Now, pick your encryption method and save.
You can now open this disk image to use files as normal, but when you close the image it will be encrypted. Enter passwords for whatever options you choose, and save. As you may have noticed, Disk Utility gives you two options, and lets you know that choosing the more secure option is somewhat slower. This is a truism for all security matters — more secure is necessarily slower. You can choose from bit or bit AES. They will help make it more difficult to gather data from your files or folders, so that you can share or back them up with more peace of mind.

I think you may have had a similar issue that I had. I found that I needed to encrypt the document first rather than the folder and place the encrypted file s in a new folder, and then encrypt that new folder containing the encrypted file s. The you should have a password-protected folder that contains password-protected documents. This produced a disk image that I could put additional things into. That solved the problem for me.

If you click [Next] , VeraCrypt will begin walking you through the process of creating another encrypted volume. The steps below address the process of moving files from a TrueCrypt standard volume to a VeraCrypt standard volume that has already been mounted. In this section, you will learn how to create a Standard volume. SSL Encryption on the command line. Click [Next] and determine how large to make your encrypted volume. Next story.
