Secure SMS Communications

This superb easy to install and use encryption software ensures that your SMS communications can be kept absolutely secure from prying eyes. Works on most BlackBerry, Android, Windows Mobile, Nokia, Sony Ericsson and Samsung handsets.

Due to the ease with which it is possible to eavesdrop on mobile phone communications today, this CrypToGo SMS encryption software has been developed for use on Nokia S40, Symbian OS 3rd edition, BlackBerry OS (4.6+), Android OS (2.1+), Windows Phone 7, Sony Ericsson and Samsung mobile phones.

This reasonably-priced, simple to use, but extremely secure encrypted SMS software is the ideal solution for keeping your communications secure.

The Advanced Encryption Standard (AES) specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information. Encryption converts data to an unintelligible form called ciphertext; decrypting the ciphertext converts the data back into its original form, called plaintext.

CrypToGo is an application written in J2ME and all of the cryptographic algorithms and implementations are taken from the highly reliable library called ‘Bouncycastle’. The system employs Elliptical Curve Cryptography (ECC) based on a 192-bit prime. In layman terms, this simply means that the software provides a very high level of security that really is more than sufficient for secure communications.

This system can only operate if there are two handsets that have the system installed and have been paired by an encryption key. The CrypToGo application operates its own user address book, so that only selected / paired users can send secure SMS messages between handsets. Each time you pair with another selected CrypToGo system user, a fresh encryption code is generated that pairs the two handsets to each other and this encryption code is then used to encrypt / decrypt SMS communication between these two handsets only.

Once installed there are no hidden fees, subscriptions or ongoing costs to keep the system live. This system is ideally suited for use by lawyers, Police and government personnel, politicians, executives, VIP’s and in fact anyone who recognises the need for complete secure SMS communication.

  • 100% totally secure SMS communication
  • Incredibly high level encryption algorithm
  • No hidden ongoing costs, fees or subscriptions after initial activation
  • Simple to install and very easy to use
  • Application is password protected on handset for additional security
  • Works on Symbian 3rd Edition, Nokia S40, Blackberry OS (4.6+), Android OS (2.1+), Windows Phone 7, Sony Ericsson and Samsung mobile phones. (iPhone coming soon)
  • Fully evaluated and approved by Department of Computer Science, Israel


If I put the software on my phone could I then communicate securely by SMS with anybody?

No, the software creates a whole new method of sending SMS messages via encrypted data and as such phone book entries on this system are only created for others who also have the same secure software with whom you have paired.

Can the software licence be transferred from handset to handset?

No, this is not possible. Once the licence has been used installing to a particular device then it is not possible to move it to another phone.

Can images or video be sent via this secure SMS method?

No, the system will only allow the creation and sending of short SMS text messages.


You will need to consider the following to use this product:

  • This system requires that more than one handset runs the CrypToGo application in order that handsets can be paired using a unique encryption key.
  • This application has multi-lingual support for both the User Interface and input language (supported languages - English, Spanish, Portuguese, Italian, German, French and Russian).
  • No Physical product is sent out to the purchaser. The licence key and instructions together with accreditations are sent by email to the customer.
  • Some mobile phone technical knowledge will be required to successfully install the softare. It may also be advantageous for the phone to be unlocked for any network in case another network SIM needs to be used to complete the initail subscription process.
