Customizing signature workflows using seed values. Create the appearance of a certificate-based signature. Optional If you want to include an image of your handwritten signature in the certificate-based signature, scan your signature, and save it as an image file.
Place the image in a document by itself, and convert the document to PDF. When you sign, you select the signature by this name. Therefore, use a short, descriptive title.

Do one of the following:. Copyright Used with permission of Pearson Education, Inc. A digital signature, like a conventional handwritten signature, identifies the person signing a document.
Unlike a handwritten signature, however, a digital signature is difficult to forge because it contains encrypted information that is unique to the signer and easily verified. To sign a document, you must obtain a digital ID from a third-party provider or create a self-signed digital ID for yourself in Acrobat.
The digital ID contains a private key that is used to add the digital signature and a certificate that you share with those who need to validate your signature.

On rare occasions it is necessary to send out a strictly service related announcement. Create a System. Binding field. Cast the return value to BasicHttpBinding. Set the System. This value ensures that MTOM is used. Assign the corresponding password value to the field SignatureServiceClient. Assign the constant value HttpClientCredentialType. Basic to the field BasicHttpBindingSecurity. Assign the constant value BasicHttpSecurityMode.
Create a BLOB object by using its constructor. FileStream object by invoking its constructor and passing a string value that represents the file location of the PDF document to certify and the mode in which to open the file. Create a byte array that stores the content of the System. FileStream object. You can determine the size of the byte array by getting the System. Populate the byte array with stream data by invoking the System. A Boolean value that specifies whether to use the MDPPermissions object that was passed as the previous parameter value.
You can modify the appearance of the signature by setting one of its data members. A System. Boolean object that specifies whether the signature field is locked. That is, if you pass true to the previous parameter, then pass true to this parameter. FileStream object by invoking its constructor and passing a string value that represents the file location of the PDF document that will contain the certified PDF document and the mode in which to open the file.
Create a byte array that stores the content of the BLOB object that was returned by the certify method. BinaryWriter object by invoking its constructor and passing the System. Write the contents of the byte array to a PDF file by invoking the System. Adobe LiveCycle. Certifying PDF Documents. A certified signature is distinguished from a digital signature in these ways: It must be the first signature applied to the PDF document; that is, at the time the certified signature is applied, any other signature fields in the document must be unsigned.
Note: When certifying and signing the same PDF document, if the certify signature is not trusted, a yellow triangle appears next to the first sign signature when you open the PDF document in Acrobat or Adobe Reader. The certifying signature must be trusted to avoid this situation. However, you can set a configuration value, resulting in the sign or certify operation working without restarting the J2EE application server. Note: For more information about the Signature service and certifying a document, see Services Reference for LiveCycle.
Create a Signature client. Use certificates to encrypt documents and to verify a digital signature. A digital signature assures recipients that the document came from you. Encryption ensures that only the intended recipient can view the contents. A certificate stores the public key component of a digital ID. When you secure a PDF using a certificate, you specify the recipients and define the file access level for each recipient or group.
For example, you can allow one group to sign and fill forms and another to edit text or remove pages. You can choose certificates from your list of trusted identities, files on disk, LDAP server, or the Windows certificate store Windows only.
Always include your certificate in the recipient list so that you can open the document later. If possible, encrypt documents using certificates from third-party digital IDs. If the certificate is lost or stolen, the issuing authority can replace it. Alternatively, edit a sequence to add the security features you want. You can also save your certificate settings as a security policy and reuse it to encrypt PDFs.
From the Encryption Algorithm menu, choose a rate of encryption, and then click Next. The encryption algorithm and key size are version-specific. Recipients must have the corresponding version or later of Acrobat or Reader to decrypt and read the document. If you select bit AES, recipients must have Acrobat 7 or later or Reader 7 or later to open the document.
To set printing and editing restrictions for the document, select recipients from the list, and then click Permissions. To remove recipients, select one or more recipients, and then click Remove. Do not remove your own certificate unless you do not want access to the file using that certificate.
Businesses that use certificates for secure workflows often store certificates on a directory server that participants can search to expand their list of trusted identities. When you receive a certificate from someone, you can add it to your list of trusted identities. You can set your trust settings to trust all digital signatures and certified documents created with a specific certificate.
You can also import certificates from a certificate store, such as the Windows certificate store. A certificate store often contains numerous certificates issued by different certification authorities. Third-party security providers usually validate identities by using proprietary methods.
