Keep your incoming and outgoing messages totally secure.
Any time you send an SMS, e-mail, or iMessage™, it's like sending a postcard in that the message can potentially be read by any Internet user. Which means that all such messages are totally open, non-secured, and modifiable.
E-mails and text messages are particularly vulnerable in this regard, as they pass through numerous server node points on their way to their destination and can be read, copied and/or modified anywhere along the way. Thus your messages can be read by anyone, just like the messages on the back of a postcard.
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, WhatsApp™, iMessage™, Facebook™ or Twitter™. iCrypter™ also enables you to save encrypted texts to your clipboard for use in other messages.
Application examples
iCrypter™ can be used for confidential correspondence between and within:
- Large companies
- Domestic or foreign company divisions or sites
- Attorneys, tax consultants and clients
- Investment bankers
- Stock brokers and institutional investors
- M&A
-
iCrypter™ also supports encryption of photo, video and document attachments

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.
What's more, the iCrypter™ Contacts Tool is also protected
by 256 bit AES encryption against loss or unauthorized access.
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.
Moreover, the entirety of your data is deleted, along with all of your iCrypter™ apps settings, in such a way that they cannot be recovered, in accordance with military security standards such as the US Department of Defense's DoD 5220.22-M E method.
The deletion technology for this process is based on prize winning ProtectStar™ iShredder™ technology.
Communicate with everyone at any time
with confidence
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.
* iCrypter™ must be installed with both parties. Please use encryption for good.
Encrypting and/or transmitting illegal material is punishable by US and international laws.

No hidden fees
Unlike other encryption solutions that engage in practices such as charging per encrypted messages, with iCrypter™ you'll never have to pay a dime in additional fees.
Once you've download iCrypter™ from the AppStore, you can send as many secure messages as you wish and will only be charged your provider's regular fee as indicated in your cell phone contract.
