Provides standardized hashing for file fingerprinting, cache keys, and content-addressable storage. Example: from bengal.utils.hashing import hash_str, hash_file, hash_dict # Hash string content key = hash_str("hello world") # "b94d27b9..." # Hash with truncation (for fingerprints) fingerprint = hash_str("hello world", truncate=8) # "b94d27b9" # Hash file content file_hash = hash_file(Path("content/post.md")) # Hash dict deterministically config_hash = hash_dict({"key": "value", "nested": [1, 2, 3]}) Related Modules: bengal.cache.build_cache: Uses for file fingerprinting bengal.core.asset: Asset fingerprinting View source 5 Functions Functions hash_str Hash string content using specified algorithm. 3 str Caret Right def hash_str(content: str, truncate: int | None = None, algorithm: str = 'sha256') -> str Hash string content using specified algorithm. Parameters 3 Name Type Default Description content str — String content to hash truncate int | None None Truncate result to N characters (None = full hash) algorithm str 'sha256' Hash algorithm ('sha256', 'md5') Returns str — Hex digest of hash, optionally truncated hash_bytes Hash bytes content using specified algorithm. 3 str Caret Right def hash_bytes(content: bytes, truncate: int | None = None, algorithm: str = 'sha256') -> str Hash bytes content using specified algorithm. Parameters 3 Name Type Default Description content bytes — Bytes content to hash truncate int | None None Truncate result to N characters (None = full hash) algorithm str 'sha256' Hash algorithm ('sha256', 'md5') Returns str — Hex digest of hash, optionally truncated hash_dict Hash dictionary deterministically (sorted keys, string serialization). 3 str Caret Right def hash_dict(data: dict[str, Any], truncate: int | None = 16, algorithm: str = 'sha256') -> str Hash dictionary deterministically (sorted keys, string serialization). Parameters 3 Name Type Default Description data dict[str, Any] — Dictionary to hash truncate int | None 16 Truncate result to N characters (default: 16) algorithm str 'sha256' Hash algorithm ('sha256', 'md5') Returns str — Hex digest of hash hash_file Hash file content by streaming (memory-efficient for large files). 4 str Caret Right def hash_file(path: Path, truncate: int | None = None, algorithm: str = 'sha256', chunk_size: int = 8192) -> str Hash file content by streaming (memory-efficient for large files). Parameters 4 Name Type Default Description path Path — Path to file truncate int | None None Truncate result to N characters (None = full hash) algorithm str 'sha256' Hash algorithm ('sha256', 'md5') chunk_size int 8192 Read buffer size in bytes Returns str — Hex digest of file content hash hash_file_with_stat Hash file for fingerprinting (includes mtime for fast invalidation). Combines file content hash wi… 3 str Caret Right def hash_file_with_stat(path: Path, truncate: int | None = 8, algorithm: str = 'sha256') -> str Hash file for fingerprinting (includes mtime for fast invalidation). Combines file content hash with modification time for efficient cache invalidation without re-hashing unchanged files. Parameters 3 Name Type Default Description path Path — Path to file truncate int | None 8 Truncate result to N characters (default: 8 for URLs) algorithm str 'sha256' Hash algorithm Returns str — Fingerprint string suitable for URLs ← Previous file_lock Next → incremental_constants List © 2025 Bengal ᓚᘏᗢ window.BENGAL_LAZY_ASSETS = { tabulator: '/bengal/assets/js/tabulator.min.js', dataTable: '/bengal/assets/js/data-table.js', mermaidToolbar: '/bengal/assets/js/mermaid-toolbar.9de5abba.js', mermaidTheme: '/bengal/assets/js/mermaid-theme.344822c5.js', graphMinimap: '/bengal/assets/js/graph-minimap.cc7e42e3.js', graphContextual: '/bengal/assets/js/graph-contextual.440e59c6.js' }; window.BENGAL_ICONS = { close: '/bengal/assets/icons/close.911d4fe1.svg', enlarge: '/bengal/assets/icons/enlarge.652035e5.svg', copy: '/bengal/assets/icons/copy.3d56e945.svg', 'download-svg': '/bengal/assets/icons/download.04f07e1b.svg', 'download-png': '/bengal/assets/icons/image.c34dfd40.svg', 'zoom-in': '/bengal/assets/icons/zoom-in.237b4a83.svg', 'zoom-out': '/bengal/assets/icons/zoom-out.38857c77.svg', reset: '/bengal/assets/icons/reset.d26dba29.svg' }; Arrow Up X -------------------------------------------------------------------------------- Metadata: - Author: lbliii - Word Count: 1413 - Reading Time: 7 minutes
