Creating a signature and Encrypt the file

[Former Member]

Hi Experts,

I have an requirement, I need to create a module in which I need to pass four values (Namely signing key, signing algorithm, encyption key and encryption algorithm) through parameters as inputs. Based on these parameters, I need to create the signature for the input xml file and I have to encrypted the file. Please Guide me. Give some useful links, documents or codes to how to do this. Help me in this regard.

Thanks in Advance,

Hi,

Digitally signing of messages is possible by using cryptographic toolkits.

All required java programs are imported as archives into XI. Java mapping is written utilizing the imported java archives which actually performs the digital signature creation for the outgoing messages from XI and digital signature verification for the incoming messages to XI.

You may also use the SAP cryptographic toolkit available from SAP market place for signing encrypting. See i.e. http://help.sap.com/saphelp_nw04/helpdata/en/4f/65c3b32107964996a56e4165077e24/frameset.htm

which type of signature do you need to generate?

XML? PKCS7?? SMIME??

What is the requiremenet on the encryption??? Pls elaborate.

These all features are available with SAP SSF APIs for Java. search your NWDS installation for keystore_api.jar & tc_sec_ssf.jar before you try to use it in your programs, you can refer to the below link for sample code.

Hi Amol,

I need to generate the signature based on SMIME type. My requirement is, I need to sign a document (based on Signing algorithm ) and encrypt (based on the Encryption Algorithm) that file. I'll pass this signing and encryption algorithm as parameters to the module for signing and encryption for that document.

Please tell me where I can get this keystore_api.jar file.

I have already gone through this [SAP Help|http://help.sap.com/saphelp_nw04/helpdata/en/a4/d0201854fb6a4cb9545892b49d4851/content.htm], there is no indication where they are mentioning signing and encryption algorithm. Please help me in this regard.

Thanks in Advance,

Hi Venkatesh,

Did the get the two file keystore_api.jar & tc_sec_ssf.jar. Can you point me to the Installtion file level where they are present.

Hi,

You can get this two jar files from your XI server in the following locations:

\usr\sap\<SID>\DVEBMGS10\j2ee\cluster\dispatcher\bin\interfaces\keystore_api

\usr\sap\<SID>\DVEBMGS10\j2ee\cluster\server0\bin\ext\security.class
