介绍
openssl rsautl 使用RSA算法签名，验证，加密，解密数据。
语法
openssl rsautl[-in file] [-out file] [-inkey file] [-pubin] [-certin] [-sign] [-verify] [-encrypt] [-decrypt]
[-pkcs] [-ssl] [-raw] [-hexdump] [-asn1parse]
-inkey file / -pubin 指定密钥文件，默认是私钥；如果指定-pubin，则表示是公钥。
-sign / -verify 签名和验证（a.txx文本文件的内容是“hello world”）
E:\OpenSSL\foo>openssl rsautl -sign -in a.txt -inkey rsa_pri_nopw.pem -out a.sig #签名 n Loading 'screen' into random state - done E:\OpenSSL\foo>openssl rsautl -verify -in a.sign -inkey rsa_pri_nopw.pem #私钥验证 Loading 'screen' into random state - done hello world E:\OpenSSL\foo>openssl rsautl -verify -in a.sign -pubin -inkey rsa_pub_nopw.pem #公钥验证 Loading 'screen' into random state - done hello world E:\OpenSSL\foo>openssl rsautl -verify -in a.sign -inkey demoCA\cacert.pem -certin #证书验证 Loading 'screen' into random state - done hello world
-encrypt / -decrypt 加解密
E:\OpenSSL\foo>openssl rsautl -encrypt -in a.txt -pubin -inkey rsa_pub_nopw.pem -out a.enc Loading 'screen' into random state - done E:\OpenSSL\foo>openssl rsautl -decrypt -in a.enc -inkey rsa_pri_nopw.pem Loading 'screen' into random state - done hello world
