Struct PdfEncryption 

pub struct PdfEncryption {
    pub user_password: String,
    pub owner_password: String,
    pub algorithm: PdfEncryptionAlgorithm,
    pub permissions: PdfPermissions,
}

PDF 加密配置。

使用构建器方法 with_algorithm 和 with_permissions 进行自定义。默认使用 AES-256 并授予所有权限。

Examples

use easypdf_core::crypto::{PdfEncryption, PdfEncryptionAlgorithm, PdfPermissions};

let enc = PdfEncryption::new("user", "owner");
assert_eq!(enc.algorithm, PdfEncryptionAlgorithm::Aes256);

let enc = PdfEncryption::new("u", "o")
    .with_algorithm(PdfEncryptionAlgorithm::Aes128)
    .with_permissions(PdfPermissions::PRINT | PdfPermissions::COPY);
assert_eq!(enc.algorithm, PdfEncryptionAlgorithm::Aes128);

Fields

user_password: String

打开和读取文档所需的密码。

owner_password: String

更改权限或移除加密所需的密码。

algorithm: PdfEncryptionAlgorithm

要使用的加密算法。

permissions: PdfPermissions

用户密码的权限标志。
