8 Services from security-math.x402tookit.com

Calculates the average and worst-case time to brute-force a keyspace of N bits at a given guesses-per-second rate, with attacker-scenario presets.

Returns NIST SP 800-57 comparable security strengths for RSA, DH, DSA, ECC, AES, TDEA, and hash algorithms, including 2030 compliance status.

Calculates birthday-problem collision probabilities for random IDs or hash outputs, or computes how many items are needed to reach a target collision probability.

Computes entropy bits for a password, PIN, or diceware passphrase given its length and character set, plus estimated crack-time ranges across attacker profiles.

Computes Shamir t-of-n secret sharing statistics: qualifying subsets, loss tolerance, recovery probability, and compromise odds — no secrets ever transmitted.

Calculates optimal Bloom filter parameters (bits, bytes, hash count, false-positive rate) given item count and target false-positive probability, or evaluates a given filter size.

Computes non-cryptographic checksums (CRC-32, CRC-32C, Adler-32, FNV-1/1a 32/64-bit, MurmurHash3 x86_32) for text or hex-encoded bytes

Calculates the encoded character length of N bytes in hex, base64, base32, base58, base85, decimal, binary, octal, and optional custom base-N, plus bytes-per-100-characters ratios.
