C#とJAVA間で同じキーとなるパスワード ベースのキー派生機能 (PBKDF2) を実装する方法

PBKDF2WithHmacSHA1.java

public static void main(String[] args) throws Exception {
	char[] password = "Hello, World!!".toCharArray();
	byte[] salt = new byte[] {1, 2, 3, 4, 5, 6, 7, 8};
	SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
	KeySpec spec = new PBEKeySpec(password, salt, 65536, 128); // キーは128Bit
	SecretKey tmp = factory.generateSecret(spec);
	byte[] digest = tmp.getEncoded();
	for (byte d : digest) {
		System.out.print(String.format("%02x", d));
	}
	System.out.println();
	// 2adfe63d125ae48eb056893dd18bc643
