苹果p12证书转换[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

先生成本地的key

openssl genrsa -out aps_development.key 2048

# 将key转换导出csr证书
openssl req -new -sha256 -key aps_development.key -out aps_development.csr

拿着 aps_development.csr 在 苹果开发者网站 去得到 cer 然后解析cer

openssl x509 -inform DER -outform PEM -in aps_development.cer -out aps_development.pem

# 导出p12证书
openssl pkcs12 -inkey aps_development.key -in aps_development.pem -export -out aps_development.p12

p12 反向解析

# supersign 是密码
openssl pkcs12 -in ios_distribution.p12 -out newfile.crt.pem -clcerts -nokeys -password pass:supersign
openssl pkcs12 -in  ios_distribution.p12 -out newfile.key.pem -nocerts -nodes -password pass:supersign

nginx的需要key证书需要包含，-----BEGIN RSA PRIVATE KEY-----
他们提供的只有-----BEGIN PRIVATE KEY-----的证书，需要使用工具转换下：
openssl rsa -in 2_abc.com.key -out 2_abc.com_pri.key

给描述文件签名

        cmd = "openssl smime -sign -in %s -out %s -signer %s " \
              "-inkey %s -certfile %s -outform der -nodetach " % (
                  mobilconfig_path, sign_mobilconfig_path, ssl_pem_path, ssl_key_path, ssl_pem_path)
