<summary>The Signature class is used to provide applications the functionality
of a digital signature algorithm.</summary>
<remarks>
<para>The Signature class is used to provide applications the functionality
of a digital signature algorithm. Digital signatures are used for
authentication and integrity assurance of digital data.</para>
<para>The signature algorithm can be, among others, the NIST standard
DSA, using DSA and SHA-1. The DSA algorithm using the
SHA-1 message digest algorithm can be specified as <c>SHA1withDSA</c>.
In the case of RSA, there are multiple choices for the message digest
algorithm, so the signing algorithm could be specified as, for example,
<c>MD2withRSA</c>, <c>MD5withRSA</c>, or <c>SHA1withRSA</c>.
The algorithm name must be specified, as there is no default.</para>
<para>A Signature object can be used to generate and verify digital
signatures.</para>
<para>There are three phases to the use of a Signature object for
either signing data or verifying a signature:<ol>
<li>Initialization, with either
<ul>
<li>a public key, which initializes the signature for
verification (see <c>#initVerify(PublicKey) initVerify</c>), or
<li>a private key (and optionally a Secure Random Number Generator),
which initializes the signature for signing
(see <c>#initSign(PrivateKey)</c>
and <c>#initSign(PrivateKey, SecureRandom)</c>).
</ul>
<li>Updating</para>
<para>Depending on the type of initialization, this will update the
bytes to be signed or verified. See the
<c>#update(byte) update</c> methods.
<li>Signing or Verifying a signature on all updated bytes. See the
<c>#sign() sign</c> methods and the <c>#verify(byte[]) verify</c>
method.
</ol></para>
<para>Note that this class is abstract and extends from
<c>SignatureSpi</c> for historical reasons.
Application developers should only take notice of the methods defined in
this <c>Signature</c> class; all the methods in
the superclass are intended for cryptographic service providers who wish to
supply their own implementations of digital signature algorithms.</para>
<para>Android provides the following <c>Signature</c> algorithms:

<remarks>
<para>Sets the specified algorithm parameter to the specified value.
This method supplies a general-purpose mechanism through
which it is possible to set the various parameters of this object.
A parameter may be any settable parameter for the algorithm, such as
a parameter size, or a source of random bits for signature generation
(if appropriate), or an indication of whether or not to perform
a specific but optional computation. A uniform algorithm-specific
naming scheme for each parameter is desirable but left unspecified
at this time.</para>
