Remarks
This class is used as an opaque representation of cryptographic parameters.
An AlgorithmParameters object for managing the parameters for a particular algorithm can be obtained by calling one of the getInstance factory methods (static methods that return instances of a given class).
Once an AlgorithmParameters object is obtained, it must be initialized via a call to init, using an appropriate parameter specification or parameter encoding.
A transparent parameter specification is obtained from an AlgorithmParameters object via a call to getParameterSpec, and a byte encoding of the parameters is obtained via a call to getEncoded.
Android provides the following AlgorithmParameters 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>
