With Bouncy Castle C# .NET 2.5.0, developers gain access to the latest cryptographic tools, enabling them to address emerging security challenges, future-proof their systems, and cater to specialized use cases in light-weight cryptography for IoT, post-quantum security, and password management.
This release continues our commitment to innovation, empowering developers to build secure, scalable, and standards-compliant applications.
Highlights
Support for NIST Post-Quantum Cryptography (PQC) Standards
This release introduces support for the newly standardized NIST PQC algorithms, including:
It also supports signature context strings, enabling expanded applications for secure encryption and authentication. These advancements empower developers to begin migrating from classical algorithms to quantum-resistant alternatives, ensuring long-term security for encryption and digital signatures.
Updated Support for Ascon Algorithms
In alignment with the draft NIST SP 800-232 standard for Lightweight Cryptography, the Ascon family of algorithms in Bouncy Castle C# .NET has been updated. Ascon provides primitives for encryption, authentication, and integrity, optimized for use in IoT and embedded systems. This update is essential for developers and engineers working with constrained devices, where lightweight cryptography is necessary.
Argon2 PBE Algorithm Support
The release now includes the Argon2 Password-Based Encryption (PBE) algorithm, the winner of the Password Hashing Competition. Argon2 is a memory-hard algorithm designed to protect against modern attacks on older PBE mechanisms, ensuring stronger security for password-based encryption.
For developers needing secure password-based key generation for applications, Argon2 PBE provides a superior security alternative to traditional PBE mechanisms, safeguarding sensitive data from advanced threats.
