I generate a random string of 32 characters and then compute the SHA-512 hash then I encrypt the unhashed string. I then save the encrypted text and hash to the database. Is it okay to store the hash of the original text? Will it make the … Continue reading Storing the hash of the plaintext and the encrypted plaintext next to each other [closed]

I want to test how secure our internal application is and I was wondering if it is possible to figure out the salt or something if I know the following info about a few accounts (basically the hash and the actual password for multiple user… Continue reading Figure out the Salt? [duplicate]

I just saw this article and many like them before where they use a video of some random movement and a hashing function to make a cryptographic random number generator
but I’m always curious why this is as "unpredictable" as they… Continue reading Random based on video input, why isn’t there some predictability [migrated]
Context:
When the Twitch whole code repository was leaked, it created multiple discussions on social medias.
And one day I was on Reddit and said that the leak of the hashing algorithm and the salt would possibly put ALL of the website acc… Continue reading How bad would a Hash algorithm leak would be?
I have a file zip locked and I used zip2john.exe "file" > hash.txt since it contains videos and pictures it is big and hash is so long that I don’t know how to make it readable by hashcat. I know that these forum is not for ha… Continue reading zip2john hash to hash readable by hashcat
I have video files stacked in zip and I forgot the password.
I want to use hashcat, because john will take much longer, but the hash from hash zip2john isn’t compatible and I don’t know how to convert it
Hash from zip2john:
$zip2$*0*3*0*… Continue reading Converting zip2john output to hashcat
I have a microservice which sole purpose is to serve as a cache for other microservices. The point of the cache is to speed up processing, but the strong password hash algo counter that purpose. (Company policy require all service to be se… Continue reading Weak password hash + strong rate limiter = secure?
So if I got this right from my intense research, the following procedure would be preferrable:
Use the PBKDF2 key derivation function to derive a secret key from the users password on the client side.
Use the derived key, which was generat… Continue reading Algorithms when using client side hashing plus server side hashing
