在Android中生成HMAC-SHA1 签名

How to generate HMAC-SHA1 Signature in Android?

base为public key

key为private key

返回String为加密后字符串数据

public static String hmacSha1(String base, String key) throws NoSuchAlgorithmException, InvalidKeyException {

String type = "HmacSHA1";

SecretKeySpec secret = new SecretKeySpec(key.getBytes(), type);

Mac mac = Mac.getInstance(type);

mac.init(secret);

byte[] digest = mac.doFinal(base.getBytes());

return Base64.encodeToString(digest, Base64.DEFAULT);

}//end function hmacSha1( )
