eSigner DocSignTool Command Guide

DocSignTool is a secure, privacy-oriented multi-platform Java command line utility for remotely signing PDF files using eSigner document signing certificates. Hashes of the documents are sent to SSL.com for signing so that the document itself is not sent. This is ideal where sensitive documents need to be signed, but should not be sent over the wire for signing. DocSignTool is also ideal for automated batch processes for high volume signings or integration into existing document workflows.

If you’d like to try DocSignTool with a demo account and certificate, please read eSigner Demo Credentials and Certificates for credentials and configuration information.

If you are looking to use esigner to sign code and excutables instead, please refer to this CodeSignTool guide.

OTP authorization is not required when signing using an esealing document signing certificate. Ignore all OTP parameters in the following guide if using an esealing document signing cerificate. (Customers with an existing Organization Validation document signing certificate can contact support@ssl.com to have it converted to an eSealing certificate.)

DocSignTool Installation

To install the current version of DocSignTool, simply download and unzip the correct file for your OS:

Note that the Windows download includes Java runtime, but the Linux/macOS version requires Java runtime to be installed on your computer. The Windows version of the command is a batch file (DocSignTool.bat) and the Linux/macOS version is a shell script (DocSignTool.sh).

Sign and timestamp PDF file. Parameters -username, -password, and -input_file_path are required. -credential_id is required only for users with more than one eSigner document signing certificate. -output_dir_path, -signing_location, -signing-reason, -contact_info-sig_field_position, -page_no, and -totp_secret are optional.

Usage: DocSignTool sign [-hV] [-credential_id=<CREDENTIAL_ID>] -username=<USERNAME> -password=<PASSWORD> -input_file_path=<PATH> [-output_dir_path=<PATH>] [-signing_location=<SIGNING_LOCATION>] [-signing_reason=<SIGNING_REASON>] [-contact_info=<CONTACT_INFO>] [-sig_field_position=<X, Y, WIDTH, HEIGHT>][-page_no=<PAGE_NUMBER>] [-totp_secret=<TOTP_SECRET>]

Optional parameters:

  • If -credential_id is omitted and the user has only one eSigner document signing certificate, DocSignTool will default to that. If the user has more than one document signing certificate, this parameter is mandatory.
  • If -output_dir_path is omitted, the file specified in -input_file_path will be overwritten with the signed file. DocSignTool will prompt the user before overwriting the file.
  • If -signing_location is present, the location specified will be added to the digital signature.
  • If -signing_reason is present, the reason for signing specified will be added to the digital signature.
  • If -contact_info is present, the specified text will be added to the digital sigature. Although included with the signature, this information will not be included in the visible signature annotation (if present).
  • If -sig_field_position is present, a visible signature annotation will be added to the document on the page specified by -page_no. The position and signature should be supplied in the format "x, y, width, height".
  • -page_no is only required when creating a visible signature with -sig_field_position and specifies the page of the document that the visible signature annotation will appear on.
  • If -totp_secret is present, DocSignTool will calculate a time-based OTP for signing, allowing automated use of the tool. If this parameter is not present, the user will be prompted for manual OTP entry.
For information on enrolling an EV document signing certificate in eSigner and setting up two-factor authentication, please read Remote EV Code Signing with eSigner. For information on the TOTP secret value, please refer to Automate eSigner EV Code Signing.

If you get the error message, Error: invalid otp when attempting to sign a file, it could be caused by one or more of these issues:

  • The QR code you scanned into your authentication app doesn’t match the username, password, and/or credential ID from your command. This could happen if:
    • You have multiple accounts configured for 2FA on your device and chose the wrong one.
    • You are attempting to use your login credentials for a shared certificate, but scanned a QR code shared by a teammate from their account.
  • The OTP you entered has already expired.
  • Your command includes an invalid TOTP secret.

hash

SHA 256 algorithm should be used to compute the hash of the PDF document. 

  1. A PDF library is needed to manipulate the PDF for hash input and later embed the PKCS#7 in the PDF document. (ex. ApachePDFBox in Java). 
  2. A Crypto library for creating PKCS#7 out of raw signatures received from eSigner API (ex. BouncyCastle in Java).

Pre-compute hash(es) for later use with batch_hash_sign command. Parameters -access_token and -input_dir_path are required. -credential_id is required only for users with more than one eSigner document signing certificate. -signing_location, -signing-reason, -contact_info-sig_field_position, and -page_no, are optional.

Optional parameters:

  • If -program_name is present when signing an MSI installer, the value will be displayed in the confirmation dialog as the program name.
  • If -signing_location is present, the location specified will be added to the digital signatures when they are generated.
  • If -signing_reason is present, the reason for signing specified will be added to the digital signatures when they are generated.
  • If -contact_info is present, the specified text will be added to the digital sigatures when they are generated. Although included with the signature, this information will not be included in the visible signature annotations (if present).
  • If -sig_field_position is present, a visible signature annotation will be added to the documents on the page specified by -page_no when the signatures are generated. The position and signature should be supplied in the format "x, y, width, height".
  • -page_no is only required when creating a visible signature with -sig_field_position and specifies the page of the documents that the visible signature annotations will appear on when they are generated.

How to test  DocSignTool in sandbox mode

  1. In the DocSignTool release, go to conf folder and open doc_sign_tool.properties file
  2. Comment out the existing properties by adding # symbol before every property
  3. Add the following properties in the file:
  4. Save the file. After saving, DocSignTool can now be used in sandbox mode.
  5. To switch back to production mode, uncomment the existing properties and delete the sandbox properties.

Optional: Convert your OV document signing certificate  to an esealing certificate

Note: This section is only for users who want to do esealing. To automate document signing and not be prompted by One Time Passwords (OTP), users self-convert their Organization Validation (OV) document signing certificate to an esealing certificate on their SSL.com accounts. Instructions are below:

  1. Click Orders on the top menu of your SSL.com account. 
  2. Locate your certificate and click the download/details link.
  3. Click the REMOVE 2FA button.
