Crypto Interface

TrustCore SDK Crypto Interface layer provides a set of APIs corresponding to various cryptographic algorithms that application developers can use to perform core cryptographic operations. Use the Crypto Interface APIs to build applications that are agnostic to the underlying cryptographic implementation, which may use and link to different implementations depending on import/export restrictions, performance, or certification requirements. Appropriate core cryptographic definitions are linked, and the runtime usage can be controlled using build flags. This capability is useful for applications that require both exportable and non-exportable editions. For example, you can build one version as exportable with non-restricted cryptographic definitions, and another with restricted certified cryptographic definitions.
