## What is iCrypter?

***** All text messages, sms, emails, etc. are fully encrypted with AES-256 bit encryption algorithm.
***** ProtectStar™ apps are preferred by more than 1.000,000 users in 123 countries.

Thanks to iCrypter™, you can now convert your device into a highly secure message encryption device.

Impregnable encryption, military style
=======================
iCrypter™ is a small and extremely powerful encryption app that encrypts your confidential messages using the 256 bit AES (Advanced Encryption Standard) algorithm. This encryption technology is one of the most impregnable available today and is used to encrypt top secret government, industrial and military documents. 

The encryption process is carried out right in your device, and its symmetrical cryptography guarantees that your messages can be read solely by their intended recipients. 

With this app, you can ensure that all of your sensitive incoming and outgoing messages are impregnably secure, whether they be transmitted via e-mail, Facebook™ or Twitter™. iCrypter™ also enables you to save encrypted texts to your clipboard for use in other messages. 

A supremely user friendly app
===================
Despite its high tech security functions, iCrypter™ is incredibly easy to use, as it allows you to encrypt your messages in three easy steps: 

1. Write your message in iCrypter™ or paste an existing text into the application. 
2. Encrypt your message with a password. 
3. Send the encrypted message to one or more recipients. 

To post a confidential message on Facebook™ or Twitter™, just click the appropriate button. 

Thanks to iCrypter™’s intelligent hyperlink function, a message recipient need only click on an incoming message in order to read it. iCrypter™ then automatically opens and the decryption process begins automatically once the recipient has entered the correct password. 

iCrypter™ also supports the encryption of photo, video attachments
=========================================
iCrypter™ enables you to encrypt not only your e-mails and other messages, but also complete photos, video or document attachments. The app encrypts such items along with your message. This can be done for pictures and videos.

The iCrypter™ address book
==================
With iCrypter™, you can store encryption passwords together with the contact details for specific recipients in a separate iCrypter™ contacts tool, which functions independently of your Apple™ contacts. 

All data remains encrypted in the absence of authentication 
=====================================
iCrypter™ uses the practical and secure linear (4 x 4) password entry process, in lieu of conventional password protection. This technology enables you to protect your iCrypter™ application against unauthorized access. 

An automatic-delete function – just in case
===========================
In the event your Apple™ device is lost or stolen, you need not worry about your contacts and secret encryption passwords stored in iCrypter™ falling into unauthorized hands, because with the automatic-delete function activated the app can be configured so that all of your stored settings such as your bookmarks will be deleted automatically after five invalid passwords are entered. 

Twitter™, Facebook™ and the like
=====================
Besides text messages and e-mails, you can also use iCrypter™ to send secure twitter, Facebook™ and Skype™ messages. This allows for impregnably secure social-media interaction with friends or groups that have your secret password. 
contract.

### 1/5 — Does not work, Poorly constructed.

*2021-01-26, version 1.0.15*

Purchased this app yesterday and guess what it’s the most poorly constructed app I ever used. It was very inconvenient for the end user to download the app to decrypt a message or email, second most of its settings features does not work such as connecting to Facebook and so, it keep outputting an error and does not connect to Facebook. I am requesting a full refund and I won’t recommend this app to anyone.

### 1/5 — Crooks!

*2017-05-11*

Seems like all the creators of this app wanted to do is steal your money!

### 2/5 — Lame

*2015-10-15*

4th time attempting a review!! No wonder there are no reviews. I Want A Refund PLEASE! I mean it a good program but it's not user friendly and the other person has to pay for the app. I'm used to ios9 this runs more like aos circa 2010. I just want my data encrypted on my phone please

### 1/5 — Useless

*2015-01-11*

App doesn’t decrypt

### 1/5 — DOES NOT WORK AT ALL

*2014-09-23, version 1.0.12*

Worked great until recently. Now, when trying to open an encrypted message in email, the app either crashes or just opens a blank screen. It also crashes when trying to send very long text messages. Basically, as of this point, the app is pretty much useless.

### 2/5 — End user

*2014-08-14*

So when I see that I can send encrypted SMS I imagined that meant to everybody in my contacts. I was misled into believing that the receiver of my encrypted messages would be able to read them without this app on their phones. Wasted $3. You got me this time....

### 5/5 — Nice

*2014-06-08*

Amazing

### 1/5 — Terrible

*2014-06-07*

This doesn't even let you send messages

### 5/5 — ☺️

*2014-03-22*

يستحق الشراء

### 5/5 — Future is bright!

*2014-03-18*

GREAT APP.  Best in this category... I have most of them and this is my favorite.  Plus, I TRUST German developers.  They aren't required - under pressure - to relinquish the keys or make a back-door for US Government, state, or local government illegal "snooping".
