How do I properly convert this SHA256 encryption function in PHP based off this Swift code?-CodePudding

I have the following code in Swift (iOS) to do some basic data encryption:

import Foundation
import CommonCrypto

// ... 

static func sha256(_ data: Data) -> Data? {
    guard let res = NSMutableData(length: Int(CC_SHA256_DIGEST_LENGTH)) else { return nil }
    CC_SHA256((data as NSData).bytes, CC_LONG(data.count), res.mutableBytes.assumingMemoryBound(to: UInt8.self))
    return res as Data
}

I'm unfamiliar with encryption in PHP but need this simple function converted for a small project.

CodePudding user response：

For data encryption in PHP, you may use the hash function.

Just pass 'sha256' as the first parameter if you want to use sha256 hashing algorithm

Assuming that $data contains the data , then

<?php 

echo hash('sha256', $data); 

?>
