Initial implementation of the DateKeys Protocol v0.8.1
Reference implementation in Go, built from the implementation plan
(milestones M0 to M5): datekey, profile, provider, codec, agewrap,
extension, capsule, accesskey, the datekeys CLI, official vectors and
fixtures, the mutation corpus, fuzz targets, interop and live tests,
CI workflows, traceability and policy documents.

DateKeys cifra datos de forma que solo puedan abrirse a partir de un instante
elegido. La condición temporal procede del beacon de aleatoriedad **Quicknet**
de drand: los datos se sellan con cifrado timelock hacia una ronda futura, y la
firma BLS de esa ronda, que drand publica cuando llega, es la llave. Todo lo que
se puede verificar localmente se verifica localmente; relays, cachés y APIs son
transportes no confiables.
> **Estado: v0.x, pre-estándar.** La especificación es un borrador y la API
> puede cambiar antes de v1.0.0. El código aún no ha pasado una revisión
> criptográfica externa (spec §75). No lo uses para secretos de alto valor.

## Una cápsula, en un dibujo
```text
.dkc = PRELUDE (16 B) || PUBLIC_HEADER (CBOR) || SEALED_CONTROL (age) || PAYLOAD_AGE (age, hasta EOF)
time_only: SEALED_CONTROL = age(tlock ronda R → CONTROL_CBOR)
Implement capsule format 2 of spec v0.9
The reference moves to the DateKeys Protocol Specification v0.9, approved
by its author on 29 September 2026. Encrypt writes capsule format 2 only;
Open and Inspect read formats 1 and 2, and a format 1 capsule keeps the
verdict v0.8.2 gave it.
Format 2 (spec §22, §29.1, §31, §39):
- VERSION in the PRELUDE is the capsule format, capsule.Format; any other
value is ERR_UNSUPPORTED_VERSION at step 2.
- CONTROL_CBOR has the schema version of its format. Version 2 adds key 6,
payload_length (8 bytes, big-endian, at most L_MAX = 2^53 - 2^46), and
key 7, padding (1 bloque256, 2 reforzado); it is 103 bytes without
extensions, whatever L.
- The payload is the content padded with zeros to P = rule(L). Step 17
checks the length and the zeros, and Open writes only the first L bytes.
- INNER_ACCESS_AGE holds exactly 16 X25519 stanzas: 1 to 16 credentials,
and a dummy in each slot left, in a uniformly random order.
Writer rules (spec §62.1): EncryptOptions.Length is required and the
source must deliver exactly that many bytes; recipients that are not
canonical or of low order are rejected (agewrap.CheckX25519Recipient);
self-checks of the header, the control, INNER_ACCESS_AGE and PAYLOAD_AGE.
The CLI measures its input, takes -padding and reports the format.
Test data: seven format 2 fixtures, padding vectors checked against
math/big, format 2 CBOR vectors, and the mutation corpus in both formats
with the 22 cases of the third list of spec §64, built without randomness
by sealing the fixtures again with their known keys and nonces. The
format 1 fixtures are kept byte for byte and never regenerated; the
differential corpus keeps its 1825 cases and adds a block per format 2
fixture. The spec copy loses its "to be implemented" markers, and the
READMEs, CHANGELOG, traceability and testdata/README.md follow v0.9.

credenciales hay, ni la longitud exacta L, ni los nombres de los ficheros ni
cuántos son, más allá de lo que acota P (spec §29.1, §39, §55.2). Ya abierta,

datekeys profile hash
Version constants: the specification and the module
- datekeys.SpecVersion ("0.8.2") names the specification the module
implements. A test ties it to the spec file, its title and
spec/README.md, and TestCatalogueMatchesSpec and the vector files use
it (testkit.SpecVersion now aliases it), so the vectors regenerate
unchanged.
- datekeys.Version() is the version of the module as the go command
recorded it. That is a tag, or for a binary built in a checkout the
pseudo-version of its commit (for example
v0.0.0-20260928105528-9ac9cd952f04), or (devel) when it is unknown, as
in tests or under a replace directive to a directory. It works as the
main module and as a dependency, whatever the module path, which it
reads from the root package.
- `datekeys version` (also -version and --version) prints both and the
Go toolchain.
- README.md and README.es.md explain the three versions (format,
specification, module) and what the code on main covers.
traceability §70 and CHANGELOG follow.

