About CRC32 hashes

In general a CRC can be n-bits in length, but most commonly a 32-bit CRC is used. An n-bit CRC has the property that any error run of up to n bits is mathematically guaranteed to produce a distinct CRC checksum. This guarantee is possible because CRCs are computed using a special type of polynomial that is able to guarantee this property. As a special case, this typically means that an error of a single bit (or a single byte) will guarantee that the CRC checksum will fail, regardless of any other property of the transmitted data, including its length. This is a powerful property, since it guards against the most common type of transmission errors.
