|
* 应用公钥(SHA256withRsa)生成方法 |
|

|
|
|
* 1.1 在liunx 使用 openssl |
|

|
|
|
* 1.2 OpenSSL> genrsa -out rsa_private_key.pem 2048 #生成私钥 |
|
10
|
|
|
* 1.3 OpenSSL> pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt -out rsa_private_key_pkcs8.pem #Java开发者需要将私钥转换成PKCS8格式 |
|
11
|
|
|
* 1.4 OpenSSL> rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem #生成公钥 |
|
12
|
|
|
* 1.5 OpenSSL> exit #退出OpenSSL程序 |
|
13
|
|
|
* 1.6 复制rsa_public_key.pem 中间那一段到支付宝填写(注: 不要复制头和尾) |
|
14
|
|
|
* 2.1.PC登录需要签约: 第三方应用授权/获取会员信息 |
