Extra data detected in stream

[rsouthpaw]

I am trying to implement late external signing. I am using (Javascript) digitalBazaar forgejs for creating SignedData using PKCS12. I just want to insert that SignedData in Bouncy Castle and finally inject that into pdf using pdfbox.

When trying this

ASN1Sequence.getInstance(signedDataByteArray)

I get Extra data detected in stream. How do I correct this? What Am i missing?

it looks like there is garbage at the end of the stream - I'd suggest checking it first. If it's safe to do so you can create an ASN1InputStream on it and just do a readObject().

Have you find a solution?
