Quick File Hasher

A fast Linux alternative to IgorWare Hasher for streaming file checksum
calculation, expected-hash verification, HMAC-SHA256 string hashing, and
manifest validation. Independent open-source project, not affiliated with,
sponsored by, or endorsed by IgorWare.

FEATURES
• Single File & Direct Compare: Stream-compute MD5, SHA-1, SHA-256, SHA-512,
BLAKE2b, and CRC32 with real MB/s throughput measurement, UPPERCASE toggle,
one-click copy buttons, and a Paste Expected Checksum verifier that
auto-detects algorithm by length and highlights MATCH (green) or MISMATCH (red).
• Text / HMAC String Hasher & Folder Queue: Live UTF-8 string and HMAC-SHA256
/ HMAC-SHA512 hashing plus multi-file batch queue with export to .sha256,
.md5, .sfv, and CSV.
• Verify Manifest File: Load standard .sha256, .md5, .sha1, .sha512, or .sfv
checksum manifests and verify all referenced files on disk as OK, MISMATCH,
or MISSING.
