Crypten : Encryption for Android

By DynamiteChetan Free

Developer's Description

Using Crypten you can encrypt anything on your mobile device.This encryption app offers a comfortable and secure way to keep files with confidential data encrypted using most secure encrypting and hashing algorithms.

Using latest material design principles, this app gives you a easy way to keep your files secret and secure.

You can encrypt your files with a Text Based Password or select a File as password.

Text messages are encrypted using AES algorithm which is protected by a password. These encrypted messages can be sent to all your favorite messaging apps and social networks. You can send secret information like bank account numbers, license information etc to any person very safely. Even if somebody reads the message, he will not get anything out of it because after encryption its absolutely safe.

Top Features

All file formats including all images and video formats are supported.Also .pdf, .apk, .xps and others works very smoothly in the app

Same file produces different encrypted outputs every time. This is attained with a random initialization vector (IV) stored within the encrypted file.

Files are encrypted/decrypted on-the-fly, so content is overwritten.

When decrypting, if password is not the one used for encrypting, the process is aborted.

Very secure KECCAK-512 hashes are used

Encrypted files are appended the by a unique extension so that they can recognized only from the app.

Password can be obtained from keyboard or from a file

Binary files can be used as passwords: for example jpg images, etc.

Caution: do not lose this 'password' file and do not modify it!

Files bigger than 2 GB can be easily used with the app

Speed is extremely high: the app uses a native OS library and CHACHA20 is a very fast encryption algorithm.


Only Storage permission is required which is used to read and write files to your phone's storage.


Sometimes because of less memory in the phone app stops as it fails to load the file. But trying second time solves the problem.

If password lost then file cannot be recovered.

For any issue use the contact button in app. We will respond you within 2 days.
