Segurança Ferramentas
Hash generators, JWT decoders, password tools, subnet calculators — security utilities.
Overview
Security utilities deserve special care: by definition, you're processing sensitive data (secrets, tokens, hashes, credentials). The tools in this category all run client-side, never log to servers, and use cryptographically-strong primitives from the browser's Web Crypto API. Use them for testing, debugging, and verification — without ever sending the secret elsewhere.
Common Use Cases
- →Generate strong, random passwords with cryptographic randomness.
- →Decode and verify JWTs (with secret or public key).
- →Compute SHA-256 hashes to verify file integrity.
- →Calculate IP subnets, CIDRs, and network ranges.
Frequently Asked Questions
Is it safe to paste my JWT into a web tool?
Only if the tool runs entirely client-side (this one does). To verify, open dev tools' Network panel before pasting — confirm no network requests during processing. Never paste tokens into tools that send them to a server.
Why use SHA-256 over MD5?
MD5 is cryptographically broken (collisions are easy to find). Use it only for non-security tasks like cache keys. SHA-256 remains secure for all current applications including TLS, Bitcoin, and code signing.
What's a good password length?
16 characters for high-value accounts (email, banking), 12+ for general use. Length beats complexity — a 20-character all-lowercase password is stronger than a 10-character mixed-case-and-symbol password.
