Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based calculator for CRC-8 through CRC-82 checksums across text, files, and generated random data.

Landing page captured for the 2026-09-06 issue.

Field notes

The interface separates text, file, and random-input workflows, with history areas for text and file checksums. Random batches can be generated in six sizes from 10 to 500 entries and exported as CSV. The FAQ identifies several CRC families and compares CRC-8 variants by polynomial, initialization value, reflection behavior, and associated protocols; it also explicitly distinguishes error detection from cryptographic hashing.
