Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

gx-twofish64

v1.0.2

Published

A library for encrypting and decrypting data using the Twofish algorithm and Base64 encoding. Based on the Genexus implementation (Encrypt64 and Decrypt64).

Readme

gx-twofish64

Encriptación y desencriptación compatible con GeneXus usando el algoritmo Twofish y codificación Base64.

Este paquete reproduce la lógica de Encrypt64 y Decrypt64 usada en GeneXus, permitiendo interoperabilidad con sistemas desarrollados en esa plataforma.

Instalación

npm install gx-twofish64

Uso

import { encrypt64, decrypt64 } from 'gx-twofish64'

const text = 'Hola mundo'
const hexKey = '21972247ba570855360dbf70c8fa2e0e' // Clave hexadecimal válida (32 chars para 128 bits)

const encrypted = encrypt64(text, hexKey)
console.log('Encriptado:', encrypted)

const decrypted = decrypt64(encrypted, hexKey)
console.log('Desencriptado:', decrypted)

API

encrypt64(text: string, hexKey: string): string

  • text: Texto plano a encriptar.
  • hexKey: Clave en formato hexadecimal. Debe tener 16 bytes (32 caracteres hex).
  • Devuelve: Texto encriptado como Base64.

decrypt64(base64Text: string, hexKey: string): string

  • base64Text: Texto encriptado en Base64.
  • hexKey: Clave en formato hexadecimal (misma que la usada para encriptar).
  • Devuelve: Texto desencriptado.

Detalles técnicos

  • Algoritmo: Twofish en modo ECB.
  • Tamaño de bloque: 16 bytes.
  • Padding: Se utiliza padding con espacio (0x20) como hace GeneXus.
  • Codificación: Base64.

Compatibilidad

✔ Compatible con valores generados por Encrypt64() y Decrypt64() de GeneXus.
