Crate provn_sdk 

Provncloud SDK

A high-performance, universal cryptographic engine for signing and verifying data claims.

This crate provides a lightweight, no_std compatible implementation for generating verifiable audit trails. It is designed to be compatible with resource-constrained environments like Solana programs and Arweave AO processes, while maintaining strict JCS (RFC 8785) compliance for cross-platform interoperability.

Structs

Claim

A Claim representing a statement of truth to be anchored. Fields are ordered alphabetically to ensure “Canonical JSON” (JCS - RFC 8785) compliance when using deterministic serialization.

SignedClaim

A SignedClaim wraps the claim with its signature and public key.

Enums

SdkError

Errors encountered during SDK operations.

Functions

compute_hash

Compute a SHA-256 hash of a byte slice for “Hash-Only” forensics.

generate_keypair

Generate a new random keypair

sign_claim

Sign a claim with a private key

verify_claim

Verify a signed claim
