Description
tls_load_file
() loads a certificate or key from disk into memory to be used with tls_config_set_ca_mem
(), tls_config_set_cert_mem
(), tls_config_set_crl_mem
() or tls_config_set_key_mem
(). A private key will be decrypted if the optional password argument is specified.
tls_unload_file
() unloads the memory that was returned from an earlier tls_load_file
() call, ensuring that the memory contents is discarded.
tls_default_ca_cert_file
() returns the path of the file that contains the default root certificates.
tls_config_set_ca_file
() loads a file containing the root certificates.
tls_config_set_ca_path
() sets the path (directory) which should be searched for root certificates.
tls_config_set_ca_mem
() sets the root certificates directly from memory.
tls_config_set_cert_file
() loads a file containing the public certificate.
tls_config_set_cert_mem
() sets the public certificate directly from memory.
tls_config_set_crl_file
() loads a file containing the Certificate Revocation List (CRL).
tls_config_set_crl_mem
() sets the CRL directly from memory.
tls_config_set_key_file
() loads a file containing the private key.
tls_config_set_key_mem
() directly sets the private key from memory.
tls_config_set_ocsp_staple_file
() loads a file containing a DER-encoded OCSP response to be stapled during the TLS handshake.
tls_config_set_ocsp_staple_mem
() sets a DER-encoded OCSP response to be stapled during the TLS handshake from memory.
tls_config_set_keypair_file
() loads two files from which the public certificate and private key will be read.
tls_config_set_keypair_mem
() directly sets the public certificate and private key from memory.
tls_config_set_keypair_ocsp_file
() loads three files containing the public certificate, private key, and DER-encoded OCSP staple.
tls_config_set_keypair_ocsp_mem
() directly sets the public certificate, private key, and DER-encoded OCSP staple from memory.
tls_config_add_keypair_file
() adds an additional public certificate and private key from the specified files, used as an alternative certificate for Server Name Indication (server only).
tls_config_add_keypair_mem
() adds an additional public certificate and private key from memory, used as an alternative certificate for Server Name Indication (server only).
tls_config_add_keypair_ocsp_file
() adds an additional public certificate, private key, and DER-encoded OCSP staple from the specified files, used as an alternative certificate for Server Name Indication (server only).
tls_config_add_keypair_ocsp_mem
() adds an additional public certificate, private key, and DER-encoded OCSP staple from memory, used as an alternative certificate for Server Name Indication (server only).
tls_config_clear_keys
() clears any secret keys from memory.
tls_config_set_verify_depth
() limits the number of intermediate certificates that will be followed during certificate validation.
tls_config_verify_client
() enables client certificate verification, requiring the client to send a certificate (server only).
tls_config_verify_client_optional
() enables client certificate verification, without requiring the client to send a certificate (server only).
Return Values
tls_load_file
() returns NULL
on error or an out of memory condition.
The other functions return 0 on success or -1 on error.
