More about Difference between verify a message file and message string

[Jessica Wei]

Hi, all   I trace the source code, it seems after comparing, the correct result is set to m_verified variable in VerifierFilter for both case. But when I use GetLastResult() to read this variable, the memory of variable is corrupt when using StringSource.   Does someone know what cause it?   Jessica      ----- Original Message ----- From: Jessica Wei To: [EMAIL PROTECTED] Sent: Thursday, January 15, 2004 11:07 AM Subject: Difference between verify a message file and message string Hi, all   I tried to verify a signature that the plain text is just a simple string "test data". When I put the data into a file called "message.txt", then using following code to verify the signature:   ... VerifierFilter* verifierFilter = new VerifierFilter(pubVerifier);  verifierFilter->Put(sign, pubVerifier.SignatureLength());  FileSource f("message.txt", true, verifierFilter); bool retval = verifierFilter->GetLastResult();   It gave me correct answer.   However, when I read the plain data from a string, for example, ...  VerifierFilter* verifierFilter = new VerifierFilter(pubVerifier);  verifierFilter->Put(sign, pubVerifier.SignatureLength()); StringSource ("test data", true, verifierFilter);  return verifierFilter->GetLastResult();   It gave me incorrect answer.   I want to use second proach to verify a signature. Could somebody know what's the problem?   Thanks for help.   Jessica
