DevSecDeck provides developer and security utilities for educational and productivity purposes. Please read the following carefully.
The tools on this site are provided for informational and educational purposes only. They are not a substitute for professional security audits, cryptographic review, or expert advice. Do not rely solely on these tools for production security decisions.
// No guarantee of accuracy
While we strive to ensure correctness, we make no guarantees about the accuracy, completeness, or reliability of any tool output. Encoding, hashing, encryption, and other transformations should be independently verified before use in any security-sensitive context.
// Cryptographic tools
The cryptographic tools (AES-256 encryption, hash generation, HMAC generation, password generation) use the browser's Web Crypto API and are intended for learning, testing, and development use. They should not be treated as production-grade cryptographic implementations without independent security review.
// JWT decoder
The JWT decoder parses and displays token contents but does not validate signatures. A decoded JWT should not be considered verified or trusted. Avoid pasting production tokens containing real secrets — while processing is entirely client-side, treat sensitive credentials with caution.
// SSL certificate inspector
The SSL Certificate Inspector's URL lookup mode sends the URL you provide to a server-side API route. The URL is not logged or stored, and the connection is used solely to retrieve certificate information. Results reflect the state of the certificate at the time of the request and may not represent current conditions.
// Not professional advice
Nothing on this site constitutes professional security, legal, or technical advice. If you require assurance about the security of your systems, consult a qualified professional.
// Limitation of liability
To the fullest extent permitted by law, DevSecDeck and its maintainers shall not be held liable for any damages, losses, or security incidents arising from the use or misuse of any tool on this site.
