The fixtures of spec 67 for format 3, each with its record, its BODY,
its inspect output and, for time_and_key, its .dkk:
- format3_single, format3_tree (five files in three folders, one over
two STREAM chunks, one without mtime, a comment and a declared
author), format3_comment_only (no files; a TAB in the comment),
format3_bloque256 and format3_time_and_key_portable, written with
EncryptFiles;
- format3_area_1024, format3_security_v2 (verdict X),
format3_signature_unsupported (an author-signature of alg 1 with a
random key of 32 bytes and a random signature of 64: F1) and
format3_seal_unsupported (that and a seal of seal_type 1: F1 and S1),
which only a generator of test vectors writes (62.1 rule 13), built
with testkit.Build.
The record of a format 3 fixture adds the area, SECURITY_CBOR,
HEAD_CBOR, the salt, the comment, the declared author, the head
extensions, the offset of CONTENT in BODY, each file with its layout,
SHA-256 and mtime, and the verdicts with their lines; its plaintext
file is BODY. The generator writes, then recovers every value by
opening layer by layer for the three formats alike, and refreshes the
records of format 3 through a Sink.
Tests: the conformance test checks BODY, the head, security and every
file, and opens through a MemorySink; the .dkk tests take the .dkk of
formats 2 and 3 too (spec 68); the CLI decrypts five of the fixtures
into folders; the control fuzz target decodes with the three schema
versions. The differential corpus gains two bases, format3_single and
format3_time_and_key_portable, one per policy: 5110 cases, the earlier
ones unchanged.
