\"certificate<\/a><\/figure>\r\n\r\n\r\n

The company I work for happens to have to issue various certificates to many users, it would be very tiring if I had to input user names one by one. <\/p>\r\n\r\n\r\n\r\n

By generating the certificate directly through programming, we can send the certificate directly to the user’s email, without having to print and share <\/p>\r\n\r\n\r\n\r\n

Here is an example of a script that generates a certificate:<\/p>\r\n\r\n\r\n\r\n
