Due to the recent revelations regarding the human rights privacy violations of the NSA, I am making this application free and will likely be open sourcing it when I have time. I hope you find it useful.


A simple app for encrypting and decrypting files and folders. Uses AES 256bit encryption in CBC mode and can securely shred old unencrypted files after they are encrypted. File format is open and can be decrypted on any platform using openssl and the user chosen password.

Internationalized for english, french, german and italian.

AES 256 bit encryption, decryption that is the BEST for OS X !

I have had crypt for two years, and when Apple Mac OS Mountain Lion came out, it was not compatible at first but within two weeks or so, the developer of this great app, had a fix for it, and I had a flexible, and one of the FEW…., MAC OS X, 256 bit AES, DOD, encryption, that you can drag and drop, a file or folder onto, the app, when launched. And any password, you choose, of course, be wise, use an 8 character alpha numeric at least, however, it can be any combination. The best part is, no-one can crack these 256 bit files with a good password on them, and you can even re-encrypt the file a second or third time, and so on. Whether it is audio, video, graphic, or text, etc, the file will becorrctly decrypted, and untouchable, by anyone. Just make sure you keep that password, backed up somewhere. For the low price, and flexibility and reliability I give this a 5 star rating.

No solution for 10.7

I have documents from prior version of the app, but that app no longer runs. I'm on 10.7.5 and, while this app requires 10.8, I saw no other option for accessing my encrypted files. I spent $7 and discovered it doesn't work either (crashes on app launch). I suppose I can update my OS (even though I don't want to) in order to unlock my documents, maybe that will work. If I do go that route, I will unlock the files, find a different encryption solution, and DELETE this app forever.

Simple. Works Like a Charm.

This app is super-simple. It encrypts your documents or folders. It does this very well. And it does it with a very nice, minimal UI. Kudos.
