CRYPTOGRAPHY-SECURITY Utilities
Choose a specialized option to begin instant real-time conversion.
Key length ↔ security bits — RSA vs AES equivalence
Compare security levels (bits of security) across symmetric keys, RSA, and Elliptic Curve Cryptography (ECC) based on NIST standards.
Hash output size — MD5 ↔ SHA1 ↔ SHA256 ↔ SHA512 bits
Analyze hash function characteristics (MD5, SHA-1, SHA-2, SHA-3), including bit size, hex length, collision vulnerability, and use cases.
Entropy bits ↔ password strength — character set + length
Calculate Shannon entropy bits based on character pool variety and length. Estimate brute-force resistance across various threat models.
Certificate validity — days ↔ expiry date calculation
Convert between certificate lifetime in days, months, or years, and calculate exact UTC expiration times with leap year support.
Base64 ↔ hex ↔ binary — encoding format converter
Convert raw text strings or bytes bidirectionally between Base64, Hexadecimal, Binary, and standard ASCII formats.
