Acquiring PID and Keys
PID and MD5 key
1、Developers log on the Alipay Global Open Platform, and then click My Order on the upper right.
2、In the screen page, click See Partner ID(PID) or See Key to fetch the authorized account.
RSA key
Step 1 - RSA public and private key generation
You can use the OpenSSL command to generate.
First enter the OpenSSL tool, and then enter the following command.
| 1 | OpenSSL> genrsa -out rsa_private_key.pem 1024 # To generate a private key |
| 2 | OpenSSL> pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt -out rsa_private_key_pkcs8.pem #Java developers need to convert private key into PKCS8 format |
| 3 | OpenSSL> rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem # To generate a public key |
| 4 | OpenSSL> exit # Exit OpenSSL program |
After the above steps, in the current folder (OpenSSL run folder), developers can see rsa_private_key.pem (RSA private keys), rsa_private_key_pkcs8.pem (pkcs8 format of RSA private key) and rsa_public_key.pem (corresponding to the RSA public key), the 3 files. Developers will reserve the private key and submit the public key to the Alipay gateway for verifying the signature. The followings are examples of public key file and private key file.
Note:
For Java developers, remove the head, tail, line break and space of the private key output by pkcs8 in console, as a private key for developers. For .NET and PHP developers, they don’t need the pkcs8 command line operations.

Step 2 - Upload a public key & acquire Alipay public key
1. Please send your RSA public key to Global Merchant Technical Support (overseas_support@service.alibaba.com), together with your PID, for upload.
2. To obtain the Alipay public key for verify the validity of Async notification, please click Alipay Public Key.
For Alipay public key, we can see a string, as follows:
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCnxj/9qwVfgoUh/y2W89L6BkRAFljhNhgPdyPuBV64bfQNN1PjbCzkIM6qRdKBoLPXmKKMiFYnkd6rAoprih3/PrQEB/VsW8OoM8fxn67UDYuyBTqA23MML9q1+ilIZwBC2AQ2UBVOrFXfFl75p6/B5KsiNG9zpgmLCUYuLkxpLQIDAQAB
If you need a file mode (such as server-side SDK PHP / .NET version) to read Alipay public key, you need to mark the beginning and end and save as follows:
-----BEGIN PUBLIC KEY-----
