/**@class java.security.AlgorithmParameters @extends java.lang.Object This class is used as an opaque representation of cryptographic parameters. <p>An {@code AlgorithmParameters} object for managing the parameters for a particular algorithm can be obtained by calling one of the {@code getInstance} factory methods (static methods that return instances of a given class). <p>Once an {@code AlgorithmParameters} object is obtained, it must be initialized via a call to {@code init}, using an appropriate parameter specification or parameter encoding. <p>A transparent parameter specification is obtained from an {@code AlgorithmParameters} object via a call to {@code getParameterSpec}, and a byte encoding of the parameters is obtained via a call to {@code getEncoded}. <p> Android provides the following <code>AlgorithmParameters</code> algorithms: <table> <thead> <tr> <th>Algorithm</th> <th>Supported API Levels</th> </tr> </thead> <tbody> <tr> <td>AES</td> <td>1+</td> </tr> <tr> <td>BLOWFISH</td> <td>10+</td> </tr> <tr> <td>ChaCha20</td> <td>28+</td> </tr> <tr> <td>DES</td> <td>1+</td> </tr> <tr> <td>DESede</td> <td>1+</td> </tr> <tr> <td>DH</td> <td>1+</td> </tr> <tr> <td>DSA</td> <td>1+</td> </tr> <tr> <td>EC</td> <td>26+</td> </tr> <tr> <td>GCM</td> <td>22+</td> </tr> <tr class="deprecated"> <td>IES</td> <td>1-8</td> </tr> <tr> <td>OAEP</td> <td>1+</td> </tr> <tr> <td>PBEwithHmacSHA1AndAES_128</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA1AndAES_256</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA224AndAES_128</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA224AndAES_256</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA256AndAES_128</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA256AndAES_256</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA384AndAES_128</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA384AndAES_256</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA512AndAES_128</td> <td>26+</td> </tr> <tr> <td>PBEwithHmacSHA512AndAES_256</td> <td>26+</td> </tr> <tr> <td>PKCS12PBE</td> <td>1+</td> </tr> <tr> <td>PSS</td> <td>1-8,24+</td> </tr> </tbody> </table> These algorithms are described in the <a href= "https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html#AlgorithmParameters"> AlgorithmParameters section</a> of the Java Cryptography Architecture Standard Algorithm Name Documentation. @author Jan Luehe @see java.security.spec.AlgorithmParameterSpec @see java.security.spec.DSAParameterSpec @see KeyPairGenerator @since 1.2 */ var AlgorithmParameters = { /**Returns the name of the algorithm associated with this parameter object. @return {String} the algorithm name. */ getAlgorithm : function( ) {}, /**Returns a parameter object for the specified algorithm. <p> This method traverses the list of registered security Providers, starting with the most preferred Provider.
