How to Create a SHA-512 Hash of a Password.md

Introduction:

• This Page shows how to make a SHA-512 hash. This is needed for creating a hash of a SysAdmin user account password as it allows other SysAdmins to set each other's passwords without knowing what the password is.

Workflow Prerequisites

• A Linux or Mac computer.
  • Linux: The mkpasswod binary (found in the whois package).
  • Mac: Python3 and passlib

Create the Password Hash

Ubuntu

1. Open Terminal.
2. Make sure mkpasswd is installed: sudo apt install -y whois
3. Run mkpasswd -m sha-512.
4. Type in whatever it is you want to hash and press return or Enter.
5. Terminal will print out the SHA-512 hash.

Mac

1. Open Terminal.
2. Make sure passlib is installed: pip3 install passlib
3. Generage the password hash: python3 -c "from passlib.hash import sha512_crypt; import getpass; print(sha512_crypt.using(rounds=5000).hash(getpass.getpass()))"
4. Type in whatever it is you want to hash and press return or Enter.
5. Terminal will print out the SHA-512 hash.
