DirnameKey

Struct DirnameKey 

Source
pub struct DirnameKey(/* private fields */);
Expand description

目录名加密密钥。

独立类型而不是裸 SecretKey:这样类型系统会阻止把它误用成文件密钥 或反之。两者都是 32 字节,混用不会编译报错但会产出解不开的数据。

Implementations§

Source§

impl DirnameKey

Source

pub fn derive(kek: &Kek, vault_salt: &[u8; 16]) -> Self

从 KEK 与 vault salt 派生。

同一个 vault 内必须得到同一个密钥,否则同一棵树里的目录名会用 不同密钥加密,解开时部分目录变成乱码。这由 vault_salt 保证—— 它在 vault 内是固定的。
