Description: 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sectByte[]。 4. 使用e和n对所有的sectByte[]进行加密，并合成一大段密文,添加到EncText。 5. 读取下一大段明文，若明文为空，完成加密；否则转2-RSA encryption algorithm, interface operation, it is convenient to the contents of the documents for encryption, but in order to longer content encryption algorithm used in the sub-encryption tools. The algorithm steps are as follows : 1. Read public key e and n, for encryption purposes. 2. DecText from reading a big specifically, into an express byte array Byte []. 3. Byte [] then divided into pieces expressly sectByte byte [] array. 4. The use of e and n of all sectByte [] encryption and synthesis of a large dense text to be added EncText. 5. The next major reading of the express, if expressly for the space, complete encryption; Otherwise turn 2 Platform: |

Description: 说明：
1、里面有什么：
1.1、org.bouncycastle.*下的所有软件是bouncycastle组织开发的软件包
1.2、org.infosecurity.*下的软件包括：
DES_CBC算法的实现
RSA算法的实现（包括：密钥生成、公钥加密和私钥解密、数字签名及签名验证）
数字信封的实现
利用数字信封实现大文件的加密、解密。
2、有什么用：
2.1 研究、学习信息安全中的密码学设计与实现技术。
2.2 当然如果大家觉得在其它地方用的上，我会觉得很高兴的。
3、还有什么改进：
3.1 对文件加密、解密的时候要频繁的IO，如果加一个缓冲区，比如10K、50K等，
只有缓冲区满了才写入DISK这样将提高效率。
3.2 RSA私钥积存的时候可以按PKCS8形式，再经BASE64编码保存比较好。-Note : 1, mean there : 1.1, org.bouncycastle .* of all software development organizations is bouncycastle package 1.2, org.infosecurity .* The software includes : DES_CBC algorithm to achieve the realization of the RSA algorithm (including : key generation, public key and private key encryption decryption, digital signatures and signature verification), the realization of digital envelope using digital envelope realize document encryption, decryption. Two, what is the use of : 2.1, learning the information security cryptography design and technology. 2.2 Of course, if you think in the other parts, I feel very happy. Three, what is there for improvement : 3.1 pairs of file encryption, decryption, and the time to frequent the IO, plus a buffer, such as 10K, 50K, the only buffer is needed for Platform: |
