iscc-lib
High-performance Python bindings for ISO 24138:2024 -- International Standard Content Code (ISCC). Built on a Rust core for speed, with a Pythonic API that is a drop-in replacement for iscc-core.
What is ISCC
The ISCC is a similarity-preserving fingerprint and identifier for digital media assets. ISCCs are generated algorithmically from digital content, just like cryptographic hashes. However, instead of using a single cryptographic hash function to identify data only, the ISCC uses various algorithms to create a composite identifier that exhibits similarity-preserving properties (soft hash).
Installation
pip install iscc-lib
Quick Start
import iscc_lib as ic
result = ic.gen_meta_code_v0("ISCC Test Document!")
print(f"Meta-Code: {result['iscc']}")
