Simple Ruby wrapper for encryption/decryption using OpenSSL
class Crypto
# encrypts data with the given key. returns a binary data with the
# unhashed random iv in the first 16 bytes
def self.encrypt(data, key)
cipher = OpenSSL::Cipher::Cipher.new("aes-256-cbc")
cipher.encrypt
cipher.key = key = Digest::SHA256.digest(key)
random_iv = cipher.random_iv
cipher.iv = Digest::SHA256.digest(random_iv + key)[0..15]
encrypted = cipher.update(data)

MySQL to Sqlite converter
#!/bin/sh
# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.
# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.
# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite

Microservice Proxy/Gateway Solutions

MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.
