Is there a tool to convert each password in a text file into sha256 hash without writing any program? I want to convert each password in "rockyou" password file into their SHA256 form line by line. Do you know any tool for it?
… Continue reading How to hash each password into their SHA256 hashes using a simple tool [migrated]
I am aware of at least one solution for this, but times change and standards change, and I’m not an expert in this field.
So for the average person looking to create secure hashes for passwords and other uses, what is a good tool for that?… Continue reading What’s a good password hashing tool for the general public? [closed]
I know the string "03a34b99f22c790c4e36b2b3c2c35a36db06226e41c692fc82b8b56ac1c540c5bd" generates the SHA-256 hash 4c0b2d2f119a09b607cb273a745b2b0430d5192e0c4e536f932be5d1a6be5883 using https://privatekeys.pw/calc

Usually when we think of Bitcoin miners, we imagine huge facilities of server racks doing nothing but essentially wasting energy, all for the chance that one of those computers amongst …read more Continue reading Tiny Bitcoin Miner Plays The Lottery
Is it possible to generate a file with a given sha256sum checksum?
That is, reverse the process of a sha256sum checksum. That is, if we have a checksum, can we generate txt file data (need not be original) whose its checksum is equal to th… Continue reading Is it possible to generate a file with a given sha256sum checksum?
I was burning an iso file into the sd card with pi imager and I doubled checked the hash before the burning and after and I got different results

I have just begun my bachelor’s in IT security and we have been presented with a list of exercises. I have completed all, but one of them. (Note: this is to be done in Python).
In this exercise we are given a SHA256 hash, which is a user’s… Continue reading Need help cracking a SHA256 hash, based on a list of hint strings [closed]

This Website can reverse sha256.
So how is it that it is supposedly a "irreversible one-way function"?
Is there anything wrong with hashing(with SHA256) the shared secret generated by ECDH that is 384 bits long and using that as the AES key? Is there a difference between that and, say, truncating the 384 bits down to 256.
Edit:
And would th… Continue reading Generating AES 256 key from ECDH P-384
