class System.Security.Cryptography.X509Certificates.X509BasicConstraintsExtension
Assembly: System.Security.Cryptography
Inheritance: object → AsnEncodedData → X509Extension → X509BasicConstraintsExtension
Defines the constraints set on a certificate. This class cannot be inherited.
Properties
public
bool
CertificateAuthority
Gets a value indicating whether a certificate is a certificate authority (CA) certificate.
public
bool
HasPathLengthConstraint
Gets a value indicating whether a certificate has a restriction on the number of path levels it allows.
public
int
PathLengthConstraint
Gets the number of levels allowed in a certificate's path.
public
bool
Critical
Gets a Boolean value indicating whether the extension is critical.
public
Oid
Oid
Gets or sets the <see cref="T:System.Security.Cryptography.Oid" /> value for an <see cref="T:System.Security.Cryptography.AsnEncodedData" /> object.
public
byte[]
RawData
Gets or sets the Abstract Syntax Notation One (ASN.1)-encoded data represented in a byte array.
Methods
public
void
CopyFrom(AsnEncodedData asnEncodedData)
Initializes a new instance of the <see cref="T:System.Security.Cryptography.X509Certificates.X509BasicConstraintsExtension" /> class using an <see cref="T:System.Security.Cryptography.AsnEncodedData" /> object.
asnEncodedData
The encoded data to use to create the extension.
public static
X509BasicConstraintsExtension
CreateForCertificateAuthority(int? pathLengthConstraint = null)
Creates an instance of <see cref="T:System.Security.Cryptography.X509Certificates.X509BasicConstraintsExtension" /> appropriate for a certificate authority, optionally including a path length constraint value.
Returns The configured basic constraints extension.
pathLengthConstraint
The longest valid length of a certificate chain between the certificate containing this extension and an end-entity certificate.
The default is <see langword="null" /> , an unconstrained length.
public static
X509BasicConstraintsExtension
CreateForEndEntity(bool critical = false)
Creates an instance of <see cref="T:System.Security.Cryptography.X509Certificates.X509BasicConstraintsExtension" /> appropriate for an end-entity certificate, optionally marking the extension as critical.
Returns The configured basic constraints extension.
critical
<see langword="true" /> to mark the extension as critical; <see langword="false" /> otherwise.
The default is <see langword="false" /> .
public
string
Format(bool multiLine)
Inherited from AsnEncodedData
Returns a formatted version of the Abstract Syntax Notation One (ASN.1)-encoded data as a string.
Returns A formatted string that represents the Abstract Syntax Notation One (ASN.1)-encoded data.
multiLine
<see langword="true" /> if the return string should contain carriage returns; otherwise, <see langword="false" /> .
