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

Can be used as research, study of information security design and implementation of cryptographic technology. On the basis of the original number of improvements, file encryption, decryption time to frequent the IO plus a buffer, RSA private key can PKCS8 accumulated when the form and then saved by the BASE64 encoding.
