php读取der格式证书乱码解决方法
这篇文章主要介绍了php读取der格式证书乱码解决方法的相关资料,需要的朋友可以参考下
遇到的问题:
我的项目需要用到应用der格式的证书公钥及RSA算法来验签相关签名,PHP关于RSA算法不是很懂,手头上有Java和.net两种语言的实现,PHP实现甚感吃力。
小伙伴们的解答:
这个证书有他自己相应的编码,首先要找到这个,然后在用php读,设置对应的编码就好了。另外你如果是直接echo出证书内容的话,在那之前最好用 标签编码一下,否则他其实没乱码,只是你浏览器无法识别而已。还要注意你php那个文件的编码哦~~
直接读取当然是乱码了,der密钥证书本来就是二进制编码或者BASE64编码的文件,php可以用openssl_x509_parse函数来解析:
?

$cert = file_get_contents('filename.crt'); $ssl = openssl_x509_parse($cert); var_dump($ssl); ?> |

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
