 All generated hashes use the algorithm you specify (default: `sha256`). You can enable the "Prefixed Document Identifier" format (e.g., `sha256:abc123...`) for compliance with the [GraphQL over HTTP specification](https://github.com/graphql/graphql-over-http/blob/52d56fb36d51c17e08a920510a23bdc2f6a720be/spec/Appendix%20A%20--%20Persisted%20Documents.md#sha256-hex-document-identifier) by setting `includeAlgorithmPrefix: true`.
