I have 7z on windows , and I want to encrypt 1 txt file with AES256 via 7z command line.
How can I do it please?
To make the answer simple just use the switch
-p which means Set Password with the default encryption which is
The example below will encrypt the file or folder and prompt for a password:
7z a -p Zip_File_Name File_2_zip.txt
The following example will auto add the password to the file for you.
7z a -pPassword Zip_File_Name.7z File_2_Zip.txt
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.
-pPASSWORD: setting the password
u: update existing archive with new or modified files.
-mx: default compression level (5/6) -
-mx1 (fastest) to
-mhe: encryption of file headers (encrypted file names).
