Golang APNs certificate file conversion (P12 to Pem)

This is a created article in which the information may have evolved or changed.

Golang does not support P12 parsing, so it needs to be converted to PEM

There are some, but not automatic conversions (non-interactive mode). The following conversions are non-interactive modes:

Generate temporary files Cert.pem, note passin and passout options

OpenSSL pkcs12-clcerts-nokeys-out cert.pem-in cert.p12-passin Pass:p12_pass

Generate Temporary Files Key.pem

OpenSSL pkcs12-nocerts-out key.pem-in cert.p12-passin pass:p12_pass-passout pass:tmp_pass

Remove the KEY.PEM password

OpenSSL rsa-in key.pem-out key.unencrypted.pem-passin Pass:tmp_pass

Generate Cert files that build Golang can process

Cert, Err: = TLS. Loadx509keypair (CERT.PEM, KEY.UNENCRYPTED.PEM)

This generates a certificate that Golang can handle.

Note:

P12_pass: password when generating the P12 file

Tmp_pass: The exported temporary password must be greater than or equal to 4 characters
