My blog post: Porting Niceware to Rust
A Rust port of niceware. Sections of this README have been copied from the original project.
This library generates random-yet-memorable passwords. Each word provides 16 bits of entropy, so a useful password requires at least 3 words.
The transformation from bytes to passphrase is reversible.
Because the wordlist is of exactly size 2^16, niceware is also useful for convert cryptographic keys and other sequences of random bytes into human-readable phrases. With niceware, a 128-bit key is equivalent to an 8-word phrase.
Similar to the source, heed this warning:
WARNING: The wordlist has not been rigorously checked for offensive words. Use at your own risk.
niceware can be used to generate secure, semi-memorable, easy-to-type passphrases. A random 3-5 word phrase in niceware is equivalent to a strong password for authentication to most online services. For instance, +8svofk0Y1o= and bacca cavort west volley are equally strong (64 bits of randomness).
niceware can be used to display cryptographic key material in a way that users can easily backup or copy between devices. For instance, the 128-bit random seed used to generate a 256-bit ECC key (~equivalent to a 3072-bit RSA key) is only 8 niceware words. With this 8-word phrase, you can reconstruct the entire public/private key pair.

Rust port:
@Kixunil made some fantastic changes w/r/t idiomatic and performant Rust in #2.
Code, tests, and docs are either straight-up ported/copied from, or inspired by niceware.
Original:
Niceware was inspired by Diceware. Its wordlist is derived from the SIL English word list. This project is based on [diracdeltas] work on OpenPGP key backup for the Yahoo End-to-End project.
