extends BufferChecksum
Class Inheritance
Imports
java.util.zip.Checksum
Implements CRC32-C as defined in: "Optimization of Cyclic Redundancy-CHeck Codes with 24 and 32 Parity Bits", IEEE Transactions on Communications 41(6): 883-892 (1993). The implementation of this class has been sourced from the Appendix of RFC 3309, but with masking due to Java not being able to support unsigned types.
