It features a dual secure-processor hardware root of trust and supports easy integration via Python, C, and C++ APIs, making it ideal for professionals seeking robust, multi-layered device security. ## Description EASY TO INTEGRATE: Zymkey plugs directly onto the GPIO header of a Raspberry Pi making it quick and easy to install, even late in the design cycle. Software APIs are available in Python, C and C++. Example code and online documentation provide a simple low-risk way to integrate Zymkey security into your application running on standard Raspbian distributions. Support for other Linux distributions is optionally available. TOUGH TO INFILTRATE: Zymkey delivers multiple layers of security to protect against cyber and physical threats. A secure element (SE) with micro-grid protected silicon stores the most sensitive resources. A security supervisor isolates the SE from the host computer and provides additional functions of multi-factor identity/authentication for devices, and multisensor physical security. APPLICATIONS: SD Card Encryption: There are many reasons to encrypt the Root File System (RFS) on the Raspberry Pi, from keeping wifi credentials private to protecting proprietary software and sensitive data from cloning. Zymkey integrates seamlessly with dm-crypt & LUKS open standards. Review: Amazing little device that is easy to use! - Zymbit has gone out of their way with great software support for this device. There are C and Python library that work out of the box after the one-step software install. Compared to other raspberry pi hardware products i've bought, where the software experience is basically half-baked, the zymkey has excellent support. If you're a security professional like me that needs hardware secret key support and rock solid encryption this is a great device. Review: Needs better tutorial - Documentation needs "hello world" style examples to get users up and running with the device. Otherwise, it's harder than it needs to be and you'll waste time. ## Features - AWS Qualified Device: Zymkey delivers device-based security features that are easy to integrate with desertcart Web Services IoT - ENCRYPTED ROOT FILE SYSTEM: Provides a cryptographic engine featuring some of the strongest commercially available cipher functions to encrypt, sign and authenticate data. - SECURE KEY STORAGE AND GENERATION: Generates and stores key pairs in tamper resistant silicon to support a variety of secure services. - PHYSICAL TAMPER DETECTION: Monitors the physical environment for symptoms of physical tampering. - SECURE ELEMENT HARDWARE ROOT OF TRUST: Provides multiple layers of hardware security - Hard to penetrate dual secure-processor architecture. Secure microcontroller supervises device multifactor identity and isolates secure element from host. Hardware based cryptoengine and keystore. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Y5R5RXP | | Best Sellers Rank | #4,274 in Single Board Computers (Computers & Accessories) | | Customer Reviews | 4.5 4.5 out of 5 stars (13) | | Date First Available | September 20, 2019 | | Item Weight | 0.01 ounces | | Item model number | Zymkey 4i | | Manufacturer | Zymbit | | Product Dimensions | 1.54 x 0.59 x 0.36 inches | ## Product Details - **Brand:** Zymbit - **Operating System:** Linux - **UPC:** 860000510714 ## Images ![Zymkey 4i: Security Module for Raspberry Pi | Root File Encryption | Secure Key Storage | Physical Tamper Detection - Image 1](https://m.media-amazon.com/images/I/61269Tj9hXL.jpg) ![Zymkey 4i: Security Module for Raspberry Pi | Root File Encryption | Secure Key Storage | Physical Tamper Detection - Image 2](https://m.media-amazon.com/images/I/6167l52HfJL.jpg) ![Zymkey 4i: Security Module for Raspberry Pi | Root File Encryption | Secure Key Storage | Physical Tamper Detection - Image 3](https://m.media-amazon.com/images/I/61LQAYnRF4L.jpg) ![Zymkey 4i: Security Module for Raspberry Pi | Root File Encryption | Secure Key Storage | Physical Tamper Detection - Image 4](https://m.media-amazon.com/images/I/61rOufh8DrL.jpg) ![Zymkey 4i: Security Module for Raspberry Pi | Root File Encryption | Secure Key Storage | Physical Tamper Detection - Image 5](https://m.media-amazon.com/images/I/71D+6Ubk1uL.jpg) ## Questions & Answers **Q: How long does the battery last, and is this compatible with a PI Zero?** A: Using a high quality 3V CR1025 coincell battery such as the Panasonic CR-1025EL, LITHIUM MANGANESE DIOXIDE will have typical battery life of 2-3 years off power, 3-5 years with power. ZYMKEY is compatible with Raspberry Pi Zero. **Q: Is this compatible with the raspberry pi 4 model b? https://www.amazon.com/raspberry-model-2019-quad-bluetooth/dp/b07tc2bk1x/** A: Yes. **Q: Can this be used with openssl, for instance to store the private key for a root certificate authority?** A: The Zymkey doesn't store externally generated private keys. It comes populated with 3 private keys that are generated at the time of manufacture. If you take a look at the Zymbit Community you will see further explanation and a few use cases. Take a look here: https://community.zymbit.com/t/why-are-there-3-slots-for-keys/525 Also, in the community section, you can do a search for openssl and see some usage examples. Please feel free to reach out directly to support@zymbit.com with additional questions or requests. **Q: What is the battery for ? What happens when it dies ?** A: The battery is required to maintain the Real Time Clock and the perimeter detect circuits when the host power is removed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing little device that is easy to use! *by P***Y on July 21, 2020* Zymbit has gone out of their way with great software support for this device.
