MD5 is broken so badly that this hash starts and ends with 1337.
Next step is to generate that type of quine when image has two pieces of string data: one is hash of image with no quine and another is exactly same image with two hashes.
- londons_explore 4y agoWhat are you talking about?? The hash does not start 1337... The hash of the example files is f54e7363d9c72ebf81605e2b38fa2be5. The crc32 is deadbeef.
- Retr0id 4y agoThey're describing the PNG hashquine, which is referenced near the start of the article.
- pxx 4y ago0x1337 is only two bytes. 2^32, for four bytes, is not a particularly large number.
- dmitrygr 4y ago1 out of every 4 billion random files will have an md5 that matches your description. Same for sha1, sha256, sha512, and any other proper hash function... Any proper hash function guarantees that any given bit of the output has an equal chance of being a 1 or a 0 for a random input. So for a specific pattern in 32 specific bits, there is a 1/2^32 chance in any hash func
