    • Method Detail

      • getKeyEncryptionAlgorithm

        public org.bouncycastle.asn1.x509.AlgorithmIdentifier getKeyEncryptionAlgorithm()
        Return the key encryption algorithm details for the key in this recipient.
        Returns:
        AlgorithmIdentifier representing the key encryption algorithm.
      • getKeyEncryptionAlgOID

        public String getKeyEncryptionAlgOID()
        return the object identifier for the key encryption algorithm.
        Returns:
        OID for key encryption algorithm.
      • getKeyEncryptionAlgParams

        public byte[] getKeyEncryptionAlgParams()
        return the ASN.1 encoded key encryption algorithm parameters, or null if there aren't any.
        Returns:
        ASN.1 encoding of key encryption algorithm parameters.
      • getContentDigest

        public byte[] getContentDigest()
        Return the content digest calculated during the read of the content if one has been generated. This will only happen if we are dealing with authenticated data and authenticated attributes are present.
        Returns:
        byte array containing the digest.
      • getMac

        public byte[] getMac()
        Return the MAC calculated for the recipient. Note: this call is only meaningful once all the content has been read.
        Returns:
        byte array containing the mac.
      • getContent

        public byte[] getContent​(Recipient recipient)
                          throws CMSException
        Return the decrypted/encapsulated content in the EnvelopedData after recovering the content encryption/MAC key using the passed in Recipient.
        Parameters:
        recipient - recipient object to use to recover content encryption key
        Returns:
        the content inside the EnvelopedData this RecipientInformation is associated with.
        Throws:
        CMSException - if the content-encryption/MAC key cannot be recovered.
      • getContentType

        public org.bouncycastle.asn1.ASN1ObjectIdentifier getContentType()
        Return the content type of the encapsulated data accessed by this recipient.
        Returns:
        the content type OID.
      • getContentStream

        public CMSTypedStream getContentStream​(Recipient recipient)
                                        throws CMSException,
                                               IOException
        Return a CMSTypedStream representing the content in the EnvelopedData after recovering the content encryption/MAC key using the passed in Recipient.
        Parameters:
        recipient - recipient object to use to recover content encryption key
        Returns:
        the content inside the EnvelopedData this RecipientInformation is associated with.
        Throws:
        CMSException - if the content-encryption/MAC key cannot be recovered.
        IOException
