Step 1: User Authentication and Input
The script allows users to log in with their email credentials, typically using their email address and password. Once logged in, users can enter details such as the client name, test name, FID number, account manager email, client email, phone number, and a lock password. These details are necessary for composing the email message.

Step 2: Attaching and Encrypting Files
Users have the option to attach a file to the email. The script uses the provided lock password to encrypt the attached file before sending it. To achieve this, the script employs the pyzipper library, which creates a password-protected ZIP archive for encryption.

Step 3: Establishing SMTP Connection and Sending Email
The smtplib library is utilized to establish a connection with the SMTP server. In this case, the script connects to Gmail’s SMTP server. Once the connection is established, the email, including the encrypted attachment, is sent to the recipient(s). This step ensures the secure transmission of the email and attachment.

Step 4: Error Handling
In case of login or email sending failures, the script displays error messages using message boxes. This feature provides immediate feedback to users if any issues occur during the process.

Conclusion:
The script discussed in this blog post offers a convenient and secure method for users to send reports via email. By integrating user authentication, attachment encryption, and SMTP functionality, the script streamlines the process while ensuring data privacy and security. Organizations can leverage this script to facilitate the secure transmission of sensitive information, mitigating the risk of unauthorized access. With its user-friendly interface and error handling mechanisms, the script provides a reliable solution for sending encrypted email reports with attachments.
