Digital Signature is an innovative method of creating an electronic signature that can be used for a variety of applications. It is based on the concept of digital signing, which refers to the process of sending a document to be signed, so that it can be verified by a third party. The electronic signature is created by using a cryptographic hash function and a private key. The private key is stored by the signer and the signer can use the public key to sign the document. The electronic signature is an essential tool for ensuring the authenticity of a document. It allows the signer to prove that the document was signed by the signer, and that the signer is the owner of the private key. It also allows the signer to prove that the document was signed at a specific time.
Digital Signature can be used to sign a document in a variety of formats, including PDF, Word, Excel, and PowerPoint. The resulting signature can be used in a variety of applications, including Microsoft Office, Google Docs, and Adobe Reader. It is compatible with Windows, Linux, Mac OS X, and Android.
