·1.创建加密密钥
//默认生成2048 bit 长度,可以添加 1024 bit
$openssl genrsa -out private.pem
·2.通过私钥生成公钥
$openssl rsa -in private.pem -pubout -out public.pem
·测试加密解密
·创建txt文件
$vi rsaT.txt
··私钥加密->公钥解密
//加密
$openssl rsautl -sign -in rsaT.txt -inkey private.pem -out decRsaT.txt
//解密
$openssl rsautl -verify -in decRsaT.txt -inkey public.pem -pubin -out publicVerifyTestRsa.txt
··公钥加密->私钥解密
//加密
$openssl rsautl -encrypt -in rsaT.txt -inkey public.pem -pubin -out encRsaT.txt
//解密
$openssl rsautl -decrypt -in encRsaT.txt -inkey private.pem -out decRsaT.txt
