DESCRIPTION
These functions load the certificates and private keys into theThe SSL_CTX_* class of functions loads the certificates and keys into the
The SSL_* class of functions only loads certificates and keys into a specific
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
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_CTX_use_certificate_chain_file() loads a certificate chain from file into ctx. The certificates must be in
SSL_CTX_use_PrivateKey() adds pkey as private key to ctx. SSL_CTX_use_RSAPrivateKey() adds the private key rsa of type
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
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_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 (
NOTES
The internal certificate store of OpenSSL can hold several private key/certificate pairs at a time. The certificate used depends on the cipher selected, see also SSL_CTX_set_cipher_list(3).When reading certificates and private keys from file, files of type
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_add1_chain_cert(3). Note: versions of OpenSSL before 1.0.2 only had a single certificate chain store for all certificate types, OpenSSL 1.0.2 and later have a separate chain store for each type. SSL_CTX_use_certificate_chain_file() should be used instead of the SSL_CTX_use_certificate_file() function in order to allow the use of complete certificate chains even when no trusted
If additional certificates are needed to complete the chain during the
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.)
