web3.gas-seed-entropy Calculator
Calculates wallet seed phrase entropy bits and the brute-force resistance of a BIP-39 mnemonic for gas fee estimation for blockchain transactions wallet security. A 12-word BIP-39 mnemonic has 128 bits of entropy (from a 2048-word list) — 24 words provides 256 bits, equivalent to AES-256 key strength.
Inputs
Word Count
Reference formula or conversion factor shown for context.
Passphrase Chars
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Bits Per Word
Measure of disorder in the system (J/mol·K). Spontaneous processes tend to increase entropy (Second Law of Thermodynamics).
Results
seed entropy
Sample size or count used in the calculation.
total entropy
The combined total across all inputs and components.
years to crack
Reference formula or conversion factor shown for context.
