CRC-64/ECMA-182 Calculator

Calculate CRC-64/ECMA-182

Calculate CRC-64/ECMA-182 from text. The output is a 16-character hexadecimal checksum.

CRC-64 variants are wider than CRC-32, but the exact profile still matters. ECMA-182 uses polynomial 0x42F0E1EBA9EA3693 with no reflection and no final XOR.

Fixed-width output

The calculator pads CRC-64 values to 16 hexadecimal characters. Leading zeroes are part of the fixed-width representation.

Frequently Asked Questions
