/2001/04/xmlenc#">         <encryptionmethod algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5"/>         <keyinfo xmlns="http://www.w3.org/2000/09/xmldsig#">           <keyname>rsa key</keyname>         </keyinfo>         <cipherdata>           <ciphervalue>asf78ag78asg\...cryptoyadayada...asdf8r=</ciphervalue>         </cipherdata>       </encryptedkey>     </keyinfo>     <cipherdata>       <ciphervalue>zxcv6asdf35...largercryptoyadayada...u7i8o9p=</ciphervalue>     </cipherdata>   </encrypteddata> </misccryptodata>

i've checked rsaprotectedconfigurationprovider reflector , found out there nothing can change tripledes-cbc else.

so have write own protectedconfigurationprovider if want use aes encryption. may want use reflector give start.

java - SNMP4J General Variable Binding Error -

-
i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

Determine if a XmlNode is empty or null in C#? -

-
the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
