Unregistered copies of CryptoSMS have a pass phrase size limit of three (3) characters, which isn't as secure as it could be.
CryptoSMS registration codes are free for all personal, non-commercial, and non-governmental uses.
These rego codes will remove all nag boxes, entitle you to future upgrades, and allow you to send secure short messages without any limitation on the length of your pass phrase.
To obtain your free registration code, just drop an email to our primary contact box:
Those wishing to run CryptoSMS for their commercial, law-enforcement, or governmental organisations, should request a quotation/invoice from our PayPal Billing Department:
When registering your copy of CryptoSMS, please be careful to provide your 8-digit SystemID number exactly as it appears in the CryptoSMS registration dialog. The registration code for your device can not be computed without it.
To see your CryptoSMS SystemID number, tap CryptoSMS > Register, and the rego box will appear:
It is also important that you include a valid destination, to which the registration code will be sent, either an email address or a mobile phone number.
Registration codes are computed daily, so you can expect to receive yours within 24 hours. When you provide a mobile phone number, your code will be sent by CryptoSMS and your registration will be instant, automatic, and very private.
Should you prefer to receive your code by email, just follow the directions contained in the registration message.
