JavaCRC

JavaCRC is a parameterized checksum and CRC calculation tool, which supports many different algorithms and parameters. It is pre-configured with:

• 8-bit checksum
• 16-bit checksum
• 32-bit checksum
• CRC-16
• CRC-16 Modbus
• CRC-16 CCITT
• CRC-16 CCITT (0x1D0F)
• CRC-16 CCITT (Kermit)
• CRC-16 CCITT (XModem)
• CRC-16 DNP
• CRC-32

Maven configuration

	<dependency>
		<groupId>net.digger</groupId>
		<artifactId>crc-util</artifactId>
		<version>1.0.0</version>
	</dependency>

Usage

TL;DR: Give it a configuration and a message, get back a number.

• Can be called statically, for simple occasional use:

    String message = "...";
    long result = CRC.calculate(CRC.CRC16, message);
  

• For more intensive use, it's faster to create an instance and use the table-driven method:

    CRC<CRCConfig, CRCComputer> crc = new CRC<>(CRC.CRC16);
    String message = "...";
    long result = crc.calculate(message);
  

• You can also calculate the CRC incrementally:

    String message = "...";
    Long result = null;
    for (byte b : message.getBytes()) {
    	result = CRC.update(CRC.CRC16, result, b);
    }
  
    CRC<CRCConfig, CRCComputer> crc = new CRC<>(CRC.CRC16);
    String message = "...";
    Long result = null;
    for (byte b : message.getBytes()) {
    	result = crc.update(result, b);
    }
