Detailed example of swift MD5 encryption source code
Because MD5 encryption is irreversible, there is generally only MD5 encryption algorithm, but no MD5 decryption algorithm.
Create a sting + md5.swift string classification file (at the same time, create a bridge. H bridge file here and introduce this header file
#Import < commoncrypto / commondigest. H >, files required for MD5 encryption method)
1. Bridge. H bridging documents are as follows:
#ifndef bridge_h
#define bridge_h
#import <CommonCrypto/CommonDigest.h>
#endif /* bridge_h */
2. Sting + md5.swift string classification file is as follows
MD5 encryption algorithm is as follows
import Foundation
extension String {
var md5 : String{
let str = self.cString(using: String.Encoding.utf8)
let strLen = CC_LONG(self.lengthOfBytes(using: String.Encoding.utf8))
let digestLen = Int(CC_MD5_DIGEST_LENGTH)
let result = UnsafeMutablePointer<CUnsignedChar>.allocate(capacity: digestLen)
CC_MD5(str!, strLen, result)
let hash = NSMutableString()
for i in 0 ..< digestLen {
hash.appendFormat("%02x", result[i])
}
result.deinitialize()
return String(format: hash as String)
}
}
