Description: Elgamal签名是基于离散对数问题的，首先选择p，g计算出B，作为公钥（p，g，B），在选择一个a作为私钥，给出明文m，对明文机型加密，计算出x，y，得到签名，接收方就可以进行验证。签名过程中必须使用Hash函数，否则的话容易受到存在性伪造攻击，并且签名长度是明文长度的二倍。

Description: 软件是bouncycastle组织开发的软件包，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。可以作为研究、学习信息安全中的密码学设计与实现技术。在原版的基础上进行一些改进，对文件加密、解密的时候要频繁的IO加一个缓冲区，RSA私钥积存的时候可以按PKCS8形式，再经BASE64编码保存。-Software development organization is bouncycastle package, including DES_CBC Algorithm, RSA algorithm implementation (including: key generation, public key encryption and private decryption, digital signature and signature verification), the realization of digital envelope using the envelope to achieve digital large file encryption and decryption. 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.

Description: Openssl 是一个功能丰富且自包含的开源安全工具箱。它提供的主要功能有：
SSL 协议实现(包括SSLv2、SSLv3 和TLSv1)、大量软算法(对称/非对称/摘要)、
大数运算、非对称算法密钥生成、ASN.1 编解码库、证书请求(PKCS10)编解码、
数字证书编解码、CRL 编解码、OCSP 协议、数字证书验证、PKCS7 标准实现
和PKCS12 个人数字证书格式实现等功能。
Openssl 采用C语言作为开发语言，这使得它具有优秀的跨平台性能。Openssl
支持Linux、UNIX、windows、Mac 等平台。openssl 目前最新的版本是0.9.8e.
OpenSSL 整个软件包大概可以分成三个主要的功能部分：密码算法库、SSL 协
议库以及应用程序。OpenSSL 的目录结构自然也是围绕这三个功能部分进行规
划的。-Openssl is a feature-rich, self-contained open-source security toolkit. It provides the main functions are:
SSL protocol (including SSLv2, SSLv3 and TLSv1), a large number of software algorithm (symmetric/asymmetric/summary),
Operation of large numbers, asymmetric key generation algorithm, ASN.1 decoding library, certificate request (PKCS10) codec,
Encoding and decoding digital certificates, CRL codec, OCSP protocol, digital certificates, PKCS7 standard to achieve
And PKCS12 format to achieve personal digital certificate capabilities.
Openssl using C language as a development language, which makes it cross-platform with excellent performance. Openssl
Support for Linux, UNIX, windows, Mac and other platforms. openssl latest version is 0.9.8e.
OpenSSL about the whole package can be divided into three main functional components: cryptographic algorithm library, SSL Association
Proposed library and applications. OpenSSL is the directory structure of the natural features around the Platform: |
