🎁 Typing Animation β€” Special Christmas Gift:

Experience my Typing Animation - a high-performance security awareness module in HTML/CSS/JavaScript. Featuring 204 carefully selected phrases that challenge assumptions about password hygiene and 2FA, this tool transforms security education into an engaging visual experience.

Combining visual impact with behavioral friction, it encourages users to rethink password practices before typing predictable patterns like "123456" again. This is not just aesthetics - it's smart security user experience that makes your digital environment more resilient.

Features visual impact combined with behavioral friction, transforming security education into an engaging experience that encourages users to rethink their password practices.

Enhance your knowledge with 204 animated phrases, protect your accounts with strong passwords, biometrics and 2FA, and review your security practices.

πŸŽ… Welcome to My Digital Christmas Universe

"If your security depends only on fingerprints and SMS codes, congratulations β€” you've already lost to the hacker and the curious aunt who saw you unlock your phone."

I'm Gerivan Costa β€” a developer passionate about security, science, and creativity. Here you'll find projects that combine innovation with purpose, always focused on continuous learning and meaningful contributions to the open source community.

My portfolio features cutting-edge tools like the Transformers Interactive Neural Network Visualizer, which demonstrates the future of information visualization through interconnected neural networks. This represents the next frontier in understanding complex data flows through artificial intelligence systems.

The Cyber Neural Network visualizer demonstrates the future of information visualization through interconnected neural networks. It's based on a Multi-Layer Perceptron (MLP) architecture, (introduced in the paper "AIive: Interactive Visualization and Sonification of Neural Networks in Virtual Reality" – Lyu; Li; Wang, 2021), featuring real-time forward propagation visualization. This represents the next frontier in understanding complex data flows within artificial intelligence systems.

The Transformer Neural Network visualizer refers, in the context of modern AI, specifically to the "Transformer" architecture (introduced in the paper "Attention is All You Need" – Vaswani et al., 2017), used in models like BERT, GPT and Grok. This architecture is revolutionary for replacing recurrent networks (RNN/LSTM) with self-attention mechanisms, enabling efficient parallel processing of entire sequences without strict temporal dependencies. It "transforms" data representations through encoder/decoder blocks with multi-head attention.

Explore innovative security solutions like the DNAPass Password Generator, which unites biotechnology and digital security by transforming DNA sequences into cryptographically secure passwords. This innovative approach introduces biological encoding into password generation, creating truly unique and complex authentication systems.

Discover the EntroPy Password Generator ecosystem, featuring Python CLI versions for Windows/Linux and responsive web implementations. The entropy-driven security model ensures maximum randomness and resistance to brute force attacks, leveraging real entropy sources instead of predictable pseudo-random algorithms.

XPhrase Generation is an expressive phrase generator that uses 4,000 specific words selected from three languages β€” English, Portuguese and German β€” to create sentences. The project allows generating a single phrase or multiple phrases, always with a length between 3 and 21 words. In single phrase mode, the system asks for the desired number of words and produces a sentence accordingly. In multiple phrase mode, it first defines the number of words per phrase and then the number of phrases, between 5 and 10, ensuring consistency in length. Each word must contain at least one special character and one digit, and the final word must end with an uppercase letter. The language order is randomized, making the output varied and dynamic.

πŸš€ XPHRASE GENERATION β€” Expressive phrase generator β€” strong, modern, and minimalist

XPhrase Generation is a multilingual phrase generator designed for use in command-line interfaces (CLI) and in a web browser version. It creates expressive, randomized phrases using words from Portuguese, English, and German, interlinked with special characters and digits.

The principle of randomness enables the generation of over 12.6 trillion unique combinations by interconnecting words from three languages, along with the inclusion of special characters and numerical digits.

Key Features:

"Unleash your creativity β€” Create unique phrases with XPhrase!."
