【筆記】java與python HmacSHA256加密代碼

java

    public static String sign(String content,String appkey) {

        String result = null;
        try {
            Mac hmacSha256 = Mac.getInstance("HmacSHA256");
            byte[] keyBytes = appkey.getBytes("UTF-8");
            hmacSha256.init(new SecretKeySpec(keyBytes, 0, keyBytes.length, "HmacSHA256"));

            byte[] hmacSha256Bytes = hmacSha256.doFinal(content.getBytes("UTF-8"));
            result = new String(Base64.encodeBase64(hmacSha256Bytes), "UTF-8");
        } catch (Exception e) {
            e.printStackTrace();
        }
