3_3des
- 三重DES增加了密钥长度,由56位增加到112或168位,有更高的安全性,而且在新一代因特网安全标准IPSEC协议集中已将DES作为加密标准。-3DES key length increased from 56 to 112 or 168. have higher security, and the new generation of Internet security standards IPSEC agreement has been concentrated DES encryption
2_des
- DES算法把64位的明文输入块变为64位的密文输出块,它所使用的密钥也是64位,首先,DES把输入的64位数据块按位重新组合,并把输出分为L0、 R0两部分,每部分各长32位,并进行前后置换(输入的第58位换到第一位,第50位换到第2位,依此类推,最后一位是原来的第7位),最终由L0输出左 32位,R0输出右32位,根据这个法则经过16次迭代运算后,得到L16、R16,将此作为输入,进行与初始置换相反的逆置换,即得到密文输出。-DES algorithm combines the 64 expr
7_Rsa
- RSA公钥加密算法基于大整数因式分解困难这样的事实。 选择两个素数,p,q。(一般p,q选择很大的数) 然后计算 z=p*q f=(p-1)(q-1) 选择一个n,使gcd(n,f)=1(gcd代表greatest common divider,一般n也选择一个素数), n和z就作为公钥。 选择一个s,0<s<f,满足n*s % f=1,s就作为私钥。-RSA public key encryption algorithm based on the integer fa
