need to add this certificate to the keychain, of course you can double-click the Aps_development.cer file and you will find it associated with the private key.To create a PEM file to your current location, you have three files:CSR filePUSHCHATKEY.P12 private Key FileSSL Certificate (Aps_development.cer)Save these three files well. You can throw the CSR away, but I think it's easier to save it. When the certificate expires, you can use that CSR to

public key of the entity identified in the certificate (that is, your certificate contains your Public Key), because the certificate matches the public key with a specific individual, and the authenticity of the certificate is guaranteed by the Issuing Authority (that is to say, you can trust that your certificate is true). Therefore, the digital certificate provides a solution to the problem of finding the user's public key and knowing whether it is valid.OpenSSL contains the following extensi

Openssl uses the DSA algorithm to generate a signature instance. This article introduces how to use the DSA algorithm to generate a signature instance based on openssl. the method for generating a signature is simple. it is complicated to understand the intermediate principle. let's take a look. This article introduces how to use the DSA algorithm to generate a s

The public key and the private key are usually paired. When the public key is used, the corresponding private key exists. Generally, OpenSSL and the Public Key are easily obtained from the private key, therefore, to create a certificate, you must first create a private key. 1. Use OpenSSL to generate a private keyCommon generation algorithms include RSA and DSA. The private key generated by RSA can be used for encryption and signature, while the priva
