rust_cbor_cose_ecies

This Rust project demonstrates how to use CBOR, COSE, and ECIES in a single application.

Dependencies

  • ciborium: For CBOR serialization and deserialization.
  • cose: For COSE signing and encryption.
  • ecies: For ECIES encryption and decryption.
  • rand: For random number generation.
  • serde and serde_cbor: For serializing and deserializing Rust structs to and from CBOR.
  • rsa: For RSA key generation and signing.
  • sha2: For SHA-256 hashing.

Usage

  1. Clone the repository.
  2. Run cargo build to build the project.
  3. Run cargo run to execute the application.

Example Output

CBOR Data: [<...>]

COSE Data: [<...>]

Signature valid: true

Decrypted Data: [<...>]

Decoded Data: MyData { name: "example", value: 42 }

Explanation

  • The application first serializes a Rust struct to CBOR.
  • It then signs the CBOR data using COSE with RSA keys.
  • It verifies the signed COSE data.
  • It encrypts the CBOR data using ECIES and then decrypts it.
  • Finally, it deserializes the decrypted CBOR data back into the original Rust struct..
