Hash Enricher#
Module type
Generates cryptographic hashes for media files to ensure data integrity and authenticity.
Features#
Calculates cryptographic hashes (SHA-256 or SHA3-512) for media files stored in
Metadataobjects.Ensures content authenticity, integrity validation, and duplicate identification.
Efficiently processes large files by reading file bytes in configurable chunk sizes.
Supports dynamic configuration of hash algorithms and chunk sizes.
Updates media metadata with the computed hash value in the format
<algorithm>:<hash>.
Notes#
Default hash algorithm is SHA-256, but SHA3-512 is also supported.
Chunk size defaults to 16 MB but can be adjusted based on memory requirements.
Useful for workflows requiring hash-based content validation or deduplication.