`encrypt` nunca usa la red. Cada `-in` es un fichero o una carpeta; una
carpeta da su nombre como primer segmento de sus rutas, como hace un
navegador, y se recorre sin seguir enlaces, tomando solo ficheros regulares y
dejando fuera `.DS_Store` , `Thumbs.db` , `desktop.ini` , `._*` y `__MACOSX` . Una
ruta o un texto que incumple una regla de spec §29.5 o §29.6 se rechaza,
nombrando la regla y el carácter. Los ficheros conservan su fecha de
modificación salvo con `-no-mtime` . El contenido se rellena con la regla
reforzado, o con bloque256 si se pide (spec §29.1).
`inspect` ejecuta solo las comprobaciones previas al desbloqueo (spec §63,
pasos 1 a 8): nunca pide un release ni usa secretos.
`decrypt` obtiene el release de relays públicos de drand y lo verifica
localmente. Los ficheros de una cápsula de formato 3 van a la carpeta nueva
`-out` , preparados dentro de ella y movidos a su sitio solo cuando todas las
comprobaciones han pasado (spec §56); una cápsula con solo un comentario no
crea la carpeta. Muestra los veredictos al principio y al final, y el autor
declarado, el comentario y las rutas como texto del creador que nadie ha
comprobado, cada línea tras el prefijo `│ ` y nunca más ancha que el terminal
(spec §29.7). Los formatos 1 y 2 siguen dando un fichero. Nunca se
sobrescriben ficheros de salida.

## Propiedades de seguridad y límites
- **Confidencialidad temporal** bajo el supuesto de umbral de drand. El
timelock de Quicknet **no es post-cuántico** : los ciphertexts guardados
durante años quedan expuestos a *harvest now, decrypt later* (spec §7.7, §53).
- **Sin confianza en servidores**: el perfil va pinneado en el binario, la ronda
se calcula localmente, los releases se verifican con BLS localmente y una
firma válida de otra ronda se rechaza (spec §13, §17, §51).
Spec v0.8.2: second-round corrections from the formal review
The second round of the formal review confirmed the nine corrections of
c57ed48 and asked for these, recorded in §76 as corrections 4 to 6 and
an editorial note:
- §72: an encoder MUST NOT write a registered extension in an object or
array it is not registered for; §54: a reader MUST NOT interpret the
data of a noncritical one it ignores for that reason. capsule.Encrypt
and accesskey.Encode take no Registry, so the application applies the
rule; their documentation and extension.Placement say so.
- §17 and §51 give the step-10 codes only for a directly supplied
release, as step 10 does; a network source discards a failing one at
step 9.
- Step 9 reports ERR_RELEASE_UNAVAILABLE and no other code, whatever the
failure of the source. provider/drand.Client keeps each relay's failure
as text only (errors.Join made a relay's ERR_ROUND_MISMATCH match with
errors.Is), and capsule.Open keeps only the text of a source error that
carries another code (a caller's source failing with
ERR_RELEASE_INVALID gave that code at step 9). A context that ended
stays detectable: Fetch now has a single failure path, so the canceled
and deadline cases are deterministic.
- TestExtensionPlacement covers the noncritical array of a .dkk: with
the object-blind extension.CheckNoncritical at step 9.a it fails.
- Editorial: §28.1 "analizan solo la cabecera age", one arrow at step 9,
two §76 introductions; §73 lines for release sources and placement.
- testdata/README.md says the corpus registers its extensions in both
arrays of every object; traceability, CHANGELOG and both READMEs
(integrity holds against whoever lacks the file keys, §27, §55.1)
follow. Spec dated 28 September 2026; new SHA-256 in spec/README.md.
No fixture or vector changes.

- **Integridad**: framing, cabecera, control y payload están autenticados
frente a quien no conoce las file keys: un cambio de un tercero hace fallar
la apertura (fixtures y corpus de mutaciones). Publicada la ronda,
cualquiera puede calcular la file key temporal, y cualquiera puede sellar
un control nuevo para una cabecera pública; quién puede escribir cada parte
y desde qué paso queda vinculada es el modelo de confianza de spec §27 y
§55.1.

- **Privacidad de metadatos**: hasta la fecha quedan ocultos la longitud
exacta del contenido, el número de credenciales, y los nombres, tamaños y
número de los ficheros, más allá de lo que acota el tamaño con relleno P; no
la fecha, la política de acceso, `capsule_id` ni las extensiones de la
cabecera (spec §55.2).
