一、简介

生成RSA私有密钥

 

二、语法

openssl  genrsa [-out filename] [-passout arg] [-f4] [-3] [-rand file(s)] [-engine id] [numbits] [-des] [-des3] [-idea]

选项

usage: genrsa [args] [numbits] -des            encrypt the generated key with DES in cbc mode -des3           encrypt the generated key with DES in ede cbc mode (168 bit key) -idea           encrypt the generated key with IDEA in cbc mode -seed                 encrypt PEM output with cbc seed -aes128, -aes192, -aes256                 encrypt PEM output with cbc aes -camellia128, -camellia192, -camellia256                 encrypt PEM output with cbc camellia -out file       output the key to 'file -passout arg    output file pass phrase source -f4             use F4 (0x10001) for the E value -3              use 3 for the E value -engine e       use engine e, possibly a hardware device. -rand file:file:...                 load the file (or the files in the directory) into                 the random number generator

 

三、实例

1、生成1024位rsa私钥，采用des算法加密

openssl genrsa -des -passout pass:"1234546" -out prikey.pem 1024

 

2、根据私钥生成公钥

openssl rsa -in prikey.pem -out pubkey.pem -pubout
