Description

The list of methods to do CRC32 Byte Array are organized into topic(s).

Method

longcrcBytes(byte[]... data)
calculates the crc32 of all byte arrays 
CRC32 crc = new CRC32();
for (int i = 0; i < data.length; i++) {
    crc.update(data[i]);
return crc.getValue();
StringcreateRandomCrc32Hex()
create Random Crc Hex 
return createCrc32Hex(createRandomString());
CRC32getCRC()
thread-singleton crc engine 
return crcProvider.get();
longgetCrc32(byte[] buf)
Get the standard CRC32 checksum of a byte array. 
CRC32 crc = new CRC32();
crc.update(buf);
return crc.getValue();
StringgetCRC32(String str)
get CRC 
java.util.zip.CRC32 crc32 = new java.util.zip.CRC32();
crc32.update(str.getBytes());
String retcrc32 = Long.toHexString(crc32.getValue());
return retcrc32;
intgetCrc32asInt(byte[] in)
Use this method to calculate the CRC32 signature of a byte array. 
if (in == null || in.length == 0)
    return -1;
CRC32 crc = new CRC32();
crc.update(in);
return (int) crc.getValue();
longgetCRC32Checksum(byte[] bytes)
Generate CRC32 Checksum For Byte Array. 
Checksum checksum = new CRC32();
checksum.update(bytes, 0, bytes.length);
return checksum.getValue();
StringgetCRC32Checksum(String pString)
get CRC Checksum 
long decimalChecksum = 0;
String hexChecksum = null;
final String ZEROS = "00000000";
final int CRC32_CHECKSUM_LENGTH = 8;
CRC32 checksumEngine = new CRC32();
checksumEngine.update(pString.getBytes());
decimalChecksum = checksumEngine.getValue();
hexChecksum = Long.toHexString(decimalChecksum).toUpperCase();
