RSA加长分段解密算法，界面操作。算法步骤如下：1. 读取私钥d和n，作解密之用。 2. 从EncText中读取一大段密文，再把该大段密文分成若干小段密文。 3. 使用d和n把所有小段密文进行解密成对应的小段密文sectByte[]，再合成一大段明文字节数组Byte[]，并转化成大段明文添加到Dec

-RSA decryption algorithm extended sub-interface operation. Algorithm steps are as follows: 1. To read the private key d and n, for decryption purposes. 2. EncText read from a large segment ciphertext, then the large segment is divided into several small pieces of ciphertext ciphertext. 3. The use of all sub-paragraph d, and n decrypt the ciphertext into the corresponding bits of ciphertext sectByte [], and then synthesized a large section explicitly byte array Byte [], and transformed into National Cheng Kung University in paragraph explicitly added to the Dec
