Crypto Interface

TrustCore SDK Crypto Interface layer provides APIs for core cryptographic operations across multiple algorithms. By using these APIs, you can build applications that are independent of the underlying cryptographic implementation, allowing you to switch implementations based on export regulations, performance requirements, or certification needs without changing application code.

Key capabilities include:

• Support for multiple cryptographic implementations behind a consistent API layer
• Selection of cryptographic definitions at build time based on deployment requirements
• Control of runtime cryptographic behavior through build flags
• Flexibility to support both exportable and non-exportable product editions from a single codebase

For example:

• Build an exportable edition using non-restricted cryptographic definitions
• Build a certified edition using restricted cryptographic definitions that meet compliance requirements

Models

Crypto Interface is available in two models:

• Standard Edition
• Community Edition

For access to the Community Edition and related documentation, see the NanoCrypto repository.
