Detailed Description / Procedure
The settings related to encryption types can be found in HENNGE Email DLP by logging in with an administrator account and navigating to the left menu [Encryption] - [Encryption Types].
Procedure

2. Fill in each field and select [Create].
Settings
1. Name
Enter any value.
* The name must be no more than 256 characters long.
2. Password Type
Select random password or fixed password for the ZIP encryption password.
- Random Password: A 16-character password is randomly generated, including uppercase letters, lowercase letters, numbers, and symbols. The number of characters cannot be changed.
* When selecting a random password, a checkbox for "Generate a different password for each recipient" will be displayed. Checking it will generate a different password for each recipient.
Can the policy for random passwords be changed?
- Fixed Password: A password set in a fixed format is used. When using a fixed password, a notification message will not be sent to the recipient.
- Password Format: Input becomes possible when selecting a fixed password. Set it within 60 characters using the following available characters.
- Alphabets: Uppercase and lowercase letters
- Numbers: 0123456789
- Symbols: `~!@#$%^&*()_+-={}|\[]:;'<>?,./" </>
- Tags for Merging:
- ((%YEAR%)): The year the email was sent is input.
- ((%MONTH%)): The month the email was sent is input.
- ((%DAY%)): The day the email was sent is input.
* The above items are obtained from the header information of the sent email.
The email header from Microsoft 365 includes Greenwich Mean Time, so the value is adjusted from Japanese time by -9:00.
- ((%LOCAL-YEAR%)): For the year the email was sent, the value is input according to the time zone in the general settings of the management screen.
- ((%LOCAL-MONTH%)): For the month the email was sent, the value is input according to the time zone in the general settings of the management screen.

- Simplified Chinese (CP936)
- Thai (CP874)
- UTF-8
4. Notifications
Check either "Notify Sender," "Notify Receiver," or both.
* When checking "Notify Sender," notification emails will be sent based on the notification text defined in "Notification (Sender)." Checking "Notify Receiver" allows you to select the notification text defined in "Notification Template," and notification emails will be sent based on the selected template.
* If nothing is selected, the notification text of the policy with the highest priority set in "Notification (Receiver)" will be automatically assigned.

If there are multiple attached files, the email source includes multiple headers with "Content-Disposition: attachment; filename=" each containing a different file name. The input will be the first file name displayed among them.

6. Non-Encrypted File Extensions
