locator_seal.dart ports the writing side of package locator of
datekeys-go: sealLocator, Seal of Go, marshals the locator, makes the
tlock recipient of the round and encrypts, in that order and with the
texts of Go, and wipes the plaintext; newEnvelope, NewEnvelope of Go,
draws I_SOBRE, encrypts the .dkc for it with ageEncrypt of stage 6a and
splits the file with splitEnvelope of stage 7a.
tool/locator_seal_go_vectors.go writes test/vectors/locator_seal.json:
Seal of locators of one to three blocks for rounds from 1 to the last of
Quicknet, its refusals, NewEnvelope of .dkc of 0 bytes to 1 MiB and a
whole flow, while crypto/rand reads the keystream of SeededRandomSource.
With the same seed, Dart draws the same values and writes the same bytes
in every case, and the sealed locators open with the release of their
round.
In the other direction, tool/seal_interop_dart_samples.dart writes sealed
locators with their envelopes, author key files and signatures from the
recipes of test/seal_interop_support.dart, and
tool/seal_interop_go_verdicts.go opens them with locator.Open,
OpenEnvelope, authorkey.Read and crypto/ed25519: Go reads all fifteen.
test/vectors/seal_interop.json keeps the verdicts and the digest of each
file, which the tests write again.
