- ibe.ts gains encryptOnG2RFC9380, EncryptCCAonG2 of kyber with the
suite of tlock for Quicknet. Qid is H(id) on G1 with the RFC 9380 DST,
sigma comes from crypto.getRandomValues, U = r·G2, V = sigma XOR
H2(e(Qid, key)^r) and W = msg XOR H4(sigma). The key passes the
canonical gate, and sigma and the masks are wiped. encryptOnG2WithSigma
takes a given sigma, for the vectors only; index.ts exports neither.
- tlock.ts adds timeRecipient, the age-encryption Recipient of
OUTER_TIME_AGE, as Go's agewrap.TimeRecipient. It writes the stanza
"tlock <round> <chain hash>" with the checks and texts of
NewTimeRecipient: the scheme and the pinned key, then the round range.
age-encryption has no labels, so the writer of phase 3 adds it alone.
Vectors, in src/lib/dkc/testing/tlock-vectors.json from
scripts/tlock-go-vectors.go:
- Fixed-sigma encryptions of 1, 16 and 32 bytes for rounds 1000 and
1001. Go restates EncryptCCAonG2, since kyber draws sigma itself, and
checks the restatement with ibe.DecryptCCAonG2 and tlock.TimeUnlock.
encryptOnG2WithSigma reproduces them byte for byte.
- The samples of scripts/tlock-ts-samples.mjs, which Node runs on the
TypeScript sources: IBE bodies and age files that this library made
for rounds 1000 and 1001. Go opened every one: the bodies with
tlock.TimeUnlock and the age files with age.Decrypt and
agewrap.NewTimeIdentity, the identity of step 11. It got the same
file keys and plaintexts, and the samples are frozen with those
verdicts.
tlock.test.ts replays both blocks, the random round trip, the
rejections with their texts, and an age file sealed with timeRecipient
and opened with the step-11 identity of open.ts. Coverage of ibe.ts and
tlock.ts is 100 %, now a threshold for tlock.ts too. Step 6 of the plan
is recorded as done: the canonicality amendment is in spec-v0.8.2.
npm run verify is green: 2,567 tests. The site does not change.
