OPENSSL-S_TIME(1ssl) OpenSSL OPENSSL-S_TIME(1ssl) NOM openssl-s_time - Programme d'analyse de performances SSL/TLS SYNOPSIS openssl s_time [-help] [-connect host:port] [-www page] [-cert filename] [-key filename] [-reuse] [-new] [-verify depth] [-time seconds] [-ssl3] [-tls1] [-tls1_1] [-tls1_2] [-tls1_3] [-bugs] [-cipher cipherlist] [-ciphersuites val] [-nameopt option] [-cafile file] [-CAfile file] [-no-CAfile] [-CApath dir] [-no-CApath] [-CAstore uri] [-no-CAstore] [-provider name] [-provider-path path] [-provparam [name:]key=value] [-propquery propq] DESCRIPTION This command implements a generic SSL/TLS client which connects to a remote host using SSL/TLS. It can request a page from the server and includes the time to transfer the payload data in its timing measurements. It measures the number of connections within a given timeframe, the amount of data transferred (if any), and calculates the average time spent for one connection. OPTIONS -help Afficher un message d'utilisation. -connect hote:port This specifies the host and optional port to connect to. If the host string is an IPv6 address, it must be enclosed in "[" and "]". -www page This specifies the page to GET from the server. A value of '/' gets the index.html page. If this parameter is not specified, then this command will only perform the handshake to establish SSL connections but not transfer any payload data. -cert certname Le certificat a utiliser, s'il est requis par le serveur. Par defaut, aucun certificat n'est utilise. Le fichier est au format PEM. -key keyfile La clef privee a utiliser. En absence d'indication, le fichier de certificats sera utilise. Le fichier est au format PEM. -verify profondeur La profondeur de verification a utiliser. Cela indique la taille maximale de la chaine de certificats du serveur et active la verification de certificat du serveur. Actuellement l'operation de verification continue apres les erreurs de facon a montrer tous les problemes lies a la chaine de certificats. Par consequent, la connexion n'echouera jamais a cause d'un echec de verification de certificat du serveur. -new Effectuer la mesure du temps en utilisant un nouvel identifiant de session pour chaque connexion. Si ni -new ni -reuse ne sont indiquees, elles sont toutes deux activees par defaut et executees a la suite. -reuse Effectuer la mesure du temps en utilisant le meme identifiant de session ; cela permet de tester le fonctionnement de la mise en cache des sessions. Si ni -new ni -reuse ne sont indiquees, elles sont toutes deux activees par defaut et executees a la suite. -bugs Plusieurs bogues sont connus dans les implementations SSL et TLS. L'ajout de cette option permet de contourner certains problemes. -cipher listechiffrements This allows the TLSv1.2 and below cipher list sent by the client to be modified. This list will be combined with any TLSv1.3 ciphersuites that have been configured. Although the server determines which cipher suite is used it should take the first supported cipher in the list sent by the client. See openssl-ciphers(1) for more information. -ciphersuites val This allows the TLSv1.3 ciphersuites sent by the client to be modified. This list will be combined with any TLSv1.2 and below ciphersuites that have been configured. Although the server determines which cipher suite is used it should take the first supported cipher in the list sent by the client. See openssl-ciphers(1) for more information. The format for this list is a simple colon (":") separated list of TLSv1.3 ciphersuite names. -time length Specifies how long (in seconds) this command should establish connections and optionally transfer payload data from a server. Server and client performance and the link speed determine how many connections it can establish. -nameopt option This specifies how the subject or issuer names are displayed. See openssl-namedisplay-options(1) for details. -CAfile file, -no-CAfile, -CApath dir, -no-CApath, -CAstore uri, -no-CAstore See "Trusted Certificate Options" in openssl-verification-options(1) for details. -provider nom -provider-path chemin -provparam [nom:]cle=valeur] -propquery propq Voir << Options de fournisseur >> dans openssl(1), provider(7) et property(7). -cafile fichier This is an obsolete synonym for -CAfile. -ssl3, -tls1, -tls1_1, -tls1_2, -tls1_3 See "TLS Version Options" in openssl(1). NOTES This command can be used to measure the performance of an SSL connection. To connect to an SSL HTTP server and get the default page the command openssl s_time -connect servername:443 -www / -CApath yourdir -CAfile yourfile.pem -cipher commoncipher [-ssl3] would typically be used (https uses port 443). commoncipher is a cipher to which both client and server can agree, see the openssl-ciphers(1) command for details. If the handshake fails then there are several possible causes, if it is nothing obvious like no client certificate then the -bugs and -ssl3 options can be tried in case it is a buggy server. In particular you should play with these options before submitting a bug report to an OpenSSL mailing list. A frequent problem when attempting to get client certificates working is that a web client complains it has no certificates or gives an empty list to choose from. This is normally because the server is not sending the clients certificate authority in its "acceptable CA list" when it requests a certificate. By using openssl-s_client(1) the CA list can be viewed and checked. However, some servers only request client authentication after a specific URL is requested. To obtain the list in this case it is necessary to use the -prexit option of openssl-s_client(1) and send an HTTP request for an appropriate page. Si un certificat est indique sur la ligne de commandes en utilisant l'option -cert, il ne sera pas utilise a moins que le serveur indique n'exige un certificat client. Par consequent, la simple utilisation d'un certificat client sur la ligne de commandes ne garantit pas que le certificat fonctionne. BOGUES Because this program does not have all the options of the openssl-s_client(1) program to turn protocols on and off, you may not be able to measure the performance of all protocols with all servers. L'option -verify devrait reellement quitter si la verification du serveur echoue. HISTORIQUE The -cafile option was deprecated in OpenSSL 3.0.
