File f = new File("..."); // exe文件路径 File f1 = new File("..."); // 生成的rar文件路径 FileInputStream fin = new FileInputStream(f); FileOutputStream fout = new FileOutputStream(f1); BufferedInputStream bin = new BufferedInputStream(fin); BufferedOutputStream bout = new BufferedOutputStream(fout); int in; do { in = bin.read(); if (in == -1) break; in ^= 0x88; bout.write(in); } while (true); bin.close(); fin.close(); bout.close(); fout.close();
如果你的exe是用EXE4J生成的可以使用e68a84e8a2ad62616964757a686964616f31333337383831位运算
