SEGGER emCrypt

Overview

Designed with both efficiency and security in mind, emCrypt serves as a reliable encryption toolkit, offering all of the key components needed for today's secure protocols. In a world full of connected devices, keeping data secure is crucial. With emCrypt, users can trust that their embedded devices are protected against potential threats.

Key features

emCrypt includes various features designed to meet modern security needs, providing high-performance cryptographic solutions with a focus on clean and secure code.

Use cases emCrypt

offers versatile solutions for securing data in various scenarios. Whether safeguarding data during transmission with robust encryption protocols such as emSSL and emSSH, protecting sensitive information stored on devices using XTS-AES encryption, or ensuring data integrity through digital signatures, emCrypt provides comprehensive security against unauthorized access and data tampering.

Securing data in transmission

emCrypt ensures the protection of data during transmission through robust encryption protocols. Our solutions, such as emSSL and emSSH, use emCrypt's powerful encryption algorithms to secure communications over the internet, preventing unauthorized access and data breaches.

Securing data at rest

emCrypt provides robust encryption for data stored on devices, safeguarding sensitive information from unauthorized access. With our XTS-AES encryption technology, we ensure that data remains protected even if the physical device is compromised. This is essential for securing personal data, financial records, and confidential business information.

Ensuring data integrity

emCrypt uses digital signatures to verify that data comes from a trusted source and has not been tampered with. Using advanced cryptographic algorithms such as RSA, ECDSA, and EdDSA, emCrypt enables the creation and verification of digital signatures. This ensures that data remains tamper-free and authentic.

How emCrypt works

emCrypt offers a wide range of cryptographic capabilities which are the basis of many security protocols. It can be configured for the minimal memory footprint of constrained devices but can also scale to faster performance on systems that have more resources. A high-quality product, it is designed to be used with ease and without limitations. emCrypt has proven itself within SEGGER and is the foundation that emSSL, emSSH and emSecure-RSA, emSecure-ECDSA are built upon.

emCrypt offers several advanced features, including 

• An extensive 2,000-page manual that covers all API features and functions   
• Decoupled implementation ensures that only the necessary components are linked
• Public key cryptography with RSA, DSA, ECDSA, and EdDSA
• Fast, tunable ciphers, hash algorithms, and message authentication codes (MACs)
• Random bit generation and cryptographically secure pseudo-random numbers

Written in ANSI C, it is compiler- and target-independent. It can be implemented in PC applications and embedded systems.

End-to-end encryption

emCrypt provides a range of algorithms, functions, and cryptographic tools needed to implement different security schemes and protocols. It supports advanced protocols like emSSL (SSL and TLS) and emSSH, both of which are built on emCrypt.

For a deeper understanding of how to use emCrypt, explore our example applications. These examples demonstrate how to establish secure communication with end-to-end encryption and set up end-to-end encrypted communication between two clients without user interaction on a single, potentially insecure channel using ECDHE Key Agreement.

In use at SEGGER

emCrypt has proven itself within SEGGER and is the foundation of several security-related tools such as emSSL, emSSH, emSecure-RSA, and emSecure-ECDSA. All of these tools can be combined or used separately. 

emCrypt-BASE, emCrypt-PRO, and any additional emCrypt modules are only available upon request. Users receive emCrypt as source code, which provides transparency for all included modules and allows inspection by auditors. Written in ANSI C, it is compiler and target independent. It can be implemented in PC applications and embedded systems. Sample applications with source code are also available to demonstrate how to use the emCrypt API.

Free from an open-source or required-attribution license, emCrypt can be integrated into any free, commercial or proprietary product without the need to disclose the combined source. 

Pluggable cryptographic algorithms and hardware acceleration are supported by emCrypt. As an option, hardware acceleration for popular microcontrollers such as Kinetis CAU, STM32 CRYP, EFM32 CRYPTO, LPC18S and LPC43S is available.
