containing class for an CMS AuthEnveloped Data object

  • Constructor Details

    • CMSAuthEnvelopedData

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

    • CMSAuthEnvelopedData

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

    • CMSAuthEnvelopedData

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