       These functions load the certificates and private keys into the SSL_CTX or SSL object,

       The SSL_CTX_* class of functions loads the certificates and keys into the SSL_CTX object
       ctx. The information is passed to SSL objects ssl created from ctx with SSL_new(3) by
       copying, so that changes applied to ctx do not propagate to already existing SSL objects.

       The SSL_* class of functions only loads certificates and keys into a specific SSL object.
       The specific information is kept, when SSL_clear(3) is called for this SSL object.

       SSL_CTX_use_certificate() loads the certificate x into ctx, SSL_use_certificate() loads x
       into ssl. The rest of the certificates needed to form the complete certificate chain can
       be specified using the SSL_CTX_add_extra_chain_cert(3) function.

       SSL_CTX_use_certificate_ASN1() loads the ASN1 encoded certificate from the memory location
       d (with length len) into ctx, SSL_use_certificate_ASN1() loads the ASN1 encoded
       certificate into ssl.

       SSL_CTX_use_certificate_file() loads the first certificate stored in file into ctx. The
       formatting type of the certificate must be specified from the known types
       SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.  SSL_use_certificate_file() loads the certificate
       from file into ssl.  See the NOTES section on why SSL_CTX_use_certificate_chain_file()
       should be preferred.

       SSL_CTX_use_certificate_chain_file() loads a certificate chain from file into ctx. The
       certificates must be in PEM format and must be sorted starting with the subject's
       certificate (actual client or server certificate), followed by intermediate CA
       certificates if applicable, and ending at the highest level (root) CA.  There is no
       corresponding function working on a single SSL object.

       SSL_CTX_use_PrivateKey() adds pkey as private key to ctx.  SSL_CTX_use_RSAPrivateKey()
       adds the private key rsa of type RSA to ctx. SSL_use_PrivateKey() adds pkey as private key
       to ssl; SSL_use_RSAPrivateKey() adds rsa as private key of type RSA to ssl.  If a
       certificate has already been set and the private does not belong to the certificate an
       error is returned. To change a certificate, private key pair the new certificate needs to
       be set with SSL_use_certificate() or SSL_CTX_use_certificate() before setting the private
       key with SSL_CTX_use_PrivateKey() or SSL_use_PrivateKey().

       SSL_CTX_use_PrivateKey_ASN1() adds the private key of type pk stored at memory location d
       (length len) to ctx.  SSL_CTX_use_RSAPrivateKey_ASN1() adds the private key of type RSA
       stored at memory location d (length len) to ctx.  SSL_use_PrivateKey_ASN1() and
       SSL_use_RSAPrivateKey_ASN1() add the private key to ssl.

       SSL_CTX_use_PrivateKey_file() adds the first private key found in file to ctx. The
       formatting type of the certificate must be specified from the known types
       SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.  SSL_CTX_use_RSAPrivateKey_file() adds the first
       private RSA key found in file to ctx. SSL_use_PrivateKey_file() adds the first private key
       found in file to ssl; SSL_use_RSAPrivateKey_file() adds the first private RSA key found to

       SSL_CTX_check_private_key() checks the consistency of a private key with the corresponding
       certificate loaded into ctx. If more than one key/certificate pair (RSA/DSA) is installed,
       the last item installed will be checked. If e.g. the last item was a RSA certificate or
       key, the RSA key/certificate pair will be checked. SSL_check_private_key() performs the
       same check for ssl. If no key/certificate was explicitly added for this ssl, the last item
       added into ctx will be checked.

       The internal certificate store of OpenSSL can hold two private key/certificate pairs at a
       time: one key/certificate of type RSA and one key/certificate of type DSA. The certificate
       used depends on the cipher select, see also SSL_CTX_set_cipher_list(3).

       When reading certificates and private keys from file, files of type SSL_FILETYPE_ASN1
       (also known as DER, binary encoding) can only contain one certificate or private key,
       consequently SSL_CTX_use_certificate_chain_file() is only applicable to PEM formatting.
       Files of type SSL_FILETYPE_PEM can contain more than one item.

       SSL_CTX_use_certificate_chain_file() adds the first certificate found in the file to the
       certificate store. The other certificates are added to the store of chain certificates
       using SSL_CTX_add_extra_chain_cert(3).  There exists only one extra chain store, so that
       the same chain is appended to both types of certificates, RSA and DSA! If it is not
       intended to use both type of certificate at the same time, it is recommended to use the
       SSL_CTX_use_certificate_chain_file() instead of the SSL_CTX_use_certificate_file()
       function in order to allow the use of complete certificate chains even when no trusted CA
       storage is used or when the CA issuing the certificate shall not be added to the trusted
       CA storage.

       If additional certificates are needed to complete the chain during the TLS negotiation, CA
       certificates are additionally looked up in the locations of trusted CA certificates, see

       The private keys loaded from file can be encrypted. In order to successfully load
       encrypted keys, a function returning the passphrase must have been supplied, see
       SSL_CTX_set_default_passwd_cb(3).  (Certificate files might be encrypted as well from the
       technical point of view, it however does not make sense as the data in the certificate is
       considered public anyway.)

       On success, the functions return 1.  Otherwise check out the error stack to find out the

       ssl(3), SSL_new(3), SSL_clear(3), SSL_CTX_load_verify_locations(3),
       SSL_CTX_set_default_passwd_cb(3), SSL_CTX_set_cipher_list(3),
       SSL_CTX_set_client_cert_cb(3), SSL_CTX_add_extra_chain_cert(3)

       Support for DER encoded private keys (SSL_FILETYPE_ASN1) in SSL_CTX_use_PrivateKey_file()
       and SSL_use_PrivateKey_file() was added in 0.9.8 .
