Hello everyone,

currently I use the latest version of iText I can sign a pdf with the sha256
parcontre moùent verification is done with the code of iText fails!

Here is the exception thrown:

ExceptionConverter: java.security.InvalidKeyException: Illegal Key must not
be null

Has com.itextpdf.text.pdf.AcroFields.verifySignature (AcroFields.java: 2258)
Has myPackage.DocumentPDFSigne.verifierPDF (DocumentPDFSigne.java: 317)
  

On reading this error stack we can see that the signing certificate does not
contain the public key but this is not the case because my signing
certificate contain the key public good.

Is there someone who can tell me more about? 

Maybe you too have already experience this problem.

Thank you for your help.
