openssl命令

openssl dgst -verify pub.pem -sha256 -signature sign.txt file.txt  通过公钥pub.pem验证签名文件sign.txt和file.txt

openssl x509 -in new.crt -pubkey -noout > pubkey.pem 从证书new.crt提取公钥文件pubkey.pem

openssl base64 -in test.base64 -d -out text.bin 将base64编码文件test.base64转为二进制文件tetx.bin  需要手动在test.base64后添加换行符

openssl dgst -binary -sha256 -out hash.bin test.tar   计算test.tar包的hash值 (二进制格式)
openssl base64 -in hash.bin -out hash.base64 计算base64编码

对csr文件进行签名:

openssl smime -sign -binary -signer certificat.pem -inkey key.pem -in testCSRfile_to_sign.pem -out testCSRfile_smime.signed -nodetach

openssl smime -verify -noverify -in testCSRfile_smime.signed -pk7out -out testCSRfile_P7.signed

openssl pkcs7 -in testCSRfile_P7.signed -out testCSRfile_P7_DER.signed -outform der

mv testCSRfile_P7_DER.signed PKCS10_testCSRfile.data

openssl常用命令

ECC证书请求文件

openssl ecparam -name prime256v1 -genkey -out server-ecc.key 生成密钥
openssl req -new -key server-ecc.key -out server.csr 生成csr请求文件

从p7b格式证书链提取证书

openssl pkcs7 -inform der -in consol_p7_MP_ECC_256_18.p7b -out MP_ECC.p7b

openssl pkcs7 -print_certs -in MP_ECC.p7b -out MP_ECC.cer

 

验证证书链

 openssl verify -CAfile MP_RSA_2048_chain.cer -untrusted rsa_sec.cer submp.cer

MP_RSA_2048_chain二级证书链,有根证书和二级证书

rsa_sec.cer二级证书

submp.cer叶子证书

 

证书链验证证书

openssl verify -CAfile  cert.pem test.crt

cert.pem证书链

test.crt叶子证书

 

ECC证书签名验签

1 从证书test.cer中获取到公钥信息,将获取到的信息存为public_key.pem

openssl x509 -noout -pubkey -in test.cer

2 对t数据进行sha256签名,

testsign.txt待签名文件,

test.private私钥,

sha256.sign签名结果

openssl dgst -sign test.private -sha256 -out sha256.sign testsign.txt

3 验证签名

openssl dgst -verify public_key.pem -sha256 -signature sha256.sign testsign.txt

 

查看证书test.crt内容

openssl x509 -in ./test.crt -text 

 查看key

openssl rsa -in ./test.key -text

检测私钥一致性 

openssl rsa -in test.key -check

pem文件是用ASCLL(BASE64)编码的

DER文件是二进制编码

公钥经过CA签名后可以当作证书

 

合成证书链,证书格式需要转化为pem格式

openssl crl2pkcs7 -inform PEM -certfile rootca.crt -certfile second-platform-ca.crt  -certfile leaf.pem -outform PEM -out root1.p7b -nocrl

转化p7b文件

openssl pkcs7 -print_certs -in root1.p7b -out cert1.cer

验证证书链

openssl verify -CAfile cert1.cer fourth.pem

 

der转化pem
openssl x509 -inform der -in myserver.der -outform pem -out myserver.pem
pem转化der
openssl x509 -inform pem -in myserver.pem -outform der -out myserver.der
