authorkey.ts ports the package authorkey of datekeys-go at spec-v0.12:
generate with an injectable random source, fromSeed, publicKey, sign,
clear, secret, a toString that hides the secret, publicString, parsePublic
(canonical, on the curve, not of small order), parseSecret, marshal, and
the key file encrypted with age and scrypt of work factor 16, read with a
maximum of 16, 64 KiB and the lines of bufio.Scanner, with the error texts
of Go and of Go's age byte for byte. Key strings are read as Go strings,
with the case and space tables of Go's package unicode (gounicode.ts,
generated by scripts/go-unicode-tables.go).
ed25519sign.ts is crypto_sign of TweetNaCl, as the Dart port, with the
SHA-512 of @noble/hashes: exact arithmetic in Float64Array, secrets never
in BigInt. No new package or module: age-encryption writes the scrypt
stanza, and the STREAM of a key file uses the ChaCha20-Poly1305 and HKDF
already imported.
scripts/authorkey-go-vectors.go, the generator of the Dart port with this
library's output, writes testing/authorkey-vectors.json in an export of
datekeys-go at spec-v0.12: 234 signatures, scalars, keys, Generate and
Encrypt with Go's draws (reproduced byte for byte), 1288 key strings,
3240 runes at the edges of the tables and 130 key files.
