  • Constructor Details

    • CMSDigestedData

      public CMSDigestedData(byte[] compressedData) throws CMSException
      Create a CMSDigestedData object from its encoding.
      Parameters:
      compressedData - the complete encoding of the DigestedData structure (a CMS ContentInfo). The array must hold the entire encoding and nothing extra - trailing bytes beyond the DigestedData are not permitted.
      Throws:
      CMSException - if the encoding cannot be parsed as a DigestedData.

    • CMSDigestedData

      public CMSDigestedData(InputStream compressedData) throws CMSException
      Create a CMSDigestedData object from a stream.
      Parameters:
      compressedData - a stream positioned at the start of the DigestedData encoding (a CMS ContentInfo).
      Throws:
      CMSException - if the encoding cannot be parsed as a DigestedData.

    • CMSDigestedData

      public CMSDigestedData(org.bouncycastle.asn1.cms.ContentInfo contentInfo) throws CMSException
      Create a CMSDigestedData object from an already-parsed ContentInfo.
      Parameters:
      contentInfo - the ContentInfo carrying the DigestedData.
      Throws:
      CMSException - if the ContentInfo does not hold a well-formed DigestedData.
