Source:: CertificateRequest.cs

Source:: CertificateRequest.cs

Source:: CertificateRequest.cs

Creates a certificate using the established subject, key, and optional extensions using the specified certificate as the issuer.

public:
 System::Security::Cryptography::X509Certificates::X509Certificate2 ^ Create(System::Security::Cryptography::X509Certificates::X509Certificate2 ^ issuerCertificate, DateTimeOffset notBefore, DateTimeOffset notAfter, cli::array <System::Byte> ^ serialNumber);

public System.Security.Cryptography.X509Certificates.X509Certificate2 Create (System.Security.Cryptography.X509Certificates.X509Certificate2 issuerCertificate, DateTimeOffset notBefore, DateTimeOffset notAfter, byte[] serialNumber);

member this.Create : System.Security.Cryptography.X509Certificates.X509Certificate2 * DateTimeOffset * DateTimeOffset * byte[] -> System.Security.Cryptography.X509Certificates.X509Certificate2

Public Function Create (issuerCertificate As X509Certificate2, notBefore As DateTimeOffset, notAfter As DateTimeOffset, serialNumber As Byte()) As X509Certificate2

Parameters

issuerCertificate: X509Certificate2

An X509Certificate2 instance representing the issuing Certificate Authority (CA).

notBefore: DateTimeOffset

The oldest date and time when this certificate is considered valid. Typically UtcNow, plus or minus a few seconds.

notAfter: DateTimeOffset

The date and time when this certificate is no longer considered valid.

serialNumber: Byte[]

The serial number to use for the new certificate. This value should be unique per issuer. The value is interpreted as an unsigned integer of arbitrary size in big-endian byte ordering. RFC 3280 recommends confining it to 20 bytes or less.

Returns

X509Certificate2

An X509Certificate2 object with the specified values. The returned object won't assert HasPrivateKey.

Exceptions

ArgumentNullException

issuerCertificate is null.

ArgumentException

The issuerCertificate doesn't contain a private key.

-or-

The type of signing key represented by issuerCertificate couldn't be determined.

-or-

notAfter represents a date and time that happens earlier than notBefore.

-or-

serialNumber is zero length or null.

-or-

issuerCertificate has a different key algorithm than the requested certificate.

-or-

The HasPrivateKey value for issuerCertificate is false.

InvalidOperationException

issuerCertificate is an RSA certificate and the current object was created using a constructor that doesn't accept a padding parameter.

ArgumentOutOfRangeException

The HashAlgorithm property value is not supported.

Remarks

This method does not support using MD5 or SHA-1 as the hash algorithm for the certificate signature. If you need an MD5 or SHA-1 based certificate signature, you need to implement a custom X509SignatureGenerator and call Create(X500DistinguishedName, X509SignatureGenerator, DateTimeOffset, DateTimeOffset, Byte[]).
