对原生框架 CommonDigest 的封装，提高开发效率

XZDataDigester

Example

To run the example project, clone the repo, and run pod install from the Pods directory first.

Requirements

iOS 11.0, Xcode 14.0

Installation

XZDataDigester is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'XZDataDigester'

功能特性

支持 md2、md4、md5、sha1、sha224、sha256、sha384、sha512 摘要算法。

let md5 = XZDataDigester.digest(data, algorithm: .MD5, hexEncoding: .uppercase)
let sha1 = XZDataDigester.digest(data, algorithm: .SHA1, hexEncoding: .uppercase)
let sha256 = XZDataDigester.digest(data, algorithm: .SHA256, hexEncoding: .uppercase)

// 对于 md5 或 sha1 有更简便的拓展方法
let md5 = string.md5
let sha1 = string.sha1

支持多数据合并计算摘要。

let digester = XZDataDigester.init(.MD5);

let array = ["1", "2", "3"]
for item in array {
    digester.add(item)
}
let result = digester.digest() as NSData

let md5 = result.hexEncodedString

可以用来计算大文件的摘要。

let digester = XZDataDigester.init(.MD5);

let file = ...
while !file.EOF {
    let data = file.read() // 每次读取一小部分数据，避免占用太多内存
    digester.add(data)
}
let result = digester.digest() as NSData

let md5 = result.hexEncodedString
