Offensive Security Tool: Hashcat
Hashcat
Hashcat is the world’s fastest and most advanced password recovery utility, supporting five unique modes of attack for over 300 highly-optimized hashing algorithms. Hashcat currently supports CPUs, GPUs, and other hardware accelerators on Linux, Windows, and macOS, and has facilities to help enable distributed password cracking.
Brute-forcing has evolved into not just cracking passwords from websites, but also specifically from databases, archived folders/files, backups, hashes and more. This tool is different because of the way it can utilize all your machine’s resources especially if you have a GPU. Depending on the machine used, it will give you an ETA of how fast you can crack, with speeds of testing more than 1000 combinations per second.
It can be used as part of your pentesting, bug bounty especially when you come across a lot of secrets keys that can be analyzed of which encryption is used and crack them accordingly to reveal the hidden content of the encryption. Since it supports almost all known algorithms you can check it out by testing it in a training environment to uncover its true power and speed.
