java.lang.Enum<EcParameterSpecWithName.SpecifiedECDomainVersion>

com.entrust.toolkit.security.crypto.ec.EcParameterSpecWithName.SpecifiedECDomainVersion

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<EcParameterSpecWithName.SpecifiedECDomainVersion>

Enclosing class:

EcParameterSpecWithName

public static enum EcParameterSpecWithName.SpecifiedECDomainVersion
extends java.lang.Enum<EcParameterSpecWithName.SpecifiedECDomainVersion>

Specifies the version number of elliptic curve domain parameters in specified format.

This enumeration represent the values supported by the SpecifiedECDomainVersion ASN.1 structure from ANSI X9.63-2005:

 SpecifiedECDomainVersion ::= INTEGER {
    ecdpVer1(1),
    ecdpVer2(2),
    ecdpVer3(3),
    ...-- More values may added
 }
 

Since:

8.0

Enum Constant Summary

Enum Constants

Enum Constant and Description
ecdpVer1 Indicates that the elliptic curve may or may not be verifiably random according to whether curve.seed is present, and the base point G is not verifiably random.
ecdpVer2 Indicates that the elliptic curve and base point G are both verifiably random (in this case, curve.seed shall be present).
ecdpVer3 Indicates that the elliptic curve is not verifiably random but that the base point G is verifiably random (in this case, curve.seed shall be present).

Enum Constant Detail

ecdpVer1

public static final EcParameterSpecWithName.SpecifiedECDomainVersion ecdpVer1

Indicates that the elliptic curve may or may not be verifiably random according to whether curve.seed is present, and the base point G is not verifiably random.

ecdpVer2

public static final EcParameterSpecWithName.SpecifiedECDomainVersion ecdpVer2

Indicates that the elliptic curve and base point G are both verifiably random (in this case, curve.seed shall be present).

ecdpVer3

public static final EcParameterSpecWithName.SpecifiedECDomainVersion ecdpVer3

Indicates that the elliptic curve is not verifiably random but that the base point G is verifiably random (in this case, curve.seed shall be present).

Method Detail

values

public static EcParameterSpecWithName.SpecifiedECDomainVersion[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (EcParameterSpecWithName.SpecifiedECDomainVersion c : EcParameterSpecWithName.SpecifiedECDomainVersion.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static EcParameterSpecWithName.SpecifiedECDomainVersion valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

valueOf

public static EcParameterSpecWithName.SpecifiedECDomainVersion valueOf(int version)
                                                                throws java.lang.IllegalArgumentException

Converts an EC domain parameter version from integer representation to SpecifiedECDomainVersion representation.

Parameters:

version - the EC domain parameter version (integer representation)

Returns:

the EC domain parameter version ( SpecifiedECDomainVersion representation)

Throws:

java.lang.IllegalArgumentException - if the EC domain parameter version is unsupported

getVersion

public int getVersion()

Returns the EC domain parameter version.

Returns:

the EC domain parameter version (integer representation)
