Android、iOS和Java通用的AES128加密解密示例代码

前言

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, will be null-padded otherwise char keyPtr[kCCKeySizeAES256 1]; // room for terminator (unused) bzero(keyPtr, 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, kCCAlgorithmAES128, kCCOptionPKCS7Padding,           [[NSData AESKeyForPassword:PASSWORD] bytes], kCCKeySizeAES256,            ivBuff ,/* initialization vector (optional) */           [cipherData bytes], dataLength, /* input */           buffer, bufferSize, /* 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, SecretKey sk, IvParameterSpec IV,   byte[] ciphertext) { try {  Cipher c = Cipher.getInstance(cmp);  c.init(Cipher.DECRYPT_MODE, sk, IV);  return c.doFinal(ciphertext); } 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");  e.printStackTrace(); } return null;}
