基于原生 CommonCrypto 框架进行的二次封装，将 AES、DES、CAST 等对称加密函数，封装成易于使用的面向对象的版本。
在示例项目中，提供了完整的使用示例，也可用来体验 XZDataCryptor 提供的对称加密功能。
To run the example project, clone the repo, and run pod install from the Pods directory first.
iOS 11.0, Xcode 14.0
XZDataCryptor is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'XZDataCryptor'XZDataCryptor 使用 OC 编写，但是也为 Swift 进行了 API 命名优化，更易方便使用。
1、支持的加密算法
- AES 根据密钥长度自动使用 AES128/AES192/AES256
- DES
- 3DES
- CAST
- RC2
- RC4
- Blowfish
let algorithm = XZDataCryptor.Algorithm.AES(key: "key", vector: "vector")- AES/DES 加密
// 默认使用 CBC 模式、PKCS7 填充
let result = try? XZDataCryptor.AES(data, operation: .encrypt, key: "key", vector: "vector")
let result = try? XZDataCryptor.DES(data, operation: .decrypt, key: "key", vector: "vector")
// 使用 ECB 模式
let result = try? XZDataCryptor.AES(data, operation: .encrypt, key: "key", vector: nil, mode: .ECB, padding: .PKCS7)
let result = try? XZDataCryptor.DES(data, operation: .decrypt, key: "key", vector: nil, mode: .ECB, padding: .PKCS7)- 其它加密算法
let result = try? XZDataCryptor.encrypt(data, algorithm: .CAST(key: "key", vector: "vector"), mode: .CBC, padding: .PKCS7)
let result = try? XZDataCryptor.decrypt(data, algorithm: .CAST(key: "key", vector: "vector"), mode: .CBC, padding: .PKCS7)- 分段加密
let datas: [Data] // 分段的数据
let algorithm = XZDataCryptor.Algorithm.AES(key: "key", vector: "vector") // 这里可以是其他算法
let cryptor = XZDataCryptor.init(operation: .encrypt, algorithm: algorithm, mode: .CBC, padding: .PKCS7)
var result = Data()
do {
for data in datas {
let tmp = try cryptor.crypt(data)
result += tmp
}
result += try cryptor.final()
} catch {
print("Error: \(error)")
}
print("\(result.base64EncodedString())")Xezun, developer@xezun.com
