Digitally signing a file is the process of using cryptography to prove a document’s authenticity and secure its contents. By digitally signing a file, you can ensure that no one else has tampered with it or changed its content in any way. This process also helps protect the identity of the signer, ensuring that only authorized individuals are legally binding documents. It’s an essential security measure for business owners, helping to ensure that sensitive documents can be securely shared and accessed without fear of them being corrupted or leaked.
