Class DHParameters
A JCE-specific Data Access Object (DAO) for DH parameters.
protected byte[] | engineGetEncoded() - Encodes the set of DH parameters as per RFC-2459; i.e. as the DER-encoded
form of the following ASN.1 construct:
DhParams ::= SEQUENCE {
p INTEGER, -- odd prime, p=jq +1
g INTEGER, -- generator, g
q INTEGER -- factor of p-1
}
|
protected byte[] | engineGetEncoded(String format) - Returns the parameters in the specified encoding format.
|
protected AlgorithmParameterSpec | engineGetParameterSpec(Class<T> paramSpec)
|
protected void | engineInit(byte[] params) - Decodes the set of DH parameters as per RFC-2459; i.e. the DER-encoded
form of the following ASN.1 construct:
DhParams ::= SEQUENCE {
p INTEGER, -- odd prime, p=jq +1
g INTEGER, -- generator, g
q INTEGER -- factor of p-1
}
|
protected void | engineInit(byte[] params, String format) - Initializes the engine with the specified
parameters stored in the byte array and decodes them
according to the specified decoding specification.
|
protected void | engineInit(AlgorithmParameterSpec spec) - Initializes the engine with the specified
AlgorithmParameterSpec class.
|
protected String | engineToString() - Returns a string describing the parameters in the
AlgorithmParametersSpi class.

protected byte[] engineGetEncoded()
throws IOException
Encodes the set of DH parameters as per RFC-2459; i.e. as the DER-encoded
form of the following ASN.1 construct:
DhParams ::= SEQUENCE {
p INTEGER, -- odd prime, p=jq +1
g INTEGER, -- generator, g
q INTEGER -- factor of p-1
}
- engineGetEncoded in interface AlgorithmParametersSpi
engineInit
protected void engineInit(byte[] params)
throws IOException
Decodes the set of DH parameters as per RFC-2459; i.e. the DER-encoded
form of the following ASN.1 construct:
DhParams ::= SEQUENCE {
p INTEGER, -- odd prime, p=jq +1
g INTEGER, -- generator, g

}
- engineInit in interface AlgorithmParametersSpi
engineInit
protected void engineInit(byte[] params,
String format)
throws IOException
Initializes the engine with the specified
parameters stored in the byte array and decodes them
according to the specified decoding specification.
If format is null, then it is decoded using the ASN.1
specification if it exists or else it throws
IOException.
