Notes related to using public/private keys to encrypt data.
This section generates a new private key and extracts the public key.
openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:4096
openssl rsa -pubout -in private_key.pem -out public_key.pem
I hereby claim:
To claim this, I am signing this object:
| #!/usr/bin/env python | |
| import binascii | |
| def getHex(string): | |
| x = binascii.hexlify(string.encode()) | |
| y = str(x,'ascii') | |
| print("hex ", y) |
Sometimes /dev/urandom sounds nice.
$ cat /dev/urandom | padsp tee /dev/audio > /dev/null
What about /boot?
$ sudo cat /dev/nvme0n1p2 | padsp tee /dev/audio > /dev/null
This brief guide will enable fix-on-save in VScode for js and vue files.
ESLint needs to be installed twice: once inside your project and once globally.
# Install globally
$ npm install -g eslint
# Install in project
| #!/usr/bin/env python3 | |

| # This script walks block storage devices and locates | |

| # finally formats the new LV as XFS. | |

This gist will explore how to leverage a "dotenv" ecosystem to mange application credentials.
The gist follows code in the repo https://github.com/rmrfslashbin/python-dotenv-poc.
The Twelve-Factor App concept provides numerous best-practice guidelines for applications and scipts. This gist will provide a python-based foundation, using the dotenv concept, to manage application credentials as described here: https://12factor.net/config
