Windows PowerShell command on Get-command New-NetIPsecMainModeCryptoProposal

NAME
    New-NetIPsecMainModeCryptoProposal
    
SYNOPSIS
    Creates a main mode cryptographic proposal that specifies a suite of cryptographic protocols to offer in IPsec 
    main mode negotiations with other computers.
    
    
SYNTAX
    New-NetIPsecMainModeCryptoProposal [-Encryption ] [-Hash ] [-KeyExchange 
    ] []
    
    
DESCRIPTION
    The New-NetIPsecMainModeCryptoProposal cmdlet creates a single cryptographic proposal to be used in main mode 
    negotiations.
    
    A NetIPsecMainModeCryptoProposal object provides three of the mandatory four parameters for the negotiation of a 
    main mode security association (SA): The encryption algorithm is provided in the Encryption parameter, the hashing 
    algorithm in the Hash parameter, and the Diffie-Hellman (DH) key exchange group to be used for the base keying 
    material in the KeyExchange parameter. The remaining parameter; the authentication method, such as Kerberos v5, 
    certificate, or pre-shared key authentication, is given through NetIPsecPhase1AuthSet and NetIPsecPhase2AuthSet 
    objects.
    
    Multiple NetIPsecMainModeCryptoProposal fields are grouped into a single NetIPsecMainModeCryptoSet object. The 
    main mode exchange will use the first proposal that the responder has in common with the sender. A 
    NetIPsecPhase1AuthSet object and a NetIPsecMainModeCryptoSet object get associated to a NetIPsecMainModeRule 
    object to provide all the necessary SA parameters for customized main mode negotiations.
    

PARAMETERS
    -Encryption 
        Specifies the encryption algorithm to use for IPsec main mode security association negotiations. The block 
        size of the encryption and hashing algorithms must be the same. 
        The acceptable values for this parameter are: None, DES, DES3, AES128, AES192, AES256, AESGCM128, AESGCM192, 
        or AESGCM256. 
                                 
        None implies Null Encryption per the RFC standard. 
                                 
        The default value is AES256. 
        Note: Neither GCM, for encryption, nor GMAC, for hashing, are supported in main mode. These are quick mode 
        only.
        
        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        
    -Hash 
        Specifies the hashing function to use for IPsec main mode security association negotiations. The block size of 
        the encryption and hashing algorithms should be the same. 
        The acceptable values for this parameter are: None, MD5, SHA1, SHA256, SHA384, AESGMAC128, AESGMAC192, or 
        AESGMAC256. 
                                 
        The default value is SHA384.
        
        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        
    -KeyExchange 
        Specifies the Diffie-Hellman group to use for IPsec main mode security association negotiations. 
        The acceptable values for this parameter are:ÿ None, DH1, DH2, DH14, DH19, DH20, or DH24. 
                                 
        The default value is None. 
        Note: SameAsMainMode is only valid for proposals added to quick mode cryptographic sets with 
        PerfectForwardSecrecyGroup (PFS) specified using SameAsMainMode.
        
        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        
    
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer, PipelineVariable, and OutVariable. For more information, see 
        about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).

        None
    
        
    
    
OUTPUTS
        Microsoft.Management.Infrastructure.CimInstance#root\StandardCimv2\NetIPsecMainModeCryptoProposal
    
        The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management 
        Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the 
        underlying WMI object.
    
    
    EXAMPLE 1
    
    PS C:\>$proposal1 = (New-NetIPsecMainModeCryptoProposal -Encryption DES3 -Hash MD5 -KeyExchange DH1)
    
    
    
    PS C:\>$proposal2 = (New-NetIPsecMainModeCryptoProposal -Encryption AES192 -Hash MD5 -KeyExchange DH14)
    
    
    
    PS C:\>$proposal3 = (New-NetIPsecMainModeCryptoProposal -Encryption DES3 -Hash MD5 -KeyExchange DH19)
    
    
    
    PS C:\>$mMCryptoSet= (New-NetIPsecMainModeCryptoSet -DisplayName "Main Mode Crypto Set" -Proposal 
    $proposal1,$proposal2,$proposal3)
    
    
    This cmdlet shows an alternative method of accomplishing the previous steps.
    PS C:\>$mMCryptoSet = New-NetIPsecMainModeCryptoSet -DisplayName "Main Mode Crypto Set" -Proposal 
    (New-NetIPsecMainModeCryptoProposal -Encryption DES3 -Hash MD5 -KeyExchange 
    DH1),(New-NetIPsecMainModeCryptoProposal -Encryption AES192 -Hash MD5 -KeyExchange 
    DH14),(New-NetIPsecMainModeCryptoProposal -Encryption DES3 -Hash MD5 -KeyExchange DH19)
    
    
    
    PS C:\>New-NetIPsecMainModeRule -DisplayName "Main Mode Rule" -MainModeCryptoSet $mMCryptoSet.Name
    
    This example creates a main mode rule linked to a cryptographic set that contains three cryptographic proposals.
