Counterseal 4+

Get on the path to Internet privacy and independence with our crypto applications. They are end-to-end encrypted, anonymizable and require no account sign-up or log-in.

This Counterseal app is the most recent mobile suite Ai-Fi.net has developed. It emphasizes the "crypto" aspect of our privacy-centric end-to-end-encrypted network infrastructure. The PrivateMail allows everyone to email securely and privately but maintains the most critical federation aspect of the emailing without forcing users to sign up for a new email account . The CryptoSign utilizes the PrivateMail as a transport for conducting contract negotiations through emails the old fashioned way but supporting strong digital signatures and multi-party multi-factor authentication. They are both self-managed, provider-less and account-less, a far cry from most other popular electronic signature applications (e.g. DocuSign). The PlexiWallet, offers an alternative to hardware cryptocurrency wallets, fortified by the powerful Threshold Signature technology utilizing at least two air-gapped redundant devices to ward off cyber attacks or recover from loss of hardware. The CryptoVault is a simple password safe. All these mobile apps are collected in a single package due to their sharing of the foundational services implemented in the Crypton framework for provider-less and account-less self-managed cloud storage, including the SSS (Shamir's Secret Sharing) scheme for more protection options.


The Ai-Fi end-to-end encryption is no ordinary OpenPGP/S-MIME based, highly vulnerable, and in many cases provenly broken scheme. It deploys the latest signal.org double-ratchet algorithm with full forward and future secrecy (please visit our web site for the mouthful). It is warrant-proof, collecting no metadata, anonymizable and not requiring you to change your mailboxes. Our Counterseal mobile app would not have been able to achieve total privacy protection without making use of the latest Blockchain technology. This treasure trove of software is a demonstration of how we can navigate the Internet without relying on those behemoth public platforms like Google or Facebook and being swallowed up by the cogs of the Surveillance Capitalism. We at Ai-Fi.net are focusing on a “privacy” first approach and dedicating our efforts to “invert the Internet” for building a foundation for “Humane Technology”. For those looking for a good account of where we are coming from, we suggest you visit our ai-fi.net and counterseal.net websites.


Privacy is a means to independence in all aspects of our life, but not an end in itself. Privacy protection also has huge practical and financial implications in many important business activities. The privacy and confidentiality in business dealings such as the negotiation of merger and acquisition, price biddings of goods and services, intellectual property transfer, technology outsourcing and many others pose severe challenges when an e-signature service provider is involved. Positioned smack in the middle of the contract negotiation and being in on all the discussions and transitions, the e-signature service provider in those situations creates a most obvious MITM (man in the middle) risk. The Counterseal framework suggests a paradigm shift in conducting personal and business transactions without trusting service providers. The Counterseal CryptoSign application is a demonstration on how privacy protection can be correctly designed for the multi-billion dollar industry of e-contracting without employing a service provider like DocuSign.


Download and explore the various useful functions offered in this package. As previously mentioned, many included functions utilize the Blockchain (Stellar Network) for trustless and service-provider-free foundational supports, which do cost Lumens (cryptocurrency or fees). Designed carefully without requiring a payment account, the operational cost is either partially paid for when this app is first purchased or incurred on the pay-as-you-go basis when conducting your Counterseal operations.
