Security tip: How to use encryption and digital signature. Simply put, encryption is a way to send information by password. Only the person with the correct key can unlock the password of this information. To others, this information looks like a series of random letters, numbers and symbols. Encryption is especially important if you want to send sensitive information that should not be seen by others. Because e-mail is sent on the Internet, it may be intercepted by attackers, so it is very important to add an extra layer of protection for sensitive information. Like digital signature, public key encryption uses software such as PGP, uses mathematical algorithm to transform information, and relies on public key and private key. However, there are differences between encryption and digital signature. The purpose of encryption is to secretly hide content by converting information into passwords. The purpose of digital signature is completeness and identification, verifying the sender of the message and indicating that the content has not been modified. Although encryption and digital signature can be used separately, you can also use digital signature for encrypted information. When you sign a message, you use your private key, and anyone can verify that the signature is legal with your public key. When you encrypt a message, you use this public key for the person who receives your message and use his or her private key to decode the message. In order to keep people's private keys secret and protect them with passwords, the recipient of this information should be the only one who can view it. 1. Get the public key of the person you want him to read this information. If you get this key from an open key ring, you can contact that person directly and use this key to verify that a series of related letters and numbers are correct fingerprints. Encrypt this email with their public key. Most e-mail client software has the ability to do this easily. When this person receives this information, he or she will be able to decrypt it.

The difference between digital signature and encryption is that encryption uses a key and a certain encryption algorithm to process the encrypted object; Only after decryption can the original text be obtained. Some are public keys and some are public algorithms. The decryption process is so complicated that the potential cracker gives up.

Digital signature is to ensure that the processed data will be identified if it is tampered with during transmission.

3. Click "Settings" on the side, enter the name of the security settings, and select your two files in "Certificates and Algorithms" to confirm.

4. If you can't find your certificate when you select your two files in the certificate and algorithm in step 3, please select Import and Export from Tools-Options-Secure Digital ID (Certificate), import from one file, confirm after importing the two files, and then proceed to step 1 to step 3.

I have been typing for a long time, hehe, I hope I can help you finish it.

Any questions? Hi. I

How to use digital signature? Digital signature is an electronic password composed of a series of symbols and codes generated by public key cryptography and other cryptographic algorithms, which is used to replace handwritten signatures and seals. This kind of electronic signature can also be technically verified, and its verification accuracy is incomparable with manual signature and physical drawings. This signature method can be used for authentication in a large number of trusted PKI domains or cross authentication in multiple trusted PKI domains, especially for security authentication and transmission on the Internet and WAN.
