How many md5 hashes per second

In specific case this research was made for hashed string will be passed as API request. So if API Key is something like chars, Secret Key is chars and time is 10 chars, total length of string to hash is chars. Since it is being passed as request param it is better to be as short as possible. Based on all data so far SHA is selected. It is from secure SHA-2 family. It is much faster than SHA with shorter stings and it produces 64 chars hash. Important is that comparison is very dependant on specific implementation Apache Commons Codec , the specific purpose of use generate a secure token to be sent with API call.

If their speed for given context is several times faster than secure SHA-2 ones and security is not that much important they can be chosen though. When choosing cryptographic hash function everything is up to a context of usage and benchmark tests for this context is needed. Automation Rhapsody Automate with enthusiasm. A gtx can guess at a rate of 25 billion passwords per second for plain md5. In that case you could write a bash or a python script to iterate over the 1,, possibilities.

Johnride, don't benchmark from a file. Run it from data in memory or even simpler just rehash the same value.

Robino that's what openssl speed does, which is the first and most meaningful benchmark. No it does not depend. There is discrete number of operations both functions need to perform, fluctuations are result of CPUs or implementations heuristics — JJ Roman.

At a first look it's not clear if SSE2 is used to speed up one MD5 thread or to pair a few parallel MD5 threads; the latter is of course easy for most algorithms, but that doesn't count as benefiting from SSE2 as usually what's needed is a single stream of data.

Related In addition to using those two already mentioned world lists, I've tried cracking passwords using the following techniques:. All these attacks can be customized and extended using rules.

I've cracked k passwords, cca. In 12 hours, I've cracked almost all of them, I was left with passwords not cracked only because I wanted to go to sleep. I'm pretty confident that I'd get all of them if I'd keep the cracking running for a few more hours. There's no single password-manager-generated password on the list of not cracked passwords, and all of them are similar to what has been cracked. So I think that the rest could be cracked too relatively quickly.

I think the passwords in the leak could have been hashed somehow. Cracking cryptographically salted SHA-1 a hash Mall. I build web applications and I'm into web application security.

I like to speak about secure development. My mission is to teach web developers how to build secure and fast web applications and why. PHP application security December 13—16,
