    Creates container encryption specifications for installing from encrypted containers.

    Parameters:

    encryptionAlgorithm - encryption algorithm to use; format matches JCE

    encryptionSpec - algorithm parameter specification

    encryptionKey - key used for decryption

    macAlgorithm - MAC algorithm to use; format matches JCE

    macSpec - algorithm parameters specification, may be null

    macKey - key used for authentication (i.e., for the MAC tag)

    macTag - message authentication code (MAC) tag for the authenticated data

    authenticatedDataStart - offset of start of authenticated data in stream

    encryptedDataStart - offset of start of encrypted data in stream

    dataEnd - offset of the end of both the authenticated and encrypted data

  • describeContents

    public int describeContents()

    Description copied from interface: Parcelable
    Describe the kinds of special objects contained in this Parcelable's marshalled representation.

    Specified by:

    describeContents in interface Parcelable

    Returns:

    a bitmask indicating the set of special object types marshalled by the Parcelable.

  • equals

    public boolean equals(Object o)

    Description copied from class: Object
    Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

    The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

    The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

    Overrides:

    equals in class Object

    Parameters:

    o - the object to compare this instance with.

    Returns:

    true if the specified object is equal to this Object; false otherwise.

    See Also:

    Object.hashCode()

  • hashCode

    public int hashCode()

    Description copied from class: Object
    Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

    Note that hash values must not change over time unless information used in equals comparisons also changes.

    See Writing a correct hashCode method if you intend implementing your own hashCode method.

    Overrides:

    hashCode in class Object

    Returns:

    this object's hash code.

    See Also:

    Object.equals(java.lang.Object)

  • toString

    public String toString()

    Description copied from class: Object
    Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

       getClass().getName() + '@' + Integer.toHexString(hashCode())

    See Writing a useful toString method if you intend implementing your own toString method.

    Overrides:

    toString in class Object

    Returns:

    a printable representation of this object.

  • writeToParcel

    public void writeToParcel(Parcel dest,
                     int flags)

    Description copied from interface: Parcelable
    Flatten this object in to a Parcel.

    Specified by:

    writeToParcel in interface Parcelable

    Parameters:

    dest - The Parcel in which the object should be written.

    flags - Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
