RSA加密算法，界面操作，可以很方便的对文件的内容进行加密，而且为了能加密更长的内容，算法中采用了分段加密的手段。其算法步骤如下：1. 读取公钥e和n，作加密之用。 2. 从DecText中读取一大段明文，转化成明文字节数组Byte[]。 3. 再把Byte[]分成若干小段明文字节数组sectByt

-RSA encryption algorithm, interface operation, it is easy to encrypt the contents of the documents, and longer in order to encrypt the contents of the sub-algorithm used in encryption means. The algorithm steps are as follows: 1. To read the public key e and n, used for encryption. 2. DecText read from a paragraph expressly, explicitly into byte array Byte []. 3. Then Byte [] into byte array express a number of short sectByt
