crypto.DEFAULT_ENCODING
稳定性: 0 - 弃用
用于可以采用字符串或缓冲区的函数的默认编码。
默认值为 'buffer'，这使得方法默认为 Buffer 对象。
提供 crypto.DEFAULT_ENCODING 机制是为了与期望 'latin1' 作为默认编码的遗留程序向后兼容。
新应用程序应该期望默认值为 'buffer'。
此属性已弃用。
Stability: 0 - Deprecated
The default encoding to use for functions that can take either strings
or buffers. The default value is 'buffer', which makes methods
default to Buffer objects.
The crypto.DEFAULT_ENCODING mechanism is provided for backward compatibility
with legacy programs that expect 'latin1' to be the default encoding.
New applications should expect the default to be 'buffer'.
This property is deprecated.
