craft_parts.sources.checksum module¶
Helpers to compute and verify file checksums.
- craft_parts.sources.checksum.split_checksum(source_checksum)[source]¶
Split the given source checksum into algorithm and hash.
- Parameters:
source_checksum (
str) – Source checksum in algorithm/hash format.- Return type:
tuple- Returns:
a tuple consisting of the algorithm and the hash.
- Raises:
ValueError – If the checksum is not in the expected format.
- craft_parts.sources.checksum.verify_checksum(source_checksum, checkfile)[source]¶
Verify that checkfile corresponds to the given source checksum.
- Parameters:
source_checksum (
str) – Source checksum in algorithm/hash format.checkfile (
Path) – The file to calculate the sum for with the algorithm defined in source_checksum.
- Return type:
tuple- Returns:
A tuple consisting of the algorithm and the hash.
- Raises:
ValueError – If source_checksum is not of the form algorithm/hash.
ChecksumMismatch – If checkfile does not match the expected hash calculated with the algorithm defined in source_checksum.
