Method: OpenSSL::SSL::SSLContext#add_certificate

Defined in:
ossl_ssl.c

#add_certificate(certificate, pkey[, extra_certs]) ⇒ self

Adds a certificate to the context. pkey must be a corresponding private key with certificate.

Multiple certificates with different public key type can be added by repeated calls of this method, and OpenSSL will choose the most appropriate certificate during the handshake.

#cert=, #key=, and #extra_chain_cert= are old accessor methods for setting certificate and internally call this method.

Parameters

certificate

A certificate. An instance of OpenSSL::X509::Certificate.

pkey

The private key for certificate. An instance of OpenSSL::PKey::PKey.

extra_certs

Optional. An array of OpenSSL::X509::Certificate. When sending a certificate chain, the certificates specified by this are sent following certificate, in the order in the array.

Example

rsa_cert = OpenSSL::X509::Certificate.new(...)
rsa_pkey = OpenSSL::PKey.read(...)
ca_intermediate_cert = OpenSSL::X509::Certificate.new(...)
ctx.add_certificate(rsa_cert, rsa_pkey, [ca_intermediate_cert])

ecdsa_cert = ...
ecdsa_pkey = ...
another_ca_cert = ...
ctx.add_certificate(ecdsa_cert, ecdsa_pkey, [another_ca_cert])

Returns:

  • (self)
