Chinh Nguyen commented on TIKA-2857:
------------------------------------

I don't know if it's a Tika issue or a Bouncy Castle issue, so I have raised a separate item with bouncy castle: https://github.com/bcgit/bc-java/issues/499

> I cannot get tika to parse any PKCS7 files. All seem to generate Java exceptions:
> * Create a "cert-only" file: {{openssl crl2pkcs7 -nocrl -certfile /usr/share/ca-certificates/mozilla/Entrust_Root_Certification_Authority.crt -out cert.p7 -outform der}}
> * Create a signed file: {{echo "hello world" | openssl cms -sign -inkey key.pem -signer cert.pem -md sha256 -outform der -nodetach -out sign.p7}}
> * Create a digest file: {{echo "hello world" | openssl cms -digest_create -md sha256 -outform der -out digest.p7}}
> Try to parse these files:
