任何用于验证 ECDSA prime256v1 证书和私钥匹配的 openssl 命令行？

Question

我现在正在测试 hyperledger/fabric/core/comm/testdata/certs/generate.go 以获得 ECDSA prime256v1 证书（Org1-cert.pem）和私钥（Org1-key.pem）。我想使用 openssl 命令行来测试 Org1-cert.pem 是否对 Org1-key.pem 进行数学运算，但不知道如何？任何帮助表示赞赏。我已经使用了该命令，但结果不匹配。

# openssl x509 -pubkey -in Org1-cert.pem -noout | openssl md5

（标准输入）= 4f8782bbec9d258553f0c0c7c6879fef

# openssl pkey -pubout -in Org1-key.pem | openssl md5

（标准输入）= 98c3ec3c2971648f2721915ff7e80479

更多关于 Org1-cert.pem 和 Org1-key.pem 的信息如下：

Answer 1

您可以使用 OpenSSL 验证证书与任何受支持的密钥（包括 ECDSA prime256v1 密钥）是否匹配。

此命令将从证书中获取公钥：

openssl x509 -noout -pubkey -in Org1-cert.pem

此命令将从密钥中获取公钥：

openssl pkey -pubout -in Org1-key.pem

您可以直观地比较它们...

或者，您可以使用 Bash 自动比较任何证书和密钥，如下所示：

1. 创建一个名为verify-cert-key的脚本：

   #!/usr/bin/env bash
   certFile="${1}"
   keyFile="${2}"
   certPubKey="$(openssl x509 -noout -pubkey -in "${certFile}")"
   keyPubKey="$(openssl pkey -pubout -in "${keyFile}")"
   if [[ "${certPubKey}" == "${keyPubKey}" ]]
   then
     echo "PASS: key and cert match"
   else
     echo "FAIL: key and cert DO NOT match"
   fi
   

2. 使脚本可执行：

   chmod +x verify-cert-key
   

3. 运行：

   ./verify-cert-key Org1-cert.pem Org1-key.pem
   

警告：macOS Sierra 上的 openssl 没有 pkey

在 macOS Sierra 上，脚本可能会说“失败：密钥和证书不匹配”，即使它们确实如此。

验证是否缺少 pkey：

openssl pkey -in

如果丢失，您将看到：

openssl:Error: 'pkey' is an invalid command.

其次是来自 OpenSSL 的大量其他使用摘要输出。

您可能还会看到“openssl:Error: 'pkey' is an invalid command。”

如果缺少 pkey，则需要安装更新的 openssl 并相应地设置 PATH。

我用 Homebrew 安装了一个更新的 OpenSSL 并像这样设置我的 PATH：

export PATH=/usr/local/Cellar/openssl/1.0.2m/bin/:$PATH

验证 pkey 是否可用：

openssl pkey -in

这应该显示 pkey 使用摘要：

Usage pkey [options]
where options are

现在脚本应该按预期工作。
