加密解密 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
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。 ...
加密解密 RSA ( Rivest Shamir Adleman )is crypthograph system that used to give a secret information and digit
RSA ( Rivest Shamir Adleman )is crypthograph system that used to give a secret information and digital signature . Its security based on Integer Factorization Problem (IFP). RSA uses an asymetric key. RSA was created by Rivest, Shamir, and Adleman in 1977. Every user have a pair of key, public key a ...
