To make the answer simple just use the switch ( -p ) which means Set Password with the default encryption which is AES
example: 7z a -p Zip_File_Name File_2_zip.txt
7zip will encrypt the file or folder and prompt for a password.
or use
example 7z a -pPassword Zip_File_Name.7z File_2_Zip.txt
This example will auto add the password to the file for you.
The other switches used above are
7z a -p -mhe=on Zip_File_Name.7z File_2_Zip.txt
-pPassword == Auto add password without being prompted
-mhe=on == Means to encrypt the file names in archive too.

7za u -mx -mhe -pPASSWORD ARCHIVE-FILE-NAME.7Z SOURCE-FILE-SPEC
Any time you use the .7z format, the file is AES-256 encrypted.
Can you please explain me what is the arguments
u
andmx
andmhe

Is it documented somewhere? I can see that the -mem switch (EncryptionMethodID) is available for zip type. Documented here: https://sevenzip.osdn.jp/chm/cmdline/switches/method.htm - but the documentation does not say anything about the cipher used for other types. So how do you know?
