Verifies an XML signature associated with
a signature field. After the verification occurs, an error occurs
to indicate that the document was signed in the future. The error
occurs because the signature, which is being verified, was applied
at a time that is more than 65 min. You can change this setting
in LiveCycle Administration Console. (See
Applications
and Services Administration Help
).
For example, your application requires that XML signatures are
validated on PDF forms. An XML signature signs the entire XDP package
for PDF forms created in Designer. You use the XML Signature operation
to validate that the signature validity of the signature and the
identity and trust chain of the signer.

Common properties
Properties to specify the input XML document and various
verification information.
Input XML
A
document
value
that represents an XML document that contains an XML signature to
verify.
If you provide a literal value, clicking the ellipsis
button opens the Select Asset dialog box. (See
About Select Asset
.)
When you provide a PDF document that
has signature fields, it populates the Signature Field Name property
as a list. The list contains a list of fully qualified names of
signature fields in the PDF document.
Signature Field Name
A
string
value
that represents the value of the ID attribute of the signature node
in the signed XML.
Revocation Check Style
A
RevocationCheckStyle
value that
specifies the revocation-checking style used for verifying the trust
status of the CRL provider’s certificate from its observed revocation
status.
If you provide a literal value, 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.
Verification Time
(Optional)
A
VerificationTime
value
that specifies the verification time to use. The default value is
Secure Time Else Current Time.
If you provide a literal value,
select one of these values:
-
Signing Time:
-
The time that the signature was applied as given by the signer's
computer.
-
Current Time:
-
The time that the verification operation is being carried
out.
-
Secure Time Else Current Time:
-
The time specified by a trusted time-stamping authority.
If
you specify Secure Time Else Current Time and validation returns
a status of unknown with a trusted timestamp, the validation is
checked using Current Time.
Advanced properties
Properties to specify path validation and other advanced settings.
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.
OCSP Options Spec

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:

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.
