CRC Checksum Verification
The libshare library provides a method to generate and print CRC checksums derived from segments of binary information.
The algorithm computes a 64-bit number from the data segment.
The algorythm is a modified form of adler32 suitable for 64bit generation. The checksum is not compatible with standard adler based algorythms.
The checksum is used to generate a libshare "Key" () used through-out the libshare library suite.
