CRC Checksum Integration

Overview

Use this skill to integrate CRCs and checksums by making the exact algorithm parameters explicit. Most CRC bugs come from two sides using the same name for different init, reflection, xorout, byte order, or covered range.

When To Use

Use this skill when:

• The user needs CRC-8, CRC-16, CRC-32, additive checksum, Fletcher, Adler, or protocol frame validation.
• The issue involves mismatched CRC values, boot image validation, Modbus, CAN, UART packets, storage records, or OTA packages.
• The target uses hardware CRC units, DMA, endian-sensitive protocols, or streaming updates.

Do not use this skill for cryptographic authentication. Use mbedtls-integration, tinycrypt-integration, or micro-ecc-integration when adversarial tampering matters.
