When using WPS text and Word text for daily office work, it is often necessary to produce various documents. When making a contract or writing an application, sometimes the applicant's signature needs to be handwritten, then When the applicant is not present, a handwritten name needs to be produced where the state instructs the applicant to sign. Since we are now in the digital age, even personal signatures often use electronic signatures instead of handwritten signatures.

The method of handwritten signature in the computer WPS electronic version is as follows:

1. Open the WPS document electronic contract file, click Insert-Picture,

2. Insert the handwritten signature After selecting the picture, click the picture layout option and set it to be placed below the text.

3. Move the picture to the appropriate position.

4. Click the picture, and then click above Picture tool, click Color,

5. Click to set to black and white,

6. This will set the handwritten signature item.

First open the Zen Brain and import the signature into a blank document; after the image is imported successfully, click the right button of the mouse and set it to float above the text; click Format in the toolbar, click Color, set the transparent color, and The version signature is set.

Introduction

To put it simply, the so-called digital signature is some data attached to the data unit, or the cryptographic transformation of the data unit . This data or transformation allows the recipient of the data unit to confirm the origin of the data unit and the integrity of the data unit and protect the data from forgery by someone (such as the recipient).

It is a method of signing messages in electronic form. A signed message can be transmitted in a communication network. Digital signatures can be obtained based on both public key cryptography and private key cryptography, mainly digital signatures based on public key cryptography. Including ordinary digital signatures and special digital signatures.

Common Hehuashu digital signature algorithms include RSA, ElGamal, Fiat-Shamir, Guillou-Quisquarter, Schnorr, Ong-Schnorr-Shamir digital signature algorithm, Des/DSA, elliptic curve digital signature algorithm and limited automatic Machine digital signature algorithm, etc.

Special digital signatures include blind signatures, proxy signatures, group signatures, non-repudiation signatures, fair blind signatures, threshold signatures, message recovery function signatures, etc., which are closely related to specific application environments.

Obviously, the application of digital signatures involves legal issues. The U.S. federal government has formulated its own Digital Signature Standard (DSS) based on the discrete logarithm problem in finite fields. Some countries such as France and Germany have enacted digital signature laws.
