SSSS Mobile vs Tinfoil

SSSS Mobile is an implementation of Shamir's Secret Sharing Scheme (SSSS). In cryptography, Secret Sharing allows you to split a short "secret" text into multiple shares for later reconstruction when a specified threshold of shares are available. With SSSS Mobile, shares can be copied into another application or encoded in a QR Code and shared via email. Shares can later be retrieved from text, QR Code or NFC Tag (when available). You can also write shares to an NFC tag using a 3rd party NFC app. The optional Token parameter is prefixed to the share text to help describe the share or threshold. Some possible use cases for SSSS Mobile: * Split a short message intended for a group of individuals to decode only when the group is together. It may be interesting to store the shares on NFC tags attached to physical objects in this scenario. * Split an important but rarely used strong password across multiple QR Codes. Print and hide these QR codes in multiple locations for later retrieval. * Encrypt a large file with a difficult to remember password. Store the file in a potentially insecure location, but store the SSSS shares that protect your password in various other locations. Perhaps hide a large number of shares but only require a lower threshold for combination later if there is potential for some shares to be lost. * Encrypt the private key to your Bitcoin or other cryptocurrency holdings with an impossible to remember password. SSSS split the password, print the shares to QR Code and bury them in multiple locations. Require a lower threshold than the total number of hidden shares in case some are lost or damaged over time. IMPORTANT #1: If you intend to protect potentially important information, please take all necessary backup precautions and use at your own risk! IMPORTANT #2: The threshold must be met EXACTLY at the time of retrieval/combination. You cannot combine more or less than the exact threshold specified at the time that the share set is generated. It may be useful to use the optional Token parameter to indicate the threshold. Combining the wrong number of shares or invalid shares may result in an error OR an incorrect secret message reconstruction. IMPORTANT #3: The secret message must be 128 characters or less. The longer the message, the more processing time will be required for splitting and combining. For large secrets it is recommended to encrypt with a tool such as PGP/GPG and SSSS split only the password. Additional Notes: * This app uses the ssss-js library by Gabriel Burca to be compatible with the "ssss" UNIX/Linux application by B. Poettering.

An AI chat with verified privacy. The only way to protect your conversations is to make them inaccessible to anyone in the first place. Other AI applications ask you to trust them with your data, promising to anonymize them later or telling you they won't train on it. Tinfoil is built to prevent data leakage from the get-go. All our models run inside secure hardware enclaves that ensure your chats are private to you and invisible to everyone else, including Tinfoil. You can chat with state-of-the-art open-weight models without worrying about who else can see your conversations. THE HIGHLIGHTS • Your conversations are exclusively processed inside isolated, encrypted environments powered by NVIDIA confidential computing technology. Think of it as a digital vault that even Tinfoil can't unlock. It's the same hardware protection used for your iPhone biometrics, extended to cloud GPUs that run powerful large models and agents. • Every conversation starts with automatic enclave security verification. You can confirm that the app is connected to secure hardware running the correct AI model, isolating your conversation so that it is only between you and the intelligence on the other end. • You get the speed and features of the most powerful cloud-based AI services while getting the privacy equivalent of having a local model running on your phone. • All our privacy claims are backed by open-source code you can inspect, enabling public auditability and complete transparency. Visit https://github.com/tinfoilsh/ • Stop sharing your data with advertisers, model labs, and data brokers. Tinfoil keeps your conversations between you and the model, period. HOW IT WORKS Instead of trusting a privacy policy, you verify the protection yourself. Tinfoil's open-source inference software runs inside NVIDIA confidential computing enclaves, creating an encrypted sandbox that is cryptographically isolated from the rest of the cloud and the world. Every session begins with a security attestation you can inspect in the Verification Center, proving that the correct model is running and that nobody—not even Tinfoil—can peek inside it. You can read more about all the technical details in our documentation: https://docs.tinfoil.sh/verification/secure-enclave-primer In summary, you get: • End-to-end encryption and privacy from everyone, including Tinfoil. • The latest and most powerful open-source models. • Fully verifiable privacy through open-source code transparency, secure hardware, and public auditability.
