Time Stamp Server URL

This option appears only for signature fields. Specifies the URL for the time-stamp server. Timestamps specify the date and time when a document or data was signed. Using an external server to append a timestamp to a digital signature removes any doubt about when the document was signed. Acrobat or Adobe Reader selects a time-stamp server in the following order of priority:

1. Uses the time-stamp server that is set in the Security Settings console

2. Uses the time-stamp server that is listed as an extension in the digital ID

3. Uses the specified time-stamp server first

Require the signing party to use the specified time stamp server

This option appears only for signature fields. Forces Acrobat to append a timestamp to a digital signature when the document is signed. If you select this option, Acrobat or Adobe Reader selects a time-stamp server; however, if a valid timestamp is not returned, the signing will fail and the signature will not be created. If you do not select this option, Acrobat or Adobe Reader selects a time-stamp server; however, if a valid time-stamp server is not returned, the signing will still continue.

Include the CRL or OCSP response when signing

ncludes the CRL or OCSP response in the signature when the document or data is signed. The signing party must have access to the Internet to retrieve the CRL or OCSP response from the appropriate server.

Require in order for signing to succeed

Requires the CRL or OCSP response for signing to succeed.

Signing Server URL

Points to a web service that holds the digital credentials that a signing party uses to sign a document or data.

Restrict signing to specified URL server

Forces Acrobat to search for the credentials on the specified server. If this option is not selected, the server is only suggested; Acrobat can use other available credentials if the specified server is not available. If the server is available, it must use credentials even if they are not required. If you do not require a specific roaming credential server, Acrobat uses any digital ID regardless of its location.
