What "info at b1g dot de" wrote about MD5 is not completely correct. He wrote:
"MD5 (32Byte) is more precise then CRC32 (4Byte)"
It is correct that MD5 is "more precise" than CRC32, but it does not contain 32 bytes, but
16 bytes. (SHA-1: 20 bytes)
Apart from that one cannot compare MD5 to CRC32 just by comparing its number of bits. The underlying
algorithm is more important.
