❓ Security Tools FAQ
What types of security calculations can I perform?
You can encrypt and decrypt data using AES, RSA, Blowfish, and Triple DES; generate hashes (MD5, SHA-1, SHA-256, SHA-512, SHA-3, BLAKE2); check password strength and entropy; calculate subnet masks and IP ranges; assess CVSS scores; generate cryptographic keys; validate JWT tokens; and analyze security logs and compliance.
How do I generate a strong password?
Use our Password Generator. You can specify length, include/exclude character types, and generate cryptographically secure passwords.
How do I calculate password entropy?
Use our Password Entropy Calculator. Enter your password, and it will compute bits of entropy based on character set size and length.
What is the CVSS score and how is it calculated?
CVSS (Common Vulnerability Scoring System) measures the severity of vulnerabilities. Use our CVSS Calculator to compute the base score, temporal, and environmental scores based on metrics.
How do I check if a file has been tampered with?
Use our File Integrity Checker. Compute a hash (MD5, SHA-1, SHA-256) of the file and compare it with a known hash to verify integrity.
How do I generate an RSA key pair?
Use our RSA Key Generator. Specify the key length (e.g., 2048 bits) and it will generate a public/private key pair with optional encryption.
How do I decode a JWT token?
Use our JWT Token Decoder & Verifier. Paste your JWT, and it will decode the header, payload, and verify the signature.
Are these tools suitable for professional security assessments?
Yes, many tools follow industry standards (NIST, OWASP) and are useful for penetration testing, vulnerability management, and security audits.
How often are new security tools added?
We regularly add new tools based on user requests and emerging security needs. If you have a suggestion, please contact us.
Can I use these tools for educational purposes?
