If not specified, defaults to 'Microsoft Strong Cryptographic Provider'. This value would typically be specified when leveraging a Hardware Security Module (HSM). The specified cryptographic provider must be available on the target server being managed. The list of installed cryptographic providers can be obtained by running 'certutil -csplist' on the target Server.
 SAN | SAN | String || Reenrolling | 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. Can be made optional if RFC 2818 is disabled on the CA.
