Currently including `zh_CN` and `es` which both have very high completion ratios. Others will be added once they reach a significant percentage too. These RST files will be used by godot-docs in place of its `classes` folder after we sync with https://github.com/godotengine/godot-docs/pull/5458. The update workflow is manual for now (example for `zh_CN`): - Build `godotengine/godot` in the branch we currently track (now `3.x`) - Run `godot --doctool -l zh_CN` - Run `cd doc && make rst LANGARG=zh_CN` - Copy `doc/_build/rst/*` to `classes/zh_CN/` here - Make sure to have `classes/zh_CN/index.rst` copied from `docs/classes`

==============

**Inherits:** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

Contexto para calcular los hashes criptográficos en múltiples iteraciones.

|
Descripción
|
|
----------------------
|
|
|
|
La clase HashingContext proporciona una interfaz para computar hashes criptográficos en múltiples iteraciones. Esto es útil, por ejemplo, cuando se calculan hashes de archivos grandes (para no tener que cargarlos todos en la memoria), flujos de red y flujos de datos en general (para no tener que mantener búferes).
|
|
|
|
El :ref:`HashType<enum_HashingContext_HashType>` enum muestra los algoritmos de hash soportados.
|

|

|
|
|
|
const TAMANO_PORCION = 1024
|
|
|
|
func hash_archivo(ruta):
|
|
var contexto = HashingContext.new()
|
|
var archivo = File.new()
|
|
# Empieza un contexto SHA-256
|
|
contexto.start(HashingContext.HASH_SHA256)
|
|
# Comprueba que el archivo existe.
|
|
if not archivo.file_exists(ruta):
|
|
return
|
|
# Abre el archivo a hashear.
|
|
archivo.open(ruta, File.READ)
|
|
# Actualiza el contexto despues de leer cada porción.
|
|
while not archivo.eof_reached():
|
|
contexto.update(file.get_buffer(TAMANO_PORCION))
|
|
# Obtiene el hash computado.
|
|
var resultado = contexto.finish()
|
|
# Imprime el resultado como una string hexadecimal y array.
|
|
printt(resultado.hex_encode(), Array(resultado))
