Start your TheBat next! Select the "Select OpenPGP Version" command of the OpenPGP item in the Tools menu, as shown below: The "Select OpenPGP Execution" dialog box will appear, as shown below: After confirmation, select the "OpenPGP Key Manager" of the OpenPGP item of the Tools menu, as shown below: The "Key Generation Wizard" appears (if you are reinstalling the system and there is already a key in the restored PGP, then the PGP key manager will appear directly in this step. If you want to add a new key, you can select the "Keys" menu "New Key..." command under the command, otherwise, skip this step), select Next, the following picture will appear: Operate as shown, and then go to the next step: Generally speaking, the use of RSA algorithm is more common. It is recommended to choose the next step. Generally speaking, 2048-bit RSA is more secure... Next step: Next step: The longest password is 128 bits. As long as you can remember it, the longer the better, and It is best to use a mixture of letters and numbers. Pure numbers are not reliable as passwords. The password quality indicator bar in the middle clearly shows the length and security of your password. If your motherboard is not Intel's 810/815 series, before you click Next, you'd better be prepared to move the mouse. After clicking Next, you can start moving the mouse: ^_^ Now I finally know Intel Why is the hardware random number generator added to the firmware center (actually the BIOS) of the 8XX series motherboard chipset? Haha, after completion, click Next: Finally, Next: Completed, Haha, click "Finish", Look at the results: Wait:? ! Just back it up honestly... The public key doesn't matter, the private key below is your lifeblood: Okay, this most critical thing is done, there are a few parameters below to take a look at, open The Bat! The "OprePGP Parameter Selection" command of the OpenPGP item in the tool menu: a dialog box appears: OK, OK... But as we know, PGP is symmetric encryption. If someone wants to send you encrypted email, they must have your public address. The key will do. On the other hand, if you want to send encrypted emails to others, you must also have someone else’s public key. So how do you get someone else’s public key? As mentioned earlier, you can publish your public key to the server for others to query. You can also go to the server to find it yourself. The method is to start the PGP key manager (select the OpenPGP item in the Tools menu of The Bat! "OpenPGP Key Manager"), select the "Search..." command in the Server menu: Then the Search dialog box appears, select the appropriate conditions, search content, and then dial up to access the Internet, you can search: after you find the results you want , you can right-click on the result and select the "Import to Local Keyring" command to add the public key to your local keystore: However, the above public key for the public *** mailbox can of course be published to the server Yes, but what about private email? Of course it cannot be released, so you can only send it to others manually: Start the PGP Key Manager (select "OpenPGP Key Manager" of the OpenPGP item in the Tools menu of The Bat!), select the key you want to send, and right-click. Select "Copy", then "Paste" in the email content editing window (note, do not modify the pasted content) and send it to the other party (don't worry, your private key will not be posted^_^) : The delivery has been sent out, but what about the receipt? If you receive an email with a public key attached to someone else's content, you can directly choose The Bat! You can directly import his public key by using the "Enter OpenPGP key" command in the OpenPGP item of the Tools menu: At this point, the setting part is all over... Okay, everything is ready, let's give it a try : Write a letter according to the normal method. After writing it thoroughly (no need to change it again), select the "OpenPGP" item in the "Secret" menu of the email editing window, as shown below: After selecting one, a dialog box will appear: OK, OK, look at that letter now? Haha, it’s working, okay, let’s send it out... Well, it’s pretty fast. I received an encrypted letter, what should I do? Of course it is decrypted, haha, select the letter, and then select The Bat! Use the "OpenPGP Decode" command in the "OpenPGP" item of the Tools menu and enter your private key password. You will receive a PGPLOG dialog box telling you the result. If successful, you will find a message in your inbox. An email with the subject "(PGP Decrypted)" sent to and received by the same recipient as the original letter, of course decrypted... (If it is a signed email, it is the same as before, just then select "The Bat!" from the Tools menu OpenPGP" item's "Check OpenPGP signature" command instead of the "OpenPGP decode" command. The PGPLOG window will tell you the result. Of course, no decrypted email will appear): Hoo ho, it's finally over, ha ha, basically anyway PGP's mail functionality only goes so far.

Of course, PGP has many advanced functions, and PGP is not only used for email encryption, but can also be used to encrypt and decrypt text, pictures, other files, and even erase disks, etc. Please develop and expand these by yourself, hahahaha ^_^ Reference: /art/200512/14945.htm The website is rich in pictures and texts, and has detailed annotations, which is very suitable for beginners
