How to open SIG file

SIG is an extension for a digital signature document that stands for "Signature". The purpose of the signature is to confirm the file's authenticity or protect a copyright. SIG files tend to be attached to an archive with an e-mail or are located in a directory with software installation files.

Unique features

A SIG file is a digital signature text file or a raster image.

A SIG text file contains:

  • The sender and recipient's addresses (if the SIG signature is attached to a file with a downloaded message).
  • An encoded public key that verifies a message's integrity and, thus, authenticity.
  • The sender's name.

If the operating system recognizes the SIG extension as a graphic file, it means that the document belongs to a group of software products from the developer Broderbund, such as The Print Shop, The Print View, or PrintMaster.

A raster graphic with a SIG extension contains an image that is itself a digital signature for posters, covers, brochures, and other types of graphics documents from the software.
