  • Method Details

    • values

      public static KeyUsageBits[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static KeyUsageBits valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • getMask

      public int getMask()
      Returns:
      Bit mask value.

    • isSet

      public boolean isSet(org.bouncycastle.asn1.x509.KeyUsage keyUsage)
      Determines whether this key usage bit is set in the given key usage value.
      Parameters:
      keyUsage - BC key usage object.
      Returns:
      True if bit is set, false otherwise.

    • isSet

      public boolean isSet(byte[] bitString)
      Determines whether this key usage bit is set in the given key usage bit string.
      Parameters:
      bitString - Key usage bit string as a byte array.
      Returns:
      True if bit is set, false otherwise.

    • isSet

      public boolean isSet(int bitString)
      Determines whether this key usage bit is set in the given key usage bit string.
      Parameters:
      bitString - Key usage bit string as a big endian integer.
      Returns:
      True if bit is set, false otherwise.

    • usage

      public static int usage(KeyUsageBits... bits)
      Computes the key usage value from one or more key usage bits.
      Parameters:
      bits - One or more key usage bits.
      Returns:
      Key usage bit string as an integer.
