Openssl smime命令

一、简介

S/MIME工具，用于处理S/MIME邮件，它能加密、解密、签名和验证S/MIME消息

二、语法

openssl smime [-encrypt] [-decrypt] [-sign] [-verify] [-pk7out] [-nointern] [-nosigs] [-noverify] [-nocerts] [ -nodetach] [-noattr] [-binary] [-in file] [-inform SMIME|PEM|DER] [-certfile file] [-signer file] [-recip file] [-passin arg] [-inkey file] [-keyform PEM |ENGINE] [-out file] [-outform SMIME|PEM|DER] [-content file] [-to addr] [-from ad] [-subject s] [-text] [-CApath directory] [-CAfile filename] [-crl_check] [-crl_check_all] [-indef] [-noindef] [-stream] [-rand file(s)] [-md digest] [cert.pem…] [-des] [-des3] [-rc2-] [-rc2-] [-rc2-]

               load the file (or the files in the directory) into
               the random number generator
cert.pem       recipient certificate(s) for encryption

三、实例

1、进行数字签名

1）包含证书和原文信息

openssl smime -sign -inkey prikey.pem -signer certself.pem -in install.log -out install_sign.msg

2）不包含证书信息

openssl smime -sign -inkey prikey.pem -signer certself.pem -passin pass:"123456" –nocerts -in install.log -out install_sign.msg

3）不包含原文

openssl smime -sign -inkey prikey.pem -signer certself.pem -passin pass:"123456" -nodetach -in install.log -out install_sign.msg

2、进行签名验证

1）包含证书和原文信息

openssl smime -verify -CAfile certself.pem -in install_sign.msg -out install_verify.log 

2）不验证签名者证书信息

openssl smime -verify -noverify -CAfile certself.pem -signer certself.pem -in text_sign.msg -out text_verify.log

3）不包含原文

openssl smime -verify -nodetach -CAfile certself.pem -signer certself.pem -in text_sign.msg -out text_verify.log

3、进行数字信封加密

openssl smime -encrypt -in install.log -out install_evp.enc certself.pem

4、进行数字信封解密

openssl smime -decrypt -in install_evp.enc -out install_ope.log -inkey prikey.pem

5、smime格式与pkcs#7格式的互转

openssl smime -in text_sign.msg -pk7out -out test_pkcs.pem

openssl pkcs7 -in test_pkcs.pem -text

6、对一个现存的消息添加一个签名者

openssl smime -resign -in mail.msg -signer newsign.pem -out mail2.msg
