In the case of the serial number only single bits can change. My concerns are the collision probabillity of the CRC32 is to high that I don't detect a change in the configuration. After some google searching I found the birthday problem: https://stackoverflow.com/questions/14210298/probability-of-collision-when-using-a-32-bit-hash/14217471#14217471

In absolute terms that’s a tiny difference though. But as you can see the probability of getting a collision hugely depends on the inputs that you feed into the CRC32 function. If … In the case of the serial number only single bits can change. My concerns are the collision probabillity of the CRC32 is to high that I don't detect a change in the configuration.

and execute it; however the website only executes python files with a particular checksum value. The Solve.java will brute force some bytes of the python file until a collision occurs. It depends strongly on your definition of “simple string.” For two fully random inputs of the same length, and noticeably longer than 32 bits, I’d expect a CRC-32 collision approximately one in [math]2^{32}[/math] of the time.

The value CRC32(G(P)) that makes the hash pass is equal to CRC32(G(password)) where password is the original password, because the function F doesn't have any “random” collision (in fact, it has no known collision, although MD5 and SHA-1 individually do, and even for those hashes individually, collisions require crafting the two source values, not just one and then looking for a collision).

Murmur3F outperforms Java's CRC32 by factor 4 and Guava's implementation of the same hash by factor 10. hash functions collisions. Two observations: 1. 22 Jan 2020 zlib.crc32(b"test") 3632233996.

Is there any collision rate measure for popular hashing algorithms (md5, crc32, sha-*)? If that depends only from output size, it's quite trivial to measure, but I suppose that depends also of distribution and algorithm's internals (and it demands some kind of formal proof, i think). The CRC-32 checksum calculates a checksum based on a cyclic redundancy check as described in ISO 3309 [14]. The resulting checksum is four (4) octets in length. The CRC-32 is neither keyed nor collision-proof. The use of this checksum is not recommended.

I could not find CRC32 collisions on game ROMs.

To make my Almost-Narcissist program, I needed to be able to match the CRC32 value of a given file, the source of the Almost-Narcissist itself. I could only find a PHP CRC32-matcher, and it didn't seem to work. So I wrote a CRC32 value matcher.

There is [*] Appears vulnerable to MS10-092 [>] Description: When processing task files, the Windows Task Scheduler only uses a CRC32 checksum to validate that the file has not been tampered with.Also, In a default configuration, normal users can read and write the task files that they have created.By modifying the task file and creating a CRC32 collision, an attacker can execute arbitrary commands You need to choose a checksum and dunno which, well the 2 most popular ones are the CRC and Adler32 checksum.
