A document value that represents the PDF document that the invisible signature field is added to.

If you provide a literal value, clicking the ellipsis button opens the Select Asset dialog box. (See About Select Asset .)

Signature Field Name

A string value for the name of the signature field to add. The fully qualified name of the signature field must be specified.

OCSP Options Spec

(Optional) An OCSPOptionSpec value that represents settings for using Online Certificate Status Protocol (OCSP) revocation checking. To provide a literal value, specify the following options.

URL to Consult Option: Sets the list and order of the OCSP servers used to perform the revocation check. Select one of these values:

UseAIAInCert:

(Default) Use the URL of an online certificate status protocol server specified in the Authority Information Access (AIA) extension in the certificate. The AIA extension is used to identify how to access certificate authority (CA) information and services for the issuer of the certificate.

LocalURL:

Use the specified URL for the OCSP server specified in the OCSP Server URL option.

UseAIAIfPresentElseLocal:

Use the URL of the OCSP server specified in the AIA extension in the certificate if present. If the AIA extension is not present in the certificate, use the URL that is configured in the OCSP Server URL.

UseAIAInSignerCert:

Use the URL of the OCSP server specified in the AIA extension in the OCSP request of the signer certificate.

OCSP Server URL:

Sets the URL of the configured OCSP server. The value is used only when the LocalURL or UseAIAIfPresentElseLocal values are in URL To Consult Option.

Revocation Check Style:

Sets the revocation-checking style that is used for verifying the trust status of the CRL provider’s certificate from its observed revocation status. Select one of these values:

Sets the URL of the configured OCSP server. The value is used only when the LocalURL or UseAIAIfPresentElseLocal values are in URL To Consult Option.

Revocation Check Style:

Sets the revocation-checking style that is used for verifying the trust status of the CRL provider’s certificate from its observed revocation status. Select one of these values:

NoCheck:

Does not check for revocation.

BestEffort:

Checks for revocation of all certificates when possible.

CheckIfAvailable:

(Default) Checks for revocation of all certificates only when revocation information is available.

AlwaysCheck:

Checks for revocation of all certificates.

Max Clock Skew Time (Minutes):

Sets the maximum allowed skew, in minutes, between response time and local time. Valid skew times are 0 - 2147483647 min. The default value is 5 min.

Response Freshness Time (Minutes):

Sets the maximum time, in minutes, for which a preconstructed OCSP response is considered valid. Valid response freshness times are 1 - 2147483647 min. The default value is 525600 min. (one year).

Send Nonce:

Select this option to send a nonce with the OCSP request. A nonce is a parameter that varies with time. These parameters can be a timestamp, a visit counter on a web page, or a special marker. The parameter is intended to limit or prevent the unauthorized replay or reproduction of a file. When the option deselected, a nonce is not sent with the request. By default, the option is selected.

Sign OCSP Request:

Select this option to specify that the OCSP request must be signed. When the option is deselected, the OCSP request does not need be signed. By default, the option deselected.

Request Signer Credential Alias:

Sets the credential alias used for signing the OCSP request when signing is enabled.

Go Online for OCSP:

When the option is deselected, OCSP checking is not retrieved from the network, and only embedded and cached OCSP information is used. By default, the option is selected.

Ignore Validity Dates:

Select this option to use the OCSP response thisUpdate and nextUpdate times. Ignoring these response times prevents any negative effect on response validity. The thisUpdate and nextUpdate times are retrieved from external sources by using HTTP or LDAP, and can be different for each revocation information. When the option is deselected, the thisUpdate and nextUpdate times are ignored. By default, the option is deselected.

Allow OCSP NoCheck Extension:

Select this option to allow an OCSPNoCheck extension in the response signing certificate. An OCSPNoCheck extension can be present in the OCSP Responder’s certificate to prevent infinite loops from occurring during the validation process. When the option is deselected, the OCSPNoCheck extension is not used. By default, the option is selected.

