I have an old system that can do PBKDF2 with HMAC using MD5, but not SHA-2. Now I know that MD5 is insecure and shouldn’t be used for new applications, but https://crypto.stackexchange.com/a/9340/7075 seems to indicate that HMAC-MD5 is st… Continue reading Is pbkdf2 with hmac using md5 still secure?
I’m working on a small game website and don’t expect too much traffic.
Would md5(time . rand) suffice to have a "random enough" identifier for a game?
(Or is it easy to get a clash that way?)

I wanted to make a file scanning application which scans for virus. I am using the MD5 method(by seeing a tutorial) but I did not understand what exactly is MD5, for what is it used and is it only for ".txt" files?
I’m doing an educational hash research. I generated MD5 hash using online tools and cracked it within a second using Hashcat and certain wordlist (yes, one second). Then I produced a WPA handshake using this same password that I used for M… Continue reading Significant differences in hash cracking speeds? [duplicate]
I was reading this article about MD5 hash collisions in which it clearly states that these two strings (differences marked with ^):

I was reading this article which talks about a design to shorten URLs, and in the design section, it says that the given URL can be hashed using a hashing algorithm such as MD5, and then be encoded for display purposes using base64 or simi… Continue reading Why would one need to encode an MD5 hash string? Is it unsafe to display unencoded?
If I use MD5 but not for cryptography purposes, and not for any authentication or authorization mechanism, Am I in violation of FedRamp Moderate?

This is not for passwords. I understand that MD5 and SHA-512, etc… are insecure because they can have collisions.
However, is it still possible to have a collision if the string length is less than the hash size (i.e. MD5 is a 32 charact… Continue reading SHA & MD5 Collisions for shorter strings
In the pantheon of computer forensic analysis, practitioners are often faced with many problems that require innovative solutions. Every case or incident presents us with new challenges, new approaches, new work-arounds and new exploits. For many years… Continue reading Virtual Forensic Computing (VFC) From MD5
