AWS AmazonS3 documentation change
Summary
Expanded the list of supported checksum algorithms in the metadata tables schema documentation to include MD5, XXHASH64, XXHASH3, XXHASH128, and SHA512.
Security assessment
This change adds documentation about additional checksum algorithms available for object integrity verification. While checksums are a security feature for data integrity, there's no evidence this change addresses a specific security vulnerability. It simply expands the list of supported algorithms.
