Q1: What is the difference between CRC32 and MD5 functions? The CRC32 function returns a 32-bit integer Cyclic Redundancy Check (CRC32) value. The MD5 function calculates the checksum of the input value using a cryptographic Message-Digest algorithm 5 and returns a 32 character string of hexadecimal digits (0 - F). Q2: Where should I use CRC32 and MD5 functions? Use CRC32 to find data transmission errors. CRC32 is, evidently, 32 bits, sha1 () returns a 128 bit value, and md5 () returns a 160 bit value. It is important when avoiding collisions.

One big difference between CRC32 and MD5 is that it is usually easy to pick a CRC32 checksum and then come up with a message that hashes to that checksum, even if there are constraints imposed on the message, whereas MD5 is specifically designed to make this sort of thing difficult (although it is showing its age - this is now possible in some situations). The CRC32 function returns a 32-bit integer Cyclic Redundancy Check (CRC32) value.

I read that CRC32C (alias Castagnoli) is better than CRC32 (sometimes referred as CRC32B) in detecting errors but what that exactly means and how to check it didn't mention. I know they use different polynomial but that alone doesn't explain that.

md5 gives 160-bit value that mean it is very complex and there may be consumed years to get the original value for hackers. sha1 is 128 bit while crc32 generates 32 bit hash value. We use md5 not so frequently in our websites because it cause speed breakdown of website. Re: MD5 versus CRC32 We are considering adding MD5 support in a future version, but it's a low priority, and I don't think it will be as useful as you're hoping. If you're checking a just-burned CD or file copy you should just use the binary comparison. It does a byte-by-byte check on the two files, so it doesn't even have the miniscule chance of collision that MD5 has.
