public abstract class AbstractRecipient extends Object
Base class for the CMS recipient implementations, carrying the optional restrictions on which content-encryption algorithms a recipient is willing to recover content for, and on the minimum AEAD authentication tag size it will accept.

  • Method Details

    • setAllowedContentAlgorithmSet

      protected final void setAllowedContentAlgorithmSet(Set<org.bouncycastle.asn1.ASN1ObjectIdentifier> allowedContentAlgorithms)

    • isContentAlgorithmAllowed

      protected final boolean isContentAlgorithmAllowed(org.bouncycastle.asn1.ASN1ObjectIdentifier contentAlgorithm)

    • setMinimumTagSizeInBits

      protected final void setMinimumTagSizeInBits(int tagSizeInBits)

    • checkTagSize

      protected final void checkTagSize(org.bouncycastle.asn1.x509.AlgorithmIdentifier contentAlgorithm) throws CMSTagLengthException
      Refuse an AEAD content algorithm whose authentication tag is shorter than the configured minimum. A no-op when no minimum is set or when the content algorithm is not AEAD.
      Parameters:
      contentAlgorithm - the content-encryption AlgorithmIdentifier (carries the AEAD ICV length).
      Throws:
      CMSTagLengthException - if the tag size is below the configured minimum.
