Java MessageDigest sha1 wrong result
0
Example input: 0200302007 (a hex value)
byte utf8 = "0200302007".getBytes("UTF-8");
MessageDigest messageDigest = MessageDigest.getInstance("SHA-1");
messageDigest.update(utf8);
return messageDigest.digest();
SHA1 expected result is: 129DB11A3DEAFDAD52BC7CBEB20FD7947F31B7B6
But the above code give results in:
ECC933969191424B4B67F3FA29C0E103471EC311
Why is that?

You need to specify the input value correctly:
byte utf8 = {0x2, 0x0, 0x30, 0x20, 0x7};
