Upload and share files safely into Dropbox

Cloud storage like Dropbox makes it easy for you to share files but at the same time puts you at risk of data leaks and security attacks. With Folder Cryptor, you can now persistently protect your precious files in Dropbox. Files you are uploading into secure folders are automatically encrypted before uploaded, so they are protected persistently and safely when in use, copied, moved, and shared with others.

Automatically encryption of files

When files are created in, copied into, or moved to a Folder Cryptor secure folder, they are automatically encrypted before uploaded.

Note : Setting an existing folder as a secure folder does not automatically encrypt files already existing in that folder. To encrypt those existing files, save them afresh. All files to be saved or copied after the setting will be automatically encrypted before uploaded.

Basic Secure Folder

When setting a folder as a secure folder through Folder Cryptor, you may set the folder as a Basic Secure Folder.

This Basic Secure Folder supports all kinds of file formats. Using the AES-256 encryption algorithm, files uploaded into a Basic Secure Folder are protected against unauthorized users and their access. The extension of files encrypted under a Basic Secure Folder is .fsb. The features of a Basic Secure Folder are as follows:

1. Automatically encrypts files uploaded into the Basic Secure Folder.

2. Gives members all permissions (for viewing/editing/decrypting) for the files.

3. Supports all kinds of file formats.

Advanced Secure Folder

When setting a folder as a secure folder through Folder Cryptor, you may set the folder as an Advanced Secure Folder.

This Advanced Secure Folder guarantees higher-level security than the Basic Secure Folder. If you share files in an Advanced Secure Folder, members can only view the files but cannot edit or decrypt them. The extension of files encrypted under an Advanced Secure Folder is .fsa. The features of an Advanced Secure Folder are as follows:

1. Automatically encrypts files uploaded into an Advanced Secure Folder.

2. Gives members a permission for viewing only for the files. The members cannot edit or decrypt the files.

3. Supports Microsoft Office file formats (docx, xlsx, and pptx), pdf, txt, jpg, png and bmp.

Share secure folders

Do you share files with friends, family, or colleagues through Dropbox? Then, do it safely with Folder Cryptor. It’s easy! Set your folder to share in Dropbox as a Folder Cryptor secure folder and share the folder as you normally do. Folder Cryptor will take charge of the security.

Windows

Mac

 

1.  Set a folder to share as a secure folder and share the folder through Dropbox.

- You can share your existing Folder Cryptor secure folder or firstly set a new folder as a Folder Cryptor secure folder and then share that folder. Members invited to that shared folder through Dropbox can access the files in the Folder Cryptor secure folder.

2. Set an existing shared folder in Dropbox as a secure folder.

- Do you share files with your colleagues through Dropbox? You can set an existing shared folder in Dropbox as a Folder Cryptor secure folder. The existing members of the shared Dropbox folder are automatically registered as members of the Folder Cryptor secure folder, so they can access the encrypted files in the secure folder. However, setting an existing folder as a secure folder does not automatically encrypt files already existing in that folder. To encrypt those existing files, save them afresh.

 

Automatically registration of Dropbox members

When a shared Dropbox folder is set as a Folder Cryptor secure folder, the existing members of the shared Dropbox folder are automatically registered as members of the Folder Cryptor secure folder. To invite members, invite them to the shared Dropbox folder. Then, they will be automatically registered as members of the secure folder.

To share a folder, right-click the folder and select Share this folder... in the Dropbox submenu list or share the folder on the Dropbox website.

1. Basic Secure Folder: Members will be granted all permissions.

2. Advanced Secure Folder: Members will be granted only a viewing permission.

For more details, refer to 04 Types of secure folders.

You can decrypt Folder Cryptor secure folders in your computer or files in those folders. Decrypting a secure folder means encrypted files in that folder are decrypted. In that case, the folder itself remains as a secure folder. The process of decryption is as follows:

Windows

 

Mac

 

1. Right-click a Folder Cryptor secure folder or a file in a Folder Cryptor secure folder.

2. Select Folder Cryptor > Decrypt Files...