- **Extracción segura**: las rutas del head no pueden salir de la carpeta,
colisionar en Windows, macOS o Linux, esconder caracteres ni cambiar la
dirección del texto; las reglas usan tablas fijas de Unicode 18.0.0, nunca
las de la plataforma (spec §29.5, §29.6).
- **Sin autoría**: el autor declarado y el comentario son texto del creador
que no prueba nada, y esta versión no comprueba firmas ni sellos: sus
veredictos solo lo dicen, y nunca deciden la apertura (spec §29.3, §29.7,
§36.1). `time_and_key` añade una barrera de acceso, no una firma.

Implement capsule format 2 of spec v0.9
The reference moves to the DateKeys Protocol Specification v0.9, approved
by its author on 29 September 2026. Encrypt writes capsule format 2 only;
Open and Inspect read formats 1 and 2, and a format 1 capsule keeps the
verdict v0.8.2 gave it.
Format 2 (spec §22, §29.1, §31, §39):
- VERSION in the PRELUDE is the capsule format, capsule.Format; any other
value is ERR_UNSUPPORTED_VERSION at step 2.
- CONTROL_CBOR has the schema version of its format. Version 2 adds key 6,
payload_length (8 bytes, big-endian, at most L_MAX = 2^53 - 2^46), and
key 7, padding (1 bloque256, 2 reforzado); it is 103 bytes without
extensions, whatever L.
- The payload is the content padded with zeros to P = rule(L). Step 17
checks the length and the zeros, and Open writes only the first L bytes.
- INNER_ACCESS_AGE holds exactly 16 X25519 stanzas: 1 to 16 credentials,
and a dummy in each slot left, in a uniformly random order.
Writer rules (spec §62.1): EncryptOptions.Length is required and the
source must deliver exactly that many bytes; recipients that are not
canonical or of low order are rejected (agewrap.CheckX25519Recipient);
self-checks of the header, the control, INNER_ACCESS_AGE and PAYLOAD_AGE.
The CLI measures its input, takes -padding and reports the format.
Test data: seven format 2 fixtures, padding vectors checked against
math/big, format 2 CBOR vectors, and the mutation corpus in both formats
with the 22 cases of the third list of spec §64, built without randomness
by sealing the fixtures again with their known keys and nonces. The
format 1 fixtures are kept byte for byte and never regenerated; the
differential corpus keeps its 1825 cases and adds a block per format 2
fixture. The spec copy loses its "to be implemented" markers, and the
READMEs, CHANGELOG, traceability and testdata/README.md follow v0.9.

Implement capsule format 2 of spec v0.9
The reference moves to the DateKeys Protocol Specification v0.9, approved
by its author on 29 September 2026. Encrypt writes capsule format 2 only;
Open and Inspect read formats 1 and 2, and a format 1 capsule keeps the
verdict v0.8.2 gave it.
Format 2 (spec §22, §29.1, §31, §39):
- VERSION in the PRELUDE is the capsule format, capsule.Format; any other
value is ERR_UNSUPPORTED_VERSION at step 2.
- CONTROL_CBOR has the schema version of its format. Version 2 adds key 6,
payload_length (8 bytes, big-endian, at most L_MAX = 2^53 - 2^46), and
key 7, padding (1 bloque256, 2 reforzado); it is 103 bytes without
extensions, whatever L.
- The payload is the content padded with zeros to P = rule(L). Step 17
checks the length and the zeros, and Open writes only the first L bytes.
- INNER_ACCESS_AGE holds exactly 16 X25519 stanzas: 1 to 16 credentials,
and a dummy in each slot left, in a uniformly random order.
Writer rules (spec §62.1): EncryptOptions.Length is required and the
source must deliver exactly that many bytes; recipients that are not
canonical or of low order are rejected (agewrap.CheckX25519Recipient);
self-checks of the header, the control, INNER_ACCESS_AGE and PAYLOAD_AGE.
The CLI measures its input, takes -padding and reports the format.
Test data: seven format 2 fixtures, padding vectors checked against
math/big, format 2 CBOR vectors, and the mutation corpus in both formats
with the 22 cases of the third list of spec §64, built without randomness
by sealing the fixtures again with their known keys and nonces. The
format 1 fixtures are kept byte for byte and never regenerated; the
differential corpus keeps its 1825 cases and adds a block per format 2
fixture. The spec copy loses its "to be implemented" markers, and the
READMEs, CHANGELOG, traceability and testdata/README.md follow v0.9.