Require OCSP ISIS-MTT CertHash Extension:

Select this option to specify that certificate public key hash (CertHash) extensions must be present in OCSP responses. This extension is required for SigQ validation. SigQ compliance requires the CertHash extension to be in the OCSP responder certificate. Select this option when processing for SigQ compliance and supported OCSP responders. When the option is deselected, the CertHash extension presence in the OCSP response is not required. By default, the option is deselected.

Sets the maximum allowed skew, in minutes, between response time and local time. Valid skew times are 0 - 2147483647 min. The default value is 5 min.

Response Freshness Time (Minutes):

SigQ compliance requires the CertHash extension to be in the OCSP responder certificate. Select this option when processing for SigQ compliance and supported OCSP responders. When the option is deselected, the CertHash extension presence in the OCSP response is not required. By default, the option is deselected.

CRL Options Spec

(Optional) A CRLOptionSpec value that represents the certificate revocation list (CRL) preferences when CRL is used to perform revocation checking. If you provide a literal value, specify the following options.

Consult Local URI First:

Select this option to use the CRL location provided as a local URI before any specified locations within a certificate. The CRL location provided is used for revocation checking. When this option is selected, it means the local URI is used first. When this option is deselected, the locations specified in the certificate before using the local URI are used. By default, the option is deselected.

Local URI for CRL Lookup:

Sets the URL for the local CRL store. This value is used only if the Consult Local URI First option is selected. No default value is provided.

Revocation Check Style:

Sets the revocation-checking style used for verifying the trust status of the CRL provider’s certificate from its observed revocation status. Select one of these values:

• NoCheck: Does not check for revocation.

• BestEffort: (Default) Checks for revocation of all certificates when possible.

• CheckIfAvailable: Checks for revocation of all certificates only when revocation information is available.

• AlwaysCheck: Checks for revocation of all certificates.

LDAP Server:

Sets the URL or path of the Lightweight Directory Access Protocol (LDAP) server used to retrieve information about the certificate revocation list (CRL). The LDAP server searches for CRL information using the distinguished name (DN) according to the rules specified in RFC 3280 , section 4.2.1.14. For example, you can type www.ldap.com for the URL or ldap://ssl.ldap.com:200 for the path and port. No default value is provided.

Go Online for CRL Retrieval:

Select this option to access the network to retrieve CRL information. CRL information is cached on the server to improve network performance. CRL information is retrieved online only when necessary. When this option is deselected, CRL information is not retrieved online. By default, the option is selected.

Ignore Validity Dates:

Select this option to use thisUpdate and nextUpdate times. Ignoring the response’s thisUpdate and nextUpdate times prevents any negative effect on response validity. The thisUpdate and nextUpdate times are retrieved from external sources by using HTTP or LDAP and can be different for each revocation information. When the option is deselected, the thisUpdate and nextUpdate time are ignored. By default, the option deselected.

Require AKI Extension in CRL:

Select this option to specify that the Authority Key Identifier (AKI) extension must be present in the CRL. The AKI extension can be used for CRL validation. When this option is deselected, the presence of the AKI extension the CRL is not required. By default, the option is deselected.

Path Validation Options Spec

(Optional) A PathValidationOptionSpec that represents the settings that control RFC3280-related path validation options. For example, you can indicate whether policy mapping is allowed in the certification path. (See RFC 3280 ). If you provide a literal value, you can set the following options.

Require Explicit Policy:

Select this option to specify that the path must be valid for at least one of the certificate policies in the user initial policy set. When this option is deselected, the path validity is not required. By default, the option is deselected.

Inhibit Any Policy:

Select this option to specify that a policy object identifier (OID) must be processed if it is included in a certificate. When deselected, any policy can be selected. By default, the option is deselected.

Check All Paths:

Select this option to require that all paths to a trust anchor must be validated. When this option is deselected, all paths to a trust anchor are not validated. By default, the option is deselected.

Inhibit Policy Mapping:

Select this option to allow policy mapping in the certification path. When this option is deselect, policy mapping is not allowed in the certification path. By default, the option is deselected.

