public class C509ConversionOptions
extends Object

Options controlling the conversion of an X.509 certificate to C509.

Field Summary

Fields

Modifier and Type	Field	Description
static final C509ConversionOptions	DEFAULT	The default options: elliptic curve points are compressed and the ECDSA signature component width is derived from the signature itself.

Method Summary

Modifier and Type	Method	Description
C509ConversionOptions	withEcdsaSignatureValueWidth(int width)	Return a copy of these options with a fixed octet width for the components of an ECDSA style signature value (Section 3.2.2 - for example 32 for P-256).
C509ConversionOptions	withPointCompression(boolean pointCompression)	Return a copy of these options with point compression turned on or off.

Field Details

DEFAULT

public static final C509ConversionOptions DEFAULT

The default options: elliptic curve points are compressed and the ECDSA signature component width is derived from the signature itself.

Method Details

withPointCompression

public C509ConversionOptions withPointCompression(boolean pointCompression)

Return a copy of these options with point compression turned on or off. When on (the default), an uncompressed id-ecPublicKey subjectPublicKey is stored in compressed form - for a re-encoded certificate using the 0xfe/0xfd markers of Section 3.2.1 so the original DER can be recovered.

withEcdsaSignatureValueWidth

public C509ConversionOptions withEcdsaSignatureValueWidth(int width)

Return a copy of these options with a fixed octet width for the components of an ECDSA style signature value (Section 3.2.2 - for example 32 for P-256). The default of 0 derives the width from the signature's own component lengths, rounded up to the width of the nearest common curve.
