signature

问题 All, I am testing some java code that validates an XML digital signature. I am using the standard JSR 105 API in the JDK. I am using an Exclusive Canonicalization method and an Enveloped signature. The incoming XML message looks something like this: <doc xmlns:a="urn:abc.my.domain.com"> <a:x>12345</a:x> </doc> This message goes through a complex system with various XML parsers (CXF, JAXB, XSLT, etc.) and somehow gets changed to this: <doc xmlns:b="urn:abc.my.domain.com"> <b:x>12345</b:x> <

问题 Ok, so I can use dumpbin.exe /exports library.dll to find all methods in the dll. ...but how do I find out which arguments to pass into them? Without a header file of course. 回答1: For the usual C-style exports (e.g., Windows API DLLs): You can't. This information is not stored in the DLL and is inevitably lost after compilation (unless you have the headers or debuging symbols). C++ exports, on the other hand, store their signature as part of the mangled function name and you can view them

问题 I m working on one project about certificates and digital signatures in Java, but i cant understand following situation. Certificates of sender and receiver of document was valid when signature is created. But in time, when receiver received document, certificate of sender had expired. Is that valid situation, so receiver can normally verify signature, or he cant? One more question. For what is used Non-repudiation key usage? 回答1: A digital signature will remain cryptographically correct even

问题 This is what I want to do: Generate a 512 bit RSA keypair in Java/Android Generate a SHA1withRSA signature for some message in Java Send message, signature and public key to PHP (for testing this will be done at the same time) Verify the message in PHP using phpseclib What I got so far: On the Java side: String msg = "Test message"; // generate keypair KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); keyGen.initialize(512); KeyPair keyPair = keyGen.generateKeyPair(); // generate

问题 Have found a function address in a DLL. Have no source code for this DLL, not mine. This DLL is not really changed frequently, but when changed, it is a problem for me to find it by disassembling. Saw some notes in web about making it signature and then find it by this saved signature. Can you, please, give some ideas or working example on how to implement this? 回答1: You can achieve this by code signature scanning, which is something I have done in the past. The concept mainly works by

问题 I created this simple email signature. I SELECT ALL and COPY PASTE in signature part... Its working fine in outlook but in MAC Mail (Version 7.3)... Image goes out of TABLE www.cellsouq.com/xtra/emailsign/email.html Can anyone help me in this. I want to keep logo infront of name/designation (on right side) regards 回答1: Not all mail clients understand colspan="2". Use 2 tables and it will be fine. 来源： https://stackoverflow.com/questions/24612830/email-signature-alignment-issue-at-mac
