Advanced cryptographic toolkit for Go providing primitives beyond basic signing and encryption for distributed systems.
Kyber is an advanced cryptographic library for Go that provides a toolbox of cryptographic primitives for applications needing more than basic signing and encryption. It enables developers to implement complex cryptographic protocols and distributed systems with support for various cryptographic suites and operations. The library includes both variable-time and constant-time implementations to address timing-based security concerns.
Go developers with moderate cryptographic knowledge who are building distributed systems, cryptographic protocols, or applications requiring advanced cryptographic operations beyond standard libraries. It's particularly relevant for projects like Cothority that need sophisticated crypto tooling.
Developers choose Kyber because it offers advanced cryptographic primitives not readily available in other Go libraries, with clean APIs that generalize across different group types. It provides more flexibility than basic crypto libraries while being more accessible than low-level implementations, making it suitable for prototyping and implementing complex cryptographic systems.
Advanced crypto library for the Go language
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a comprehensive set of primitives beyond basic crypto, enabling protocol development for distributed systems like Cothority, as highlighted in the README.
Supports multiple cryptographic suites including Ed25519, with both variable-time and constant-time implementations configurable via suites.RequireConstantTime().
Offers operations across different group types such as integer groups and elliptic curves, with clean APIs that generalize, making it versatile for various cryptographic needs.
Allows for shared secret derivation using (x, y) point marshaling, recommended for new software as it's cleaner and works across group types, though non-standard.
The library is offered as-is without warranties, and users must arrange independent security audits for production use, as stated in the README's reporting section.
Has experienced breaking changes between major versions, such as v4 introducing structural modifications that affect marshaling compatibility, requiring careful migration.
Targeted at developers with moderate cryptographic knowledge, making it less accessible for those unfamiliar with advanced crypto concepts or protocol design.
