よくある質問
MD5 vs SHA-256 — which should I use for checksums?
SHA-256 for security-sensitive verification. MD5 is faster for non-security checksums (data corruption detection) but vulnerable to collision attacks.
How do package managers use hashes?
npm, pip, and cargo store expected hashes in lock files. During install, they compute the downloaded package hash and compare — rejecting mismatches to prevent supply chain attacks.
