JAVA -HMACSHA256

HI i need t开发者_如何学Pythono perform HMACSHA256 encryption please help me;

 sha256 = MessageDigest.getInstance("HMACSHA1"); //I get exception in this line (No algorithm found)

---

Mac hmacSha256 = Mac.getInstance("hmacSHA256");

Hashing and Mac-ing are not encryption.

try:

sha256 = MessageDigest.getInstance("HMAC-SHA1");
