Encrypto is a free, easy-to-use app that lets you encrypt files with AES-256 encryption and then send them to friends or coworkers. It works on both Mac and Windows, so you can send encrypted files without worrying whether the other person can open it or not.

Protect Files with AES-256 Encryption
Take any file or folder and add AES-256 encryption to it. Let Encrypto give you peace of mind when it comes to the security of your files when sending them.

Send Password Hints
Instead of relaying a password, include a unique, embedded password hint that only the recipient would be able to decipher.

Send Files Using OS X Sharing
Share encrypted files via Mail, AirDrop, or Messages, or even share them with third-party apps like Dropbox. However you usually share, Encrypto has you covered.

Or Save Them to Disk
With Encrypto, you can encrypt your files even if you don’t need to send them. You know, for file security on your hard drive. Just put your file through Encrypto and boom — it’s protected.

Encrypt and Decrypt on Both Mac and Windows
Share files with friends no matter their OS. You use a Mac, your friend uses Windows — you both can encrypt and send files to each other with Encrypto.

Nice for encrypting and de-crypting

If your goal is to install this application on every machine you wish to share an encrypted file with, then this is the app for you. However this application is very limited with is compatibility. For example, you are created a duplicate version of your desired file(s) with their own filetype and password, so if you want to view or modify those files on another machine you are forced to use their software in order to do this. I would not recommend this application for those of you who simply want a way to password protect your files, as the added hassle of going back through the originating app tends to get annoying really quick.

Great app for locking files behind passwords

This is a really well-polished and well-made program for encrypting and decrypting files, but there are a few features that are missing. It’d be great if there were a setting to optimize the encryption, so we can use more of our CPU to help encrypt the file and bring down encryption times. Additionally, it’d be awesome if there were a setting that let us decrypt our encrypted files with open-source software like OpenSSL.

Great cross platform encryption tool

Works very well, very fast, free! However, know that after you encrypt, your ORIGINAL file is still insecure
and will remain that way. You must save the encrypted version to see it on your hard drive and verify
that all is secure. Then, to be safe, I manually sent the file via email to a windows pal who will decrypt
in his enterprise envrionment without fear of others reading it.
When I have more time for testing, I’ll skip the extra step and send the encrypted file right from the
app. BTW, a reviewer said the app ‘wont tell you where the encrypted file is stored. First, put the
to be encrypted file in a folder. Encrypt from there. Save from the app. You’ll see the .crypto file
saved to your open finder window.
