You should encrypt your files to keep them safe from prying eyes. This is especially important when sending files to other Macs over untrusted email, instant messaging, and cloud-based services.
Scrambler is a simple, secure, and robust encryption app for the Mac. All you have to do is this:
1. Drag a file on Scrambler's icon in the menu bar
2. Type a password
3. Encrypt
To decrypt a scrambled file, just drag it back on Scrambler and type in the same password.
Other Features:
• You can also drag folders, or a collection of files and folders, on Scrambler — they will be encrypted into a single scrambled file
• The recipients of your scrambled files do not necessarily have to purchase Scrambler — they can download a free “decrypt-only” version of the app called Descrambler, also available on the Mac App Store
• You can configure Scrambler to automatically delete the original item(s) after encryption/decryption
• All icons, artwork, and user interface are fully compatible with the new retina display Macs
Technical Details:
• Uses industry-standard tar archiving and gzip compression
• Preserves OS X metadata of the original files, including extended attributes
• Uses 50,000 iterations of the industry-standard PBKDF2 key derivation function to generate the encryption key, which makes brute-force attacks on scrambled files practically impossible (unless the user chooses a weak password)
• Uses the secure industry-standard AES-256-CBC encryption algorithm
• Fully open and documented encrypted file format
• Scrambled files can, if desired, be decrypted in the OS X Terminal using free and open source command-line tools
• Runs in sandbox mode, a technology that vastly improves app security and is highly recommended by Apple for all Mac apps
v1.2
Scrambler 1.2.2:
• Fixes a bug where users with Macs running over network drives were not able to properly use the “source folder” feature.
• Fixes a bug where users could, in some cases, not properly select folders in the open dialog that appears before encryption/decryption.
Scrambler 1.2:
• A new, vastly more secure scrambled file format that makes brute-force attacks practically impossible (unless the user chooses a weak password).
• The new file format also produces more compact files—about 25% smaller.
• Adds the optional ability to automatically delete the original item(s) after encryption/decryption.
• A few minor improvements and bug fixes.
Important:
• Scrambled files created with Scrambler 1.2 will not decrypt on older versions.
• Descrambler users also have to upgrade to the newest version to decrypt the new file format. (Descrambler is a free “decrypt-only” version of Scrambler, also available on the Mac App Store.)
• The new versions are, of course, able to decrypt the old file format.
Scrambler 1.1.8:
• Sandbox support. This technology vastly improves app security and is now recommended by Apple for all Mac apps. For technical reasons, a consequence of this is that if you are currently using Scrambler’s “save in source folder” feature, you have to set it up again through Scrambler’s new Preferences window.
• Various minor improvements.
Scrambler 1.1.6:
• New icons and artwork that are compatible with the retina display.
• Fixes a bug that in some cases caused an error during decryption.
• Various underlying bug fixes.
Scrambler 1.1.4:
• Fixes a bug that in some cases caused an error/crash when encrypting folders.
Scrambler 1.1.2:
• Fixes a bug that made it unable for some users to launch the app.
• Some minor internal improvements.
Scrambler 1.1:
• The file size limitation of 250 MB has been removed; users can now encrypt as large files as they want.
• Adds a progress indicator that shows the percentage completion of the encryption/decryption.
• Encryption and decryption can now be cancelled during progress.
• Encryption and decryption are now dramatically more memory-efficient.
• Fixes a bug that sometimes, in rare cases, made it impossible to decrypt scrambled files.
• Fixes various other minor bugs.
• The underlying codebase has been completely reworked to take full advantage of new technologies provided in OS X Lion. For the user, this results in a nice performance boost. For the developer, this provides a great foundation for further improvements.
Scrambler 1.0:
• Initial release.
