Topic: Unable to validate my Digital Signature in Acrobat 6.0

Adobe Acrobat : 6.0 Professional
Platform : Windows 2000 Professional
Environment : MS Visual C++ 6.0 + AcrobatSDK 5.0
I am developing a digital Signature plug-in. I read and follow the "PDF Public-Key Digital Signature and Encryption Specification v3.2" document for (PKCS#7) dictionary standards. My plug-in is working fine with my own in Acrobat 6.0 Professional but when I try to validate it using "Default Certificate Security" handler in Acrobat 6.0 Pro it is showing a error message box "Signature is INVALID. -The document has been altered or corrupted since it was signed. - The signer's identity is valid."
Can any one help me to find what exactly the problem is??
