> Maven Wrapper is downloading binary artifacts that are later executed. To prevent from an attack where a vulnerable repository could distribute malicious Maven (wrapper) artifacts, the downloaded artifacts should be verified against a secure checksum. If the expected checksum does not match, execution could be aborted before the potentially compromised artifact is executed.
> In my PR, i chose SHA-256 as it is cheaper to compute than SHA-512 but still impossible to replicate with a corrupted binary.
