Question

我无法为字符串格式的公共密钥创建OpenSSL :: PKey :: RSA类的对象。以下是我的代码：

public_key = '-----BEGIN PUBLIC KEY-----MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAttI6ImgD74PhHWVqnrqSOmStboplyL02DB3/nc2iyDdYLzXoBIQN+NPMBPlsZlEKuKjsg5Ycfp6VjcmncM3CH9MGIr+Lmbj1HZmO/jJGJ84RPhzYOiZuElzs3seIcOtOa3BpFeqRsXJlrf1IVBKVU3erka5ACLVyrsjmp/VXMx5QjPD0qXARMGb6rDewTkyg3pGz07Y7rZgXkTl54ase+XaPegOankxdEQhVjPdrk7eSlIQS5Ni7FAcSyTOtYoPgiP7W0PolOMHvpFg96CHjc8V8xDsFdh0wbHd49WcKxiJMIfL65VUIW5aob9fw05a5FczyASa0iNtRiICy/QnCqQIDAQAB-----END PUBLIC KEY-----'
OpenSSL::PKey::RSA.new public_key

我遇到以下错误：

OpenSSL::PKey::RSAError: Neither PUB key nor PRIV key: nested asn1 error

我正在使用ruby版本的ruby 2.3.7。任何人都可以告诉我字符串或函数有什么问题吗？

我尝试添加\ n建议的解决方案here

public_key = "-----BEGIN PUBLIC KEY-----MIIB\nIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAttI6ImgD74PhHWVqnrqSOmStboplyL02DB3/nc2iyDdYLzXoBIQN+NPMBPlsZlEKuKjsg5Ycfp6VjcmncM3CH9MGIr+Lmbj1HZmO/jJGJ84RPhzYOiZuElzs3seIcOtOa3BpFeqRsXJlrf1IVBKVU3erka5ACLVyrsjmp/VXMx5QjPD0qXARMGb6rDewTkyg3pGz07Y7rZgXkTl54ase+XaPegOankxdEQhVjPdrk7eSlIQS5Ni7FAcSyTOtYoPgiP7W0PolOMHvpFg96CHjc8V8xDsFdh0wbHd49WcKxiJMIfL65VUIW5aob9fw05a5FczyASa0iNtRiICy/QnCqQIDA\nQAB-----END PUBLIC KEY-----"

但是我遇到同样的错误

OpenSSL::PKey::RSAError: Neither PUB key nor PRIV key: nested asn1 error

在不同位置添加\ n

public_key = "-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAttI6ImgD74PhHWVqnrqSOmStboplyL02DB3/nc2iyDdYLzXoBIQN+NPMBPlsZlEKuKjsg5Ycfp6VjcmncM3CH9MGIr+Lmbj1HZmO/jJGJ84RPhzYOiZuElzs3seIcOtOa3BpFeqRsXJlrf1IVBKVU3erka5ACLVyrsjmp/VXMx5QjPD0qXARMGb6rDewTkyg3pGz07Y7rZgXkTl54ase+XaPegOankxdEQhVjPdrk7eSlIQS5Ni7FAcSyTOtYoPgiP7W0PolOMHvpFg96CHjc8V8xDsFdh0wbHd49WcKxiJMIfL65VUIW5aob9fw05a5FczyASa0iNtRiICy/QnCqQIDAQAB\n-----END PUBLIC KEY-----"

正在生成相同的错误消息。

谢谢

Answer 1

OpenSSL :: PKey :: RSA.new类无法创建新对象，因为它们与公用字符串键有关。

我通过以下方式发现密钥无效：

在ruby控制台/ irb中

puts public_key.to_s.gsub('\n', "\n")

将输出保存到名为public_key.txt的文件中，并在ubuntu终端上运行以下命令

openssl pkey -inform PEM -pubin -in public_key.txt -noout &> /dev/null
if [ $? != 0 ] ; then
    echo "this was definitely not a public key in PEM format"
    exit 1
fi

如果密钥无效，则将打印上述脚本

这绝对不是PEM格式的公钥

如果密钥有效，将不打印任何内容。

谢谢

这不会为我产生任何错误（您的原始字符串产生了与您提到的错误相同的错误）。

require 'openssl'
public_key = "-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAttI6ImgD74PhHWVqnrqSOmStboplyL02DB3/nc2iyDdYLzXoBIQN+NPMBPlsZlEKuKjsg5Ycfp6VjcmncM3CH9MGIr+Lmbj1HZmO/jJGJ84RPhzYOiZuElzs3seIcOtOa3BpFeqRsXJlrf1IVBKVU3erka5ACLVyrsjmp/VXMx5QjPD0qXARMGb6rDewTkyg3pGz07Y7rZgXkTl54ase+XaPegOankxdEQhVjPdrk7eSlIQS5Ni7FAcSyTOtYoPgiP7W0PolOMHvpFg96CHjc8V8xDsFdh0wbHd49WcKxiJMIfL65VUIW5aob9fw05a5FczyASa0iNtRiICy/QnCqQIDAQAB\n-----END PUBLIC KEY-----"8xDsFdh0wbHd49WcKxiJMIfL65VUIW5aob9fw05a5FczyASa0iNtRiICy/QnCqQIDAQAB\n-----END PUBLIC KEY-----"
OpenSSL::PKey::RSA.new public_key

返回#<OpenSSL::PKey::RSA:0x00007fa78b9b6ee8>而不是错误。如果删除\n，则可以重现您指出的错误。

Ruby 2.5.3，macOS，使用通过自制软件安装的openssl。

无法在ruby中生成RSA公钥
