Efficiently generate cryptographically strong random strings of specified entropy from various character sets.
TypeScript definitions for entropy-string
Calculate the entropy of a password string, but fast!
Cryptographic key pairs for the XRP Ledger
Generate more entropy to combine with Node's crypto.rng or window.crypto
Exodus BIP39 module
Meteor's Random Package for Straight Node
A small implementation of `crypto.getRandomValues` for React Native. This is useful to polyfill for libraries like [uuid](https://www.npmjs.com/package/uuid) that depend on it.
TypeScript definitions for fast-password-entropy
Generate XRPL Accounts with a number-based secret: 8 chunks of 6 digits
Chi-squared distribution entropy.
Deterministic random bit generator (hmac)
Generate XRPL Accounts with a number-based secret: 8 chunks of 6 digits

BIP39 mnemonic for key derivation schemes
Meteor's Random Package for Straight Node – with built in crypto module
Cryptographic key pairs for the XRP Ledger
Calculate the shannon entropy of a buffer
Shannon entropy estimator with dictionary, l33t, and pattern detection for sentinel-password. Zero runtime dependencies; ≤ 30 KB gzipped (CI enforced).
Meteor's Random Package for Straight Node
MetaMask fork of @scure/bip39: a secure, audited & minimal implementation of BIP39 mnemonic phrases
Beta distribution differential entropy.
Gamma distribution differential entropy.
A fast implementation of a fisher-yates shuffle that does not mutate the source array.
Outputs a variety of information on the entropy of a given string
Generate a string with a target entropy
Train and predict string entropy based on character n-grams.
A wrapper for the National Institute of Standards and Technology (NIST) Randomness Beacon 'cause sometimes you need to get a 512-bit full-entropy bit-string programmatically. You never know.
A Ruby library for encrypting and decrypting strings in the 3ncr.org/1#... envelope format (AES-256-GCM with a 12-byte random IV). Supports raw 32-byte AES keys, SHA3-256 derivation for high-entropy secrets, and Argon2id derivation for low-entropy secrets such as passwords.
