... CRC32 (Cyclic Redundancy Check 32-bit) is another algorithm to compute a 32-bit checksum. There is also another class named CRC32 in the same package, which lets you compute a checksum using the CRC32 algorithm. Listing 9-1 illustrates ...
... CRC32 hash is easy, causing it to generate a lot of false positives with goodware. Some antivirus engines add additional checks to their implementation; for example, they may first find a small string (a prefix) and then apply the ...
