DSA算法还是比较少的,这个是基于DSA算法认证的加密算法库~-DSA algorithm is relatively small, the DSA is based on the encryption algorithm authentication algorithm library ~

C＋＋实现的数字签名DSA算法，不够完善，存在一点外部函数调用的问题

通过实现数字签名算法（DSA），加深对数字签名算法的理解，同时学习Hash算法的实现。 1）利用C\C++语言实现DSA算法。 2）DSA中的Hash函数采用SHA算法。 -By implementing the Digital Signature Algorithm (DSA), a better understanding of the digital signature algorithm, while learning to achieve Hash algorithm. 1
