Use this 技能 for Cryptowerk-backed proof 工作流s.

Supported primitives:

obtAIn a fresh 服务 凭证 register data using its SHA-256 哈希 and 接收 a retrieval id fetch a seal by retrieval id 验证 data agAInst a seal

Default style:

sidecar files for local 状态 no SDK dependency When to use

Use this 技能 when the user wants:

verifiable 记录s proof of existence Cryptowerk sealing retrieval IDs and seals stored locally deterministic local artifacts for later 审计 工作流 Register a file 哈希 with scripts/register.py Poll for a seal with scripts/获取seal.py 验证 with scripts/验证.py Requirements

python3

凭证 handling:

keep issued 令牌s out of watched or committed trees the 技能 uses 服务 凭证s only for the documented proof-APIs Quick 启动 Register a file Fetch a seal 验证 a file Local artifacts .cwseal Rules Use SHA-256 over exact raw bytes. Keep issued Cryptowerk 令牌s outside watched trees. Keep the seal and metadata in a sidecar file .cwseal . References