LDAP Server:

Sets the URL or path of the Lightweight Directory Access Protocol (LDAP) server used to retrieve information about the certificate revocation list (CRL). The LDAP server searches for CRL information using the distinguished name (DN) according to the rules specified in RFC 3280 , section 4.2.1.14. For example, you can type www.ldap.com for the URL or ldap://ssl.ldap.com:200 for the path and port. No default value is provided.

Follow URIs in Certificate AIA:

Select this option to specify to follow any URIs specified in the certificate’s Authority Information Access (AIA) extension for path discovery. The AIA extension specifies where to find up-to-date certificates. When this option is deselected, no URIs are processed in the AIA extension from the certificate. By default, the option is deselected.

Basic Constraints Extension Required in CA Certificates:

Select this option to specify that the certificate authority (CA) Basic Constraints certificate extension must be present for CA certificates. Some early German certified root certificates (7 and earlier) are not compliant to RFC 3280 and do not contain the basic constraint extension. If it is known that a user's EE certificate chains up to such a German root, deselect this option. When this option is deselected, the presence of the CA Basic Constraints certificate in CA certificates is not required. By default, the value is selected.

Require Valid Certificate Signature During Chain Building:

Select this option to require that all Digital Signature Algorithm (DSA) signatures on certificates be valid before a chain is built. For example, in a chain CA > ICA > EE where the signature for EE is not valid, the chain building stops at ICA. EEs are not included in the chain. When this option is deselected, the entire chain is built regardless of whether an invalid DSA signature is encountered. By default, the option is deselected.

TSP Options Spec

(Optional) A TSPOptionSpec value that represents the settings that define timestamp information applied to the certified signature.

If you provide a literal value, specify the following options.

Time Stamp Server URL:

Sets the URL for a TSP server. If no value is provided, the timestamp from the local system is applied. No default value is provided.

Time Stamp Server Username:

Sets the user name, if necessary, for accessing the TSP server. No default value is provided.

Time Stamp Server Password:

Sets the password for the user name, if necessary, for accessing the TSP server. No default value is provided.

Time Stamp Server Hash Algorithm:

Sets the hash algorithm used to digest the request sent to the timestamp provider. Select one of these values:

SHA1: (Default)

The Secure Hash Algorithm that has a 160-bit hash value.

SHA256:

The Secure Hash Algorithm that has a 256-bit hash value.

The Secure Hash Algorithm that has a 384-bit hash value.

SHA512:

The Secure Hash Algorithm that has a 512-bit hash value.

RIPEMD160:

The RACE Integrity Primitives Evaluation Message Digest that has a 160-bit message digest algorithm and is not FIPS-compliant.

Revocation Check Style:

Sets the revocation-checking style used for verifying the trust status of the CRL provider’s certificate from its observed revocation status. Select one of these values:

NoCheck:

Does not check for revocation.

BestEffort:

(Default) Checks for revocation of all certificates when possible.

CheckIfAvailable:

Checks for revocation of all certificates only when revocation information is available.

AlwaysCheck:

Checks for revocation of all certificates.

Use Expired Timestamps:

Select this option to use timestamps that have expired during the validation of the certificate. When this option is deselected, expired timestamps are not used. By default, this option is selected.

Predicted Time Stamp Token Size (In Bytes):

Sets the estimated size, in bytes, of the TSP response. The size is used to create a signature hole in the PDF document. This value represents the maximum size of the timestamp response that the configured TSP could return. Configuring an undersized value can cause the operation to fail; however, configuring an oversized value causes the size to be larger than necessary. It is recommended that this value is not modified unless the timestamp server requires a response size to be less than 4096 bytes. Valid values are from 60 to 10240 . The default value is 4096 .

Send Nonce:

Select this option to send a nonce with the request. A nonce is a parameter that varies with time. These parameters can be a timestamp, a visit counter on a web page, or a special marker. The parameter is intended to limit or prevent the unauthorized replay or reproduction of a file. When the option deselected, a nonce is not sent with the request. By default, the option is selected.
