This tool calculates multiple CRC variants, including common CRC-8/16/32/64 algorithms, with flexible input/output formats.

Key Features

• Multiple algorithms (CRC-8, CRC-16, CRC-32, CRC-64)
• Text/Hex/Base64/File input modes
• Hex/Decimal/Binary output modes
• Optional all-algorithms result view

Steps

1. Select input format and provide data.
2. Choose CRC algorithm and output format.
3. Calculate and review result.
4. Expand all algorithms and copy results if needed.

Use Cases

• Protocol frame checksum validation
• File transfer integrity checks
• Embedded/industrial integration testing

Notes

• Different CRC parameters produce different outputs.
• Use exactly the same CRC specification as your protocol peer.
• CRC is for error detection, not encryption or signatures.
