title: Bouncycastle dependency(bcprov-ext-jdk15on-152.jar) on Itext
body: <p>I am using the bouncycastle latest jar(bcprov-ext-jdk15on-152.jar) and iText5.5.0. But I have noticed there are some interdependency between itext pdf and Bouncycastle for digital pdf sign and encryption is not working for both the version. 
  My question is
  1) If I am using the bcprov-ext-jdk15on-152.jar (latest bouncycastle jar) then is there any compatible version for itext that I can use for?
  If it is not released then when we can expect the same?
  2) As new bouncycastle jar heavily changed their API internally, is there any way to sign the pdf without Bouncycastle?</p>
  
  <p>Any suggestion will be highly appreciated..
  Thanks.</p>
