I have a Problem verifying an Email Signature with BC. Both, Thunderbird and Outlook said that this Email is valid, but BC doesn't.
I am using the SignedMailValidator class.
The Error that occours is :
org.bouncycastle.cms.CM****ception: invalid signature format in message: content hash found in signed attributes different
.....
Caused by: java.security.SignatureException: content hash found in signed attributes different
The Email Content :
MIME-Version: 1.0

micalg=sha1;
