Ip4v Rainbow Table
I won't post the whole thing, but will say an IPv4 address in dotted decimal notation matches your MD5 hash and the correct match starts with 84.200 (in the format x.x.x.x - no newlines or spaces or anything …

Why are MD5 collisions dangerous?
But the bottom-line is that security-conscious developers need to know to avoid MD5 when collision resistance is necessary. … Or maybe they feel that since MD5 lacks collision resistance, that MD5 is inherently weaker than the others and more likely to be fully broken against preimage attacks before SHA-1/SHA-2 hash functions …

What does it mean by the 'Hash of a malware'?
Assuming you have GNU coreutils or their equivalent with the md5sum file, like:
# md5sum name_of_file
d41d8cd98f00b204e9800998ecf8427e name_of_file
where d41d8cd98f00b204e9800998ecf8427e is the MD5 …

Cryptosytem Question
Really you need to establish trust in transmitting the md5. … (While md5 suffers collision attacks -- its possible to construct two different files (modifying both) such that md5(f1) = md5(f2), no published attack has shown md5 is vulnerable to preimage attacks - …

Is possible to fake md5sum?
MD5 is known to be broken for collision attacks. It is possible to generate a pair of documents m1 and m2, such that MD5(m1) = MD5(m2). … that MD5(m) = h. …

Why does MD5 hash starts from $1$ and SHA-512 from $6$? Isn't it weakness in itself?
Second, you are wrong about those being md5 or sha512 hashes; the values stored in your /etc/shadow are md5crypt or sha512crypt, which involves a strengthening procedure (many rounds of a md5 or sha512 …
