AlgorithmParametersSpi

This class defines the Service Provider Interface (SPI) for the {@code AlgorithmParameters} class, which is used to manage algorithm parameters.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply parameter management for a particular algorithm.

Functions

engineGetEncoded byte[] engineGetEncoded(): Returns the parameters in their primary encoding format. The primary encoding format for parameters is ASN.1, if an ASN.1 specification for this type of parameters exists.
engineGetEncoded byte[] engineGetEncoded(string format): Returns the parameters encoded in the specified format. If {@code format} is null, the primary encoding format for parameters is used. The primary encoding format is ASN.1, if an ASN.1 specification for these parameters exists.
engineInit void engineInit(AlgorithmParameterSpec paramSpec): Initializes this parameters object using the parameters specified in {@code paramSpec}.
engineInit void engineInit(byte[] params): Imports the specified parameters and decodes them according to the primary decoding format for parameters. The primary decoding format for parameters is ASN.1, if an ASN.1 specification for this type of parameters exists.
engineInit void engineInit(byte[] params, string format): Imports the parameters from {@code params} and decodes them according to the specified decoding format. If {@code format} is null, the primary decoding format for parameters is used. The primary decoding format is ASN.1, if an ASN.1 specification for these parameters exists.
engineToString string engineToString(): Returns a formatted string describing the parameters.
