    I have soft ask key to open, after decompile i see it use algorithm AES (below).

    Input data includes the following two strings

    string 1: AEJ4J16nY7VAZ42xQl84pw==
    String 2: PJwyQs1x2aZL0Xck/Ixre+IOSe+W21JtCgKGDm5IHhE=

    Key generation algorithm
    PHP:
    Select All
    public static string smethod_0(string string_0string string_1)
    {
        
    RijndaelManaged managed Delegate2049.smethod_0();
        
    MD5CryptoServiceProvider provider Delegate2039.smethod_0();
        
    string str2 "";
        try
        {
            
    byte[] buffer2 = new byte[0x20];
            
    byte[] buffer3 Delegate2058.smethod_0(providerDelegate2045.smethod_0(Delegate2048.smethod_0(), string_1));
            
    Delegate2053.smethod_0(buffer30buffer200x10);
            
    Delegate2053.smethod_0(buffer30buffer2150x10);
            
    Delegate2046.smethod_0(managedbuffer2);
            
    Delegate2036.smethod_0(managedCipherMode.ECB);
            
    ICryptoTransform transform Delegate2610.smethod_0(managed);
            
    byte[] buffer Delegate2045.smethod_0(Delegate2048.smethod_0(), string_0);
            
    str2 Delegate1837.smethod_0(Delegate2043.smethod_0(transformbuffer0buffer.Length));
        }
        catch (
    Exception exception1)
        {
            
    Delegate2071.smethod_0(exception1);
            
    Exception exception exception1;
            
    GClass20.smethod_2(Delegate53.smethod_0("Ch\x00fa \x00fd AES Encrypt bị lỗi : "Delegate68.smethod_0(exception)), "Th\x00f4ng b\x00e1o");
            
    Delegate119.smethod_0();
        }
        return 
    str2;
    }
    Who can help me crack this key ?

    TKs so much!
