SHA256
- In cryptography, SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512) designed by the National Security Agency (NSA) and published in 2001 by the NIST as a U.S. Federal Information Processing Standard. SHA stands for Se
SHA
- SHA-1 produces a message digest based on principles similar to those used by Ronald L. Rivest of MIT in the design of the MD4 and MD5 message digest algorithms, but has a more conservative design.SHA-2 is a set of cryptographic hash functions (SHA-22
BLAKE2-master
- BLAKE2 are cryptographic hash functions based on Dan Bernstein s Cha stream cipher, but a permuted copy of the input block, XORed with some round constants, is added before each Cha round. Like SHA-2, there are two variants differing in the word size
md5
- 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
数字签名实验
- DSA签名程序和DSA验证程序。 签名程序流程： a. 读入字符串（从屏幕或文本文件中），字符串内容应包含自己的学号或姓名； b. 计算该字符串的SHA-1值； c. 生成DSA密钥对（利用dsa_make_key）； d. 利用dsa_export函数导出所生成的DSA密钥对的公钥，并保存到文件中（dsa_key.pub），供验证程序使用； e. 对第2步产生的SHA-1值进行签名，保存签名到文件中（signature.txt）(DSA signatures and DSA val
