-- **Provider Name** - Optional. To get a list of Crypto Providers, open PowerShell and issue the 'certutil -csplist' command.  If no Provider Name is provided, the 'Microsoft Strong Cryptographic Provider' will be used.
-- **SAN** - Required.  The SAN must have one entry that matches the Subject Name when using ReEnrollment.  Multiple SANs maybe chained together using '&'.  Example: dns=www.mysite.com&dns=www.mysite2.com.
+- **Provider Name** - Optional. Name of the Windows cryptographic provider to use when generating and storing the private key for the certificate being enrolled by a reenrollment job. If not specified, defaults to 'Microsoft Strong Cryptographic Provider'. This value would typically be changed when leveraging a Hardware Security Module (HSM). The specified cryptographic provider must be available on the target IIS server being managed. The list of installed cryptographic providers can be obtained by running 'certutil -csplist' in a command shell on the target IIS Server.

+- **SAN** - Required. Specifies Subject Alternative Name (SAN) to be used when performing reenrollment jobs. Certificate templates generally require a SAN that matches the subject of the certificate (per RFC 2818). Format is a list of <san_type>=<san_value> entries separated by ampersands. Examples: 'dns=www.mysite.com' for a single SAN or 'dns=www.mysite.com&dns=www.mysite2.com' for multiple SANs.
