I know that when setting up VTP across switches in a network you should set a secret/password to prevent unauthorized requests. My question is I know that this uses an MD5 hash to ensure that attackers don’t falsify any reque… Continue reading How does VTP authentication prevent unauthorized access (Can the password be cracked given captured packets)
Nowadays no one dares to defend md5 for any use, and of course they should not!
However, much popular software still uses md5 in applications such as password hashing (although it’s not simple/plain md5 and probably uses adv… Continue reading Why does some popular software still use md5?
There are a lot of research papers available online that discuss vulnerabilities of MD4 algorithm, but I couldn’t find any implementation of these.
Uptill now I have used tools like John the Ripper or MDCrack and tried to bruteforce the h… Continue reading Tool for generating MD4 collisions
This is something I never understood about hashing functions. I know that algorithms like whirlpool and blowfish both produce outputs that don’t follow this pattern, but why is it that most do? Is it some kind of hardware/s… Continue reading Why do most hashing functions produce hashes that have characters a-f 0-9?
After all these articles circulating online about md5 exploits, I am considering switching to another hash algorithm. As far as I know it’s always been the algorithm of choice among numerous DBAs. Is it that much of a benefit to use MD5 in… Continue reading Is MD5 considered insecure?
It is well known that SHA1 is recommended more than MD5 for hashing since MD5 is practically broken as lot of collisions have been found.
With the birthday attack, it is possible to get a collision in MD5 with 264 complexity… Continue reading Is SHA1 better than MD5 only because it generates a hash of 160 bits?

It’s still commonly recommended way of hashing passwords, even if its insecurity had been proven in 1996:
Therefore we suggest that in the future MD5 should no longer be implemented in applications like signa- ture scheme… Continue reading Why do people still use/recommend MD5 if it has been cracked since 1996?
It’s still a commonly recommended way of hashing passwords, even if its insecurity had been proven in 1996:
Therefore we suggest that in the future MD5 should no longer be implemented in applications like signature schemes, where a collis… Continue reading Why do people still use/recommend MD5 if it has been proven weak since 1996?
