支付宝RSA签名验签工具签名格式化

Post Time:2019-06-18 12:23:44 Views:2.26 K

最近在做支付宝的支付接入,介于生产的统一支付服务器使用的事PHP5.3的版本。使用的支付宝支付sdk也是以前的比较老旧的,看了一遍蚂蚁金融的开发文档,尝试了很多次,都是因为应用公钥和秘钥格式的问题无法成功调起支付。

后来看了下前辈们的写法,都是把RSA的签名证书存成一个文件然后用sdk调用的,目前又不想重写前辈们的方法。毕竟涉及了太多的业务逻辑,所以也只能是照葫芦画瓜了。用支付宝官方的RSA生成的工具生成的公钥和秘钥都是适用新版支付宝服务端sdk用到旧版的sdk的话显然是不适用的。

支付宝工具生成的公钥

所以我需要把密钥和公钥格式化成pem证书的格式,就是有头有尾64个字符回车换一行,下面试代码;

<?php

密密麻麻,看不懂。周末快乐
