苹果推送证书转为pem文件

关于配置推送证书给后台
cer证书生成pem文件:
openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem

p12生成pem文件:
openssl pkcs12 -nocerts -out PushChatKey.pem -in Push.p12
提示:
Enter Import Password:
MAC verified OK
Enter PEM pass phrase: 需要输入密码
Verifying - Enter PEM pass phrase: 需要确认密码
将生成的两个pem文件给后台,后台会设置配置密码,就可以用了

把PushChatCert.pem和PushChatKey.pem合并为一个pem文件
cat dahoufangChatCert.pem dahoufangChatKey.pem >dahoufang.pem

测试苹果推送服务器是否可以连通:
telnet gateway.sandbox.push.apple.com 2195

测试生成的key.pem 和 cert.pem是否正常:
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert siJiBanChatCert.pem -key siJiBanChatKey.pem
