# 使用OpenSSL来产生RSA密钥

### OpenSSL安装

#### Linux（Ubuntu）

`sudo apt-get install openssl`

#### Windows

可以在官网下载 [Downloads](https://www.openssl.org/source/) .

#### macOS

自带，或者输入一下命令重新安装

`brew reinstall openssl`

### RSA密钥对的产生

#### Linux \ macOS

```
openssl genrsa -out pay_rsa_private_key.pem 1024
openssl pkcs8 -topk8 -inform PEM -in pay_rsa_private_key.pem  -outform PEM -nocrypt
openssl rsa -in pay_rsa_private_key.pem -pubout -out  pay_rsa_public_key.pem
```

#### Windows 在命令行窗口操作：

```
C:\OpenSSL-Win32\bin>openssl.exe
OpenSSL> genrsa -out pay_rsa_private_key.pem 1024
OpenSSL> pkcs8 -topk8 -inform PEM -in pay_rsa_private_key.pem  -outform PEM -nocrypt
OpenSSL> rsa -in pay_rsa_private_key.pem -pubout -out  pay_rsa_public_key.pem
OpenSSL> exit
```

#### 使用方式：

在当前目录下会产生两个文件pay\_rsa\_private\_key.pem和 pay\_rsa\_public\_key.pem. 前面一个是私钥文件，后面一个是公钥文件。商家自行保管私钥文件，用来对关键接口签名，并将公钥文件除注释部分内容通过接口上传，EchoooPay 后台会对接口验签。

**PKCS8格式的标注私钥文件**

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://doc-pay.echooo.xyz/echooopay/api-wen-dang/kai-fang-api-jian-quan-fang-shi/rsa-secret-create.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
