移动端越来越火了，我们在开发过程中，总会碰到要和移动端打交道的场景，比如androID和iOS的打交道。为了让数据交互更安全，我们需要对数据进行加密传输。

这篇文章给大家分享AES的加密和解密、AndroID和ios通用的AES加密算法、大家可以直接集成到自己的项目、服务器接口如果是用Java写的话、整个框架都完美了、如果是.NET编写的后台接口的话、得改造一下哦

IOS加密

/*加密方法*/ (Nsstring *)AES256EncryptWithPlainText:(Nsstring *)plain { NSData *plainText = [plain dataUsingEnCoding:NSUTF8StringEnCoding]; // ´key´ should be 32 bytes for AES256,will be null-padded otherwise char keyPtr[kCCKeySizeAES256 1]; // room for terminator (unused) bzero(keyPtr,sizeof(keyPtr)); // fill with zeroes (for padding)   NSUInteger dataLength = [plainText length]; size_t bufferSize = dataLength kCCBlockSizeAES128; voID *buffer = malloc(bufferSize); bzero(buffer,sizeof(buffer));  size_t numBytesEncrypted = 0;  CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt,kCCAlgorithmAES128,kCcoptionPKCS7padding,[[NSData AESKeyForPassword:PASSWORD] bytes],kCCKeySizeAES256,ivBuff /* initialization vector (optional) */,[plainText bytes],dataLength,/* input */           buffer,bufferSize,/* output */           &numBytesEncrypted); if (cryptStatus == kCCSuccess) {  NSData *encryptData = [NSData dataWithBytesNocopy:buffer length:numBytesEncrypted];  return [encryptData base64EnCoding]; }  free(buffer); //free the buffer; return nil;}

IOS解密

/*解密方法*/ (Nsstring *)AES256DecryptWithCiphertext:(Nsstring *)ciphertexts{  NSData *cipherData = [NSData dataWithBase64EncodedString:ciphertexts]; // ´key´ should be 32 bytes for AES256,sizeof(keyPtr)); // fill with zeroes (for padding)   NSUInteger dataLength = [cipherData length];  size_t bufferSize = dataLength kCCBlockSizeAES128; voID *buffer = malloc(bufferSize);   size_t numBytesDecrypted = 0; CCCryptorStatus cryptStatus = CCCrypt(kCCDecrypt,ivBuff,/* initialization vector (optional) */           [cipherData bytes],/* output */           &numBytesDecrypted);  if (cryptStatus == kCCSuccess) {  NSData *encryptData = [NSData dataWithBytesNocopy:buffer length:numBytesDecrypted];  return [[[Nsstring alloc] initWithData:encryptData enCoding:NSUTF8StringEnCoding] init]; }  free(buffer); //free the buffer; return nil;}

AndroID加密

private byte[] encrypt(String cmp,SecretKey sk,IvParameterSpec IV,byte[] msg) { try {  Cipher c = Cipher.getInstance(cmp);  c.init(Cipher.ENCRYPT_MODE,sk,IV);  return c.doFinal(msg); } catch (NoSuchAlgorithmException nSAE) {  Log.e("AESdemo","no cipher getinstance support for " cmp); } catch (NoSuchpaddingException nspe) {  Log.e("AESdemo","no cipher getinstance support for padding " cmp); } catch (InvalIDKeyException e) {  Log.e("AESdemo","invalID key exception"); } catch (InvalIDAlgorithmParameterException e) {  Log.e("AESdemo","invalID algorithm parameter exception"); } catch (IllegalBlockSizeException e) {  Log.e("AESdemo","illegal block size exception"); } catch (BadpaddingException e) {  Log.e("AESdemo","bad padding exception"); } return null;}

AndroID解密

private byte[] decrypt(String cmp,byte[] ciphertext) { try {  Cipher c = Cipher.getInstance(cmp);  c.init(Cipher.DECRYPT_MODE,IV);  return c.doFinal(ciphertext); } catch (NoSuchAlgorithmException nSAE) {  Log.e("AESdemo","bad padding exception");  e.printstacktrace(); } return null;}
