      Parameters:
      usage - the keyPurposeId to be included.

    • ExtendedKeyUsage

      public ExtendedKeyUsage(KeyPurposeId[] usages)
      Base constructor, from multiple KeyPurposeIds.
      Parameters:
      usages - an array of KeyPurposeIds.

    • ExtendedKeyUsage

      public ExtendedKeyUsage(Vector usages)
      Deprecated.
      use KeyPurposeId[] constructor.

  • Method Details

    • getInstance

      public static ExtendedKeyUsage getInstance(ASN1TaggedObject obj, boolean explicit)
      Return an ExtendedKeyUsage from the passed in tagged object.
      Parameters:
      obj - the tagged object containing the ExtendedKeyUsage
      explicit - true if the tagged object should be interpreted as explicitly tagged, false if implicit.
      Returns:
      the ExtendedKeyUsage contained.

    • getInstance

      public static ExtendedKeyUsage getInstance(Object obj)
      Return an ExtendedKeyUsage from the passed in object.
      Parameters:
      obj - an ExtendedKeyUsage, some form or encoding of one, or null.
      Returns:
      an ExtendedKeyUsage object, or null if null is passed in.

    • fromExtensions

      public static ExtendedKeyUsage fromExtensions(Extensions extensions)
      Retrieve an ExtendedKeyUsage for a passed in Extensions object, if present.
      Parameters:
      extensions - the extensions object to be examined.
      Returns:
      the ExtendedKeyUsage, null if the extension is not present.

    • hasKeyPurposeId

      public boolean hasKeyPurposeId(KeyPurposeId keyPurposeId)
      Return true if this ExtendedKeyUsage object contains the passed in keyPurposeId.
      Parameters:
      keyPurposeId - the KeyPurposeId of interest.
      Returns:
      true if the keyPurposeId is present, false otherwise.

    • getUsages

      public KeyPurposeId[] getUsages()
      Returns all extended key usages.
      Returns:
      An array with all key purposes.

    • size

      public int size()
      Return the number of KeyPurposeIds present in this ExtendedKeyUsage.
      Returns:
      the number of KeyPurposeIds

    • toASN1Primitive

      public ASN1Primitive toASN1Primitive()
      Return the ASN.1 primitive form of this object.
      Specified by:
      toASN1Primitive in interface ASN1Encodable
      Specified by:
      toASN1Primitive in class ASN1Object
      Returns:
      an ASN1Sequence.
