X9ECParameters.toASN1Primitive介绍

[英]Produce an object suitable for an ASN1OutputStream.

ECParameters ::= SEQUENCE { 
version         INTEGER { ecpVer1(1) } (ecpVer1), 
fieldID         FieldID {{FieldTypes}}, 
curve           X9Curve, 
base            X9ECPoint, 
order           INTEGER, 
cofactor        INTEGER OPTIONAL 
}

[中]生成适合ASN1OutputStream的对象

ECParameters ::= SEQUENCE { 
version         INTEGER { ecpVer1(1) } (ecpVer1), 
fieldID         FieldID {{FieldTypes}}, 
curve           X9Curve, 
base            X9ECPoint, 
order           INTEGER, 
cofactor        INTEGER OPTIONAL 
}
