详细说明
The New-SelfSignedCertificate cmdlet creates a self-signed certificate for testing purposes. Using the CloneCert parameter, a test certificate can be created based on an existing certificate with all settings copied from the original certificate except for the public key. The cmdlet creates a new key of the same algorithm and length.
Delegation may be required when using this cmdlet with Windows PowerShell remoting and changing user configuration.
参数
-AlternateSignatureAlgorithm
Indicates that this cmdlet uses RSA-PSS (PKCSv2.1) or an elliptic curve cryptography (ECC) equivalent. If you do not specify this parameter, the cmdlet uses the default, RSA-PSS (PKCSv1.5) or an ECC equivalent.

-CertStoreLocation<String>
Specifies the certificate store in which to store the new certificate. If the current path is Cert:\CurrentUser or Cert:\CurrentUser\My, the default store is Cert:\CurrentUser\My. If the current path is Cert:\LocalMachine or Cert:\LocalMachine\My, the default store is Cert:\LocalMachine\My. Otherwise, you must specify Cert:\CurrentUser\My or Cert:\LocalMachine\My for this parameter. This parameter does not support other certificate stores.

-CloneCert<Certificate>
Identifies the certificate to copy when creating a new certificate. The certificate being cloned can be identified by an X509 certificate or the file path in the certificate provider. When this parameter is used, all fields and extensions of the certificate will be inherited except the public key, a new key of the same algorithm and length will be created, and the NotAfter and NotBefore fields. The default validity period will be the same as the certificate to copy, except that the NotBefore field will be set to ten minutes in the past.

-Container<System.String>
Specifies the name of the container in which this cmdlet stores the key for the new certificate.
When you create a key, a trailing asterisk (*) indicates that the rest of the container name string is a prefix. An appended GUID string makes the container name unique.
When you use an existing key, the container name must identify an existing key. You may also have to specify the provider.

-TextExtension<System.String[]>
Specifies an array of certificate extensions, as strings, which this cmdlet includes in the new certificate. Each string must employ one of the following formats:
oid=
base64String, where oid is the object identifier of the extension and base64String is a value that you provide. After decoding base64String, the value must be valid Abstract Syntax Notation One (ASN.1). For more information, see Abstract Syntax Notation One (ASN.1): Specification of basic notation (http://www.itu.int/ITU-T/studygroups/com17/languages/X.680-0207.pdf).
oid={hex}
hexidecimalString, where oid is the object identifier of the extension and hexidecimalString is a value that you provide. After decoding hexidecimalString, the value must be valid ASN.1.
oid={text}
String, where oid is the object identifier of the extension and String is a value that you provide. String must contain a textual representation of the extension value in a format specific to each object ID. When String is processed, it will be encoded into an ASN.1 extension value before being placed into the new certificate as an extension.
To specify that an extension is critical, insert {critical} immediately following oid=
in any of the previous cases.
The object identifiers of some common extensions are as follows:

示例
EXAMPLE 1
This example creates a self-signed SSL server certificate in the computer MY store with the subject alternative name set to www.fabrikam.com, www.contoso.com and Subject and Issuer name set to www.fabrikam.com.
PS C:\> New-SelfSignedCertificate -DnsName "www.fabrikam.com", "www.contoso.com" -CertStoreLocation "cert:\LocalMachine\My"
EXAMPLE 2
This example creates a copy of the certificate specified by the CloneCert parameter and puts it in the computer MY store.
PS C:\> Set-Location -Path "cert:\LocalMachine\My"
PS Cert:\LocalMachine\My> $OldCert = (Get-ChildItem -Path E42DBC3B3F2771990A9B3E35D0C3C422779DACD7)
PS Cert:\LocalMachine\My> New-SelfSignedCertificate -CloneCert $OldCert
EXAMPLE 3
This example creates a self-signed S/MIME certificate in the user MY store. The certificate uses the default provider, which is the Microsoft Software Key Storage Provider. The certificate uses an RSA asymmetric key with a key size of 2048 bits. This certificate has the subject alternative names of patti.fuller@contosol.com and pattifuller@contoso.com.
This command does not specify the NotAfter parameter. Therefore, the certificate expires in one year.
PS C:\> New-SelfSignedCertificate -Type Custom -Subject "E=patti.fuller@contoso.com,CN=Patti Fuller" -TextExtension @("2.5.29.37={text}1.3.6.1.5.5.7.3.4","2.5.29.17={text}email=patti.fuller@contoso.com&upn=pattifuller@contoso.com") -KeyUsage DataEncipherment -KeyAlgorithm RSA -KeyLength 2048 -SmimeCapabilities -CertStoreLocation "Cert:\CurrentUser\My"
EXAMPLE 4
This example creates a self-signed client authentication certificate in the user MY store. The certificate uses the default provider, which is the Microsoft Software Key Storage Provider. The certificate uses an RSA asymmetric key with a key size of 2048 bits. The certificate has a subject alternative name of pattifuller@contoso.com.
The certificate expires in one year.
PS C:\> New-SelfSignedCertificate -Type Custom -Subject "CN=Patti Fuller,OU=UserAccounts,DC=corp,DC=contoso,DC=com" -TextExtension @("2.5.29.37={text}1.3.6.1.5.5.7.3.2","2.5.29.17={text}upn=pattifuller@contoso.com") -KeyUsage DigitalSignature -KeyAlgorithm RSA -KeyLength 2048 -CertStoreLocation "Cert:\CurrentUser\My"
EXAMPLE 5
This example creates a self-signed client authentication certificate in the user MY store. The certificate uses the default provider, which is the Microsoft Software Key Storage Provider. The certificate uses an elliptic curve asymmetric key and the curve parameters nist256, which creates a 256-bit key. The subject alternative name is pattifuller@contoso.com.
The certificate expires in one year.

EXAMPLE 6
This example creates a self-signed client authentication certificate in the user MY store. The certificate uses the Microsoft Platform Crypto Provider. This provider uses the Trusted Platform Module (TPM) of the device to create the asymmetric key. The key is an RSA 2048-bit key that cannot be exported. The subject alternative name is pattifuller@contoso.com. The certificate expires in one year.

EXAMPLE 7
This example creates a self-signed client authentication certificate in the user MY store. The certificate uses the default provider, which is the Microsoft Software Key Storage Provider. The certificate uses an RSA asymmetric key with a key size of 2048 bits. The subject alternative name is pattifuller@contoso.com.
This command specifies a value for NotAfter. The certificate expires in six months.
