Who built Secreta?
Alfredo Costa
Founder & Developer · Costa Software
Alfredo Costa is a software engineer with over 20 years of experience designing and building secure systems. After two decades of working across enterprise security, web application architecture, and cryptographic implementations, he founded Costa Software to focus on what matters most: giving people real control over their digital security.
Secreta was born from a simple frustration — most password managers ask users to trust a company's promise instead of trusting verifiable architecture. Alfredo built Secreta to prove that zero-knowledge security and exceptional user experience are not mutually exclusive. Every encryption decision, every architectural choice, and every line of code reflects a security-first engineering philosophy refined over 20 years of practice.
What drives our security philosophy?
Every feature we build must strengthen at least one of four foundational pillars. If a feature does not help users protect, understand, or control their data, it does not belong in Secreta. These are not marketing slogans — they are engineering constraints enforced in every pull request.
Security
Zero-knowledge architecture where the server cannot decrypt your data, even if compelled. Client-side AES-256-GCM encryption, per-vault isolation keys, and PBKDF2 with 100,000 iterations ensure that a server breach reveals nothing.
Clarity
Security that users do not understand is security they cannot trust. We communicate in human language — 'Only you can decrypt this' — not jargon. Every encryption action is visible and verifiable in the interface.
Trust
Trust is earned through architecture, not marketing. We cannot access your data by design — no backdoors, no master keys, no key escrow. Audit logs prove what the server accesses: nothing.
Sovereignty
Your data belongs to you. You hold all cryptographic keys. Export your data without permission, delete your account completely, and face zero vendor lock-in. If Secreta disappeared tomorrow, your data would still be yours.
These pillars are documented in our public operating philosophy. They guide every product, design, and engineering decision we make — and they always will.
Why is transparency non-negotiable?
Security products that hide their source code are asking you to trust a promise. We believe trust should be verifiable. Secreta's architecture is designed to be inspectable — because the strongest security claim is one that anyone can audit.
Open source is not a marketing strategy for us. It is an accountability mechanism. When our encryption implementation is visible, independent security researchers can verify that our zero-knowledge claims are real — not aspirational. We welcome scrutiny because our architecture was built to withstand it.
We are committed to maintaining transparent development practices, publishing security documentation, and responding to responsible vulnerability disclosures. If you find a flaw, we want to know — and we want the fix to be public.
