Digital signature error

Hi All,

I was able to post a digitally signed message with SOAP UI 3.6.1,
but Same message I couldn't able to post with SOAP UI 5.0
Following is the error getting from server with SOAP UI 5.0.
<faultcode>wsse:FailedCheck</faultcode>
<faultstring>The signature or decryption was invalid</faultstring>
<detail>error:04091068:rsa routines:INT_RSA_VERIFY:bad signature</detail>
Does any one have experienced this kind of issue before or any idea why this error is coming in 5.0. Help is greatly appriciated.

Thanks
Kumar.
