This room in the teaches about the basics of hashes. It's a walkthrough, so most of the process is included in the room. But I would like to share my findings and additional stuff related to this room.
The purpose of encoding is to transform data so that it can be properly (and safely) consumed by a different type of system. The purpose of encryption is to transform data in order to keep it secret from others.
Output size of MD5 hash is 128 bit. 128 bit = 16 bytes. Because 1 byte = 8 bit.
Due to the pigeonhole effect, collisions are not avoidable
There are 2^8 possibles hashes. 2^8 = 256
2. hashcat is kali tool to crack hash. 'bcrypt' hash code is 3200. Command: hashcat --help
3. Command to run hashcat:
Do not use --force as it will generate false positive and false negative.
4. Crackstation.net can also crack some 'non-salted' hash. Try it too.
I hope this will help you. Thank you.
This blog post is about the Rainbow Table Attack:
Online tools to crack hash. This will also tell you the hash type:
Password should be hashed. Encryption is not the correct term for that:
SHA-rounds means the iteration of SHA function:
Recommended website is enough to find the hash: . Check the image below to understand.
Hash analyser is an online tool: . The image below is the result of the first hash.
This link will show you the list of SHA1 sum:
Check 'Hash cat wiki', provided at task 4:
