Protecting photos by password is one of the main
features of Hide Photos.
Data is encrypted using the AES algorithm with
256-bit keys. You can encrypt the entire storage, individual
photos, combine these two methods or use none of them.
Storage encryption. You can encrypt the
entire file-container, in this case, you will be prompted to enter
the password while opening the storage. Without knowing the
password it is impossible to open the storage. While creating the
storage, the program asks for a password. If you leave this field
empty, the storage will not be encrypted and you wouldn't have to
enter the password each time you open it. To password protect an
already created storage, you should open it and use the
"Storage-Change password" menu item. To remove password
protection, you should replace the current storage password with an
empty one -- simply do not fill the "New password" field.
Photo encryption. You can set password
for individual photos. You can also choose different passwords for
different photos. Instead of thumbnails for encrypted photos, a
green shield image will be displayed. To set password for the
selected photos, use the "Image-Change password" menu. To
remove password protection for photos, you should replace the
password with an empty one -- simply do not fill the "New password"
field. To quickly set a password for all photos in a folder, select
the folder and use the "Change password" menu item
Password hints. Since you can use
multiple encryption passwords simultaneously, Hide Photos allows
you to specify a password hint for each of the passwords. This hint
will be displayed after you have entered the password incorrectly a
few times. Do not set trivial hints -- it should remind the
password to you only and nobody else!
Set current password. The field for
entering the current password is located in the main program window
under the toolbar ("View with password"). The program attempts to
use this password to decrypt photos during various operations --
viewing, copying of images from the storage, rotation etc. If the
encrypted photo can be decrypted using the current password, its
thumbnail will have a small shield icon.
