Enkripsi String ke MD5 pada Java Android


Yang ingin mencoba mengubah String kedalam bentuk enkripsi MD5, bisa menggunakan fungsi ini

public String md5(String s) {
		try {
			// Create MD5 Hash
			MessageDigest digest = java.security.MessageDigest
					.getInstance("MD5");
			digest.update(s.getBytes());
			byte messageDigest[] = digest.digest();

			// Create Hex String
			StringBuffer hexString = new StringBuffer();
			for (int i = 0; i < messageDigest.length; i++)
				hexString.append(Integer.toHexString(0xFF & messageDigest[i]));
			return hexString.toString();

		} catch (NoSuchAlgorithmException e) {
			e.printStackTrace();
		}
		return "";
	}

Contoh kode untuk konversi string ke MD5 :

String StringAwal = "hello";
String StringHasil = md5(StringAwal);
//hasilnya yang akan muncul : 5d41402abc4b2a76b9719d911017c592

jangan lupa tambahkan library berikut :

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
