Crate affinidi_crypto 

Cryptographic primitives and JWK types for Affinidi TDK

This crate provides:

• JWK (JSON Web Key) types per RFC 7517
• Key generation for various curves (Ed25519, X25519, P-256, P-384, secp256k1)
• Key conversion utilities (e.g., Ed25519 → X25519)
• did:key encode/decode helpers for raw-bytes APIs (HPKE, ECDH) — see did_key
• Post-quantum signatures (FIPS 204 ML-DSA, FIPS 205 SLH-DSA) behind the post-quantum feature (off by default; also available individually as ml-dsa / slh-dsa)

Re-exports

pub use secp256k1::KeyPair as Secp256k1KeyPair;

Modules

bls12381
