feat(bundle): add stream signing support for large files#2
Merged
Conversation
Add streaming hash and signing functions that process data incrementally without loading the entire payload into memory. This enables signing large files with constant memory usage and progress callbacks. New functions: - deep_hash_blob_stream: Stream-hash a blob - get_signature_data_stream: Compute signature hash with streaming data - sign_stream: Sign streaming data end-to-end Features: - 256 KiB default chunk size (matches Arweave) - Progress callbacks: on_progress(processed_bytes, total_bytes) - Produces identical signatures to in-memory sign() PE-8860 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
