How to convert a PFX ssl certificate to PEM? If you are in Brazil and buy an A1 (e-CNPJ) certificate from CertSign it comes as a PFX. We need to convert it to PEM format so we can use the certificate to sign documents electronically and use it to access a lot of APIs, incluing NFe.
### pfx to pem, complete edition:
$ openssl pkcs12 -in filename.pfx -nocerts -out key.pem
$ openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem
$ openssl pkcs12 -in filename.pfx -cacerts -out ca_cert.pem
require 'rubygems'
require 'mechanize'
FIRST_NAME = 'FIRST_NAME'
LAST_NAME = 'LAST_NAME'
PHONE = 'PHONE'
EMAIL = 'EMAIL@provider.com'
PARTY_SIZE = 2
SCHEDULE_RANGE = { :start_time => '19:00', :end_time => '20:30' }
