Class LoginCrypto

java.lang.Object

client.LoginCrypto

public class LoginCrypto
extends Object

登入驗證所需的密碼雜湊與輔助加密工具類別。

提供三類靜態功能：

• SHA-1 雜湊（hexSha1）與加鹽 SHA-512 雜湊（makeSaltedSha512Hash） 及對應的校驗方法，供帳號密碼比對與新密碼儲存使用。
• 16 位元組隨機鹽值生成（makeSalt）以及舊式對稱混淆方法 （rand_s/rand_r），與 LoginCryptoLegacy 協同 支援多版本密碼格式升級。
• Asiasoft Passport 格式帳號號碼產生器（Generate_13DigitAsiasoftPassport）。

本類別的方法由 MapleCharacterUtil.Change_SecondPassword(int, String, String) 及 MapleClient 登入流程呼叫；不持有任何狀態（全靜態）。 雜湊演算法均以 UTF-8 編碼輸入字串，輸出為小寫十六進位字串（透過 HexTool）。
