Implementation of an X.509 certificate as specified in RFC 5280. Provides access to a certificate’s attributes and allows certificates to be read from a string, but also supports the creation of new certificates from scratch.
Certificate is capable of handling DER-encoded certificates and certificates encoded in OpenSSL’s PEM format.
raw = File.read "cert.cer" # DER- or PEM-encoded certificate = OpenSSL::X509::Certificate.new raw
A certificate may be encoded in DER format
cert = ... File.open("cert.cer", "wb") { |f| f.print cert.to_der }
or in PEM format
cert = ... File.open("cert.pem", "wb") { |f| f.print cert.to_pem }
X.509 certificates are associated with a private/public key pair, typically a RSA, DSA or ECC key (see also OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and OpenSSL::PKey::EC), the public key itself is stored within the certificate and can be accessed in form of an OpenSSL::PKey. Certificates are typically used to be able to associate some form of identity with a key pair, for example web servers serving pages over HTTPs use certificates to authenticate themselves to the user.
The public key infrastructure (PKI) model relies on trusted certificate authorities (“root CAs”) that issue these certificates, so that end users need to base their trust just on a selected few authorities that themselves again vouch for subordinate CAs issuing their certificates to end users.
The OpenSSL::X509 module provides the tools to set up an independent PKI, similar to scenarios where the ‘openssl’ command line tool is used for issuing certificates in a private PKI.
First, we need to create a “self-signed” root certificate. To do so, we need to generate a key first. Please note that the choice of “1” as a serial number is considered a security flaw for real certificates. Secure choices are integers in the two-digit byte range and ideally not sequential but secure random numbers, steps omitted here to keep the example concise.
root_key = OpenSSL::PKey::RSA.new 2048 # the CA's public/private key root_ca = OpenSSL::X509::Certificate.new root_ca.version = 2 # cf. RFC 5280 - to make it a "v3" certificate root_ca.serial = 1 root_ca.subject = OpenSSL::X509::Name.parse "/DC=org/DC=ruby-lang/CN=Ruby CA" root_ca.issuer = root_ca.subject # root CA's are "self-signed" root_ca.public_key = root_key.public_key root_ca.not_before = Time.now root_ca.not_after = root_ca.not_before + 2 * 365 * 24 * 60 * 60 # 2 years validity ef = OpenSSL::X509::ExtensionFactory.new ef.subject_certificate = root_ca ef.issuer_certificate = root_ca root_ca.add_extension(ef.create_extension("basicConstraints","CA:TRUE",true)) root_ca.add_extension(ef.create_extension("keyUsage","keyCertSign, cRLSign", true)) root_ca.add_extension(ef.create_extension("subjectKeyIdentifier","hash",false)) root_ca.add_extension(ef.create_extension("authorityKeyIdentifier","keyid:always",false)) root_ca.sign(root_key, OpenSSL::Digest.new('SHA256'))
The next step is to create the end-entity certificate using the root CA certificate.
key = OpenSSL::PKey::RSA.new 2048 cert = OpenSSL::X509::Certificate.new cert.version = 2 cert.serial = 2 cert.subject = OpenSSL::X509::Name.parse "/DC=org/DC=ruby-lang/CN=Ruby certificate" cert.issuer = root_ca.subject # root CA is the issuer cert.public_key = key.public_key cert.not_before = Time.now cert.not_after = cert.not_before + 1 * 365 * 24 * 60 * 60 # 1 years validity ef = OpenSSL::X509::ExtensionFactory.new ef.subject_certificate = cert ef.issuer_certificate = root_ca cert.add_extension(ef.create_extension("keyUsage","digitalSignature", true)) cert.add_extension(ef.create_extension("subjectKeyIdentifier","hash",false)) cert.sign(root_key, OpenSSL::Digest.new('SHA256'))
