Useful TPM PowerShell CmdLets

TPM (Trusted Platform Module) is a hardware-based security feature that is designed to provide a secure foundation for various security-related tasks, such as encryption, digital signatures, and platform authentication. Microsoft provides a set of PowerShell cmdlets for managing TPM on Windows systems. Here are some of the commonly used TPM PowerShell cmdlets:

1. Initialize-Tpm: This cmdlet initializes the TPM and creates the necessary owner authorization value. This cmdlet is used when the TPM is not yet initialized.
2. Get-Tpm: This cmdlet retrieves information about the TPM, such as its status, manufacturer, firmware version, and more.
3. Clear-Tpm: This cmdlet clears the TPM and removes all the data stored in it. This cmdlet is used when the TPM needs to be reset.
4. Enable-TpmAutoProvisioning: This cmdlet enables automatic provisioning of the TPM. This feature allows the TPM to automatically generate and manage the necessary keys for BitLocker encryption.
5. Import-TpmOwnerAuth: This cmdlet imports the owner authorization value into the TPM. This value is used to authenticate the owner of the TPM and to perform sensitive operations, such as clearing or changing the owner password.
6. Protect-CmsMessage: This cmdlet uses the TPM to protect a CMS (Cryptographic Message Syntax) message. The protected message can only be decrypted using the same TPM that was used to encrypt it.
7. Unprotect-CmsMessage: This cmdlet uses the TPM to unprotect a CMS message that was previously protected using the Protect-CmsMessage cmdlet.

These are just a few examples of the TPM PowerShell cmdlets available in Windows. There are many more cmdlets available that can be used to manage the TPM and perform various security-related tasks. You can learn more about TPM from below URL
