dug_seis.waveform_handler.utils module

Utility functionality for the waveform handler class.

dug_seis.waveform_handler.utils.compute_sha256_hash_for_file(filename: Path, max_bytes: Optional[int] = None) → str

Compute the sha256 hash for a file.

Parameters:

• filename – Path to the file.

• max_bytes – Only use the first X bytes if specified. Useful when hashing really large files and when it is reasonable to expect the the first few MB uniquely identify the file.
