Certify PDF operation

Input PDF

A document value that represents the PDF document to certify.

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 that are signed, it populates the Signature Field Name property as a list. The list contains fully qualified names of the signature fields in the PDF document. If the document is signed, an exception is thrown because a certification signature must be the first signature in the PDF document.

Certifying Credential

A Credential value that represents the security credential that is used to sign the PDF document.

If you provide a literal value, you can configure the following options.

Use SPI:

Select this option to use the credentials from the SPI. When this option is deselected, local credentials are used. By default, the option is deselected.

Alias:

Sets an alternative name for a credential managed by the Signature service. By default, a list of all signing credentials is provided. The list of credentials is comprised of Local and HSM credentials configured in Trust Store on the LiveCycle Server.

SPI Name:

Sets the name of the SPI that is provided to the Signature service. The SPI is used to extend the digital signatures functionality when credentials are not exposed to the LiveCycle Server. This option is available when the Use SPI option is selected. No default value is provided.

Certificate:

Sets the location of the certificate on the file system. No default value is provided. This option is available when the Use SPI option is selected. No default value is provided.

When you click the ellipsis button , the Open dialog box opens. In the dialog box, you can select a file from your computer or from a network location. During run time, if you selected a file from a location on your computer, it must exist in the same location on the LiveCycle Server.

SPI Properties:

Sets the location of the properties file to pass custom inputs to an implementation of the SPI. This option is available when the Use SPI option is selected. No default value is provided.

If you provide a literal value, clicking the ellipsis button opens the SPI properties dialog box. (See SPI Properties.) In the dialog box, add, remove, and edit the keys and values for each SPI property. The SPI implementation determines the keys that you provide. For information about creating custom service providers, see Programming with Adobe LiveCycle ES3.

Signature Field Name

(Optional) A string value that represents the name of the signature field in the PDF document that is signed. Before a PDF document can be signed, the signature field must exist, be unsigned, and have permissions for signing. The fully qualified name of the signature field is specified. If the signature field name is not specified, the Signature service adds an invisible signature field with an automatically generated name.

When using a PDF document based on a form created in Designer, the partial name of the signature field can also be used. For example, form1[0].#subform[1].SignatureField3[3] can be specified as SignatureField3[3]. If multiple signature fields exist with a similar partial name, the first signature field enumerated with the same partial name is signed. It is recommended that a fully qualified name is used to avoid these situations.

If you provide a literal value for the Signature Field Name property and a literal value is provided in the Input PDF property, a list appears. Select one of the values from the list of fully qualified names. Each fully qualified name represents a signature field in the provided PDF document.

Document MDP Permissions

(Optional) An MDPPermissions value that represents the permissions that control the actions an end user can perform on a document without making the certification signature invalid.

If you provide a literal value, select one of these values:

• No Changes Allowed: No changes to the document are permitted. Any change invalidates the signature.

• Form Fill-in and Digital Signatures: Permitted changes include filling in forms, instantiating page templates, and signing.

• Annotations, Form Fill-in, and Digital Signatures: Permitted changes include filling in forms and instantiating page templates, as well as creating, deleting, and modifying annotations.

Digest Hashing Algorithm

(Optional) A HashAlgorithm value that represents the hash algorithm that is used to digest the PDF document.

If a literal value is provided, select one of these values:

SHA1:

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

SHA256:

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

SHA384:

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.

Embed Revocation Information

(Optional) A boolean value that specifies whether revocation checking is performed for the signer's certificate. If revocation checking is done, it is embedded in the signature and then used during validation. It also enables the PDF file to be stored for long-term validation. A value of False means that revocation-checking is not performed and the values for the OCSP Options Spec property cannot be modified. The default value is True, which means that revocation checking is performed and the values for the OCSP Options Spec property can be modified.

If a literal value is provided, by default, the option is selected. When selected, it means that revocation checking is not performed and the values for the OCSP Options Spec property cannot be modified. When the option is deselected, it means that revocation checking is not performed and the values for the OCSP Options Spec property cannot be modified.

Lock Certifying Signature Field

(Optional) A boolean value that specifies whether the signature field is locked after it is used to certify the document. If the field is locked, the signature field cannot be modified or cleared without the certifying credential. The default setting is False, which means the signature field is not locked.

If the Process Documents With Acrobat 9 Compatibility service configuration property is selected, the signature field is locked. (See Signature service configuration.)

If a literal value is provided, by default, the option is selected. When selected, it means that the signature field is locked. When the option is deselected, it means that the signature fields are not locked.

Reason

(Optional) A string value that represents the reason for signing the PDF document.

If you provide a literal value, type a string or choose one of the following values:

• I am the author of this document

• I have reviewed this document

• I am approving this document

• I attest to the accuracy and integrity of this document

• I agree to the terms defined by the placement of my signature on this document

• I agree to the specified portions of this document

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:

• 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.

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.

RIPEMD160:

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

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.
