So, for statically linked OpenSSL, you can have the developer use a different TLS library, or implement their own callback function with logging, or you dig out the debugger to extract it yourself. It also describes the state of more implementations of SSL key logging, notably OpenSSL and deriviaves let applications call SSLCTXsetkeylogcallback() while NSS and GnuTLS have the SSLKEYLOGFILE environment variable. With a reminder that TLS 1.3 will be all PFS. It calls out that ECDHE cannot be decrypted with just the RSA private key. Then point Wireshark at it: Edit > Preferences, Protocols > SSL > (Pre)-Master-Secret log filename.Įdit: another reference for TLS decryption is SSL/TLS decrption presentation from SharkFest ASIA 2018. This is supported by a few clients, notably browsers, NSS, and libcurl. Set environment variable SSLKEYLOGFILE to a file for the trace. Instead, use session key logging on a client, or server. Do not change the protocol (or use OpenSSL that old), that alters the security. I am using: $ openssl version OpenSSL 0.9.8zh ĭon't. The output is as follows: SS元 alert read:fatal:handshake failure SSL_connect:failed in SSLv3 However when I do this: openssl s_client -connect :443 -debug -msg -state -cipher AES128-SHA -ssl3 When I do this: openssl s_client -connect server:443 -debug -msg -state -cipher AES128-SHA In order to decrypt the transaction, I need to force the client/server to disable PFC (perfect forward secrecy). So for date fields, type String should just be accepted.I am trying to get a wireshark trace that I can decrypt for a request between a client and an ALB. In my opinion, the validation should be changed because there is as far as I know no excel Date-format available for dd.mm.jjjj. I found no SAP notes or other questions or blogs about this problem.Ĭurrently we change the XML-file: for every date field we change type String to Date. I have already reported this as an incident at SAP but I'm curious if we are the first to encounter this problem. There is no Date (Datum) format of type dd.mm.yyyy in Excel. ![]() The reason it is a type String and not Date is because in Excel, the following cell format is being used.Īpperently, this is translated by Excel-XML to type String. We found that during the upload a Validation is performed in method:ĬL_DMC_MD_EXTRACTOR_EXCEL_XML=>VALIDATE_PAYLOAD_DATA_TYPE at location 159-160Īt runtime, value for LV_TYPE is String, not Date. If we look at the XML-file in an XML-editor, we see that the date fields have a type String and not Date. ![]() ![]() The Dutch date format is the same as the German format. When populating the XML in Excel we use the date-format dd.mm.yyyy as described in the Introduction Sheet of the Template. ![]() We follow the normal steps: download XML-template, populate using Excel (XML 2003 Excel format), save and then upload in the DMC Fiori App. For every date-type fields we get two error messages:ĬNV_DMC_MD_EXTRACTOR 033 Field "Datum: berekening geldig tot" from sheet "Rekenwaarden" has a wrong data type in line 9ĬNV_DMC_MD_EXTRACTOR 034 Data type Date is expected in field "Datum: berekening geldig vanaf" The issue is that during upload of any DMC-file with date-type fields, we get the same error messages for every date-type field like 'POSTING_DATE', 'VALID_FROM, VALID_TO etc. We are using the Files/Staging Table scenario. Now we started testing SAP standard and custom migration objects and we are running into problems with the Date format for all migration objects. We are using the DMC and have copied our own migration objects to a new migration project. We are busy with an upgrade from S/4HANA 1809 to 2021.
