Then adding polynomials - is just exclusive-or, and multiplying a polynomial by x is a right shift by - one. If we call the above polynomial p, and represent a byte as the - polynomial q, also with the lowest power in the most significant bit (so the - byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p, - where a mod b means the remainder after dividing a by b. - - This calculation is done using the shift-register method of multiplying and - taking the remainder. The register is initialized to zero, and for each - incoming bit, x^32 is added mod p to the register if the bit is a one (where - x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by - x (which is shifting right by one and adding x^32 mod p if the bit shifted - out is a one). We start with the highest power (least significant bit) of - q and repeat for all eight bits of q. - - The table is simply the CRC of all possible eight bit values.

It consists - of the entry's header, as well as the entry's File. Entries - can be instantiated in one of three ways, depending on how - they are to be used. -

- TarEntries that are created from the header bytes read from - an archive are instantiated with the TarEntry( byte[] ) - constructor. These entries will be used when extracting from - or listing the contents of an archive. These entries have their - header filled in using the header bytes. They also set the File - to null, since they reference an archive entry not a file.

-

- TarEntries that are created from files that are to be written - into an archive are instantiated with the CreateEntryFromFile(string) - pseudo constructor. These entries have their header filled in using - the File's information. They also keep a reference to the File - for convenience when writing entries.

-

- Finally, TarEntries can be constructed from nothing but a name. - This allows the programmer to construct the entry by hand, for - instance when only an InputStream is available for writing to - the archive, and the header information is constructed from - other information. In this case the header fields are set to - defaults and the File is set to null.
