Configuration - parameters found in this example file are expected to be used in main - apt.conf file, just like other configuration parameters for different - methods (ftp, file, ...). - - This example file starts with a common setup that voluntarily exhibits - all available configurations knobs with simple comments. Extended - comments on the behavior of the option is provided at the end for - better readability. As a matter of fact, a common configuration file - will certainly contain far less elements and benefit of default values - for many parameters. - - Because some configuration parameters for apt https method in following - examples apply to specific (fictional) repositories, the associated - sources.list file is provided here: - - ... - - deb https://secure.dom1.tld/debian unstable main contrib non-free - deb-src https://secure.dom1.tld/debian unstable main contrib non-free - - deb https://secure.dom2.tld/debian unstable main contrib non-free - deb-src https://secure.dom2.tld/debian unstable main contrib non-free - - ... - - - Some notes on the servers: - - - secure.dom1.tld is freely accessible using https (no client - authentication is required). - - secure.dom1.tld certificate is part of a multi level PKI, and we - want to specifically check the issuer of its certificate. We do - not have the constraint for secure.dom2.tld - - secure.dom2.tld requires client authentication by certificate - to access its content. - - The certificate presented by both server have (as expected) a CN that - matches their respective DNS names. - - We have CRL available for both dom1.tld and dom2.tld PKI, and intend - to use them. - - It sometimes happens that we had other more generic https available - repository to our list. We want the checks to be performed against - a common list of anchors (like the one provided by ca-certificates - package for instance) - - The sample configuration below basically covers those simple needs. -*/ - - -// Verify peer certificate and also matching between certificate name -// and server name as provided in sources.list (default values) -Acquire::https::Verify-Peer "true"; -Acquire::https::Verify-Host "true"; - -// Except otherwise specified, use that list of anchors -Acquire::https::CaInfo "/etc/ssl/certs/ca-certificates.pem"; - -// Use a specific anchor and associated CRL. Enforce issuer of -// server certificate using its cert. -Acquire::https::secure.dom1.tld::CaInfo "/etc/apt/certs/ca-dom1-crt.pem"; -Acquire::https::secure.dom1.tld::CrlFile "/etc/apt/certs/ca-dom1-crl.pem"; -Acquire::https::secure.dom1.tld::IssuerCert "/etc/apt/certs/secure.dom1-issuer-crt.pem"; - -// Like previous for anchor and CRL, but also provide our -// certificate and keys for client authentication. -Acquire::https::secure.dom2.tld::CaInfo "/etc/apt/certs/ca-dom2-crt.pem"; -Acquire::https::secure.dom2.tld::CrlFile "/etc/apt/certs/ca-dom2-crl.pem"; -Acquire::https::secure.dom2.tld::SslCert "/etc/apt/certs/my-crt.pem"; -Acquire::https::secure.dom2.tld::SslKey "/etc/apt/certs/my-key.pem"; - -// No need to downgrade, TLS will be proposed by default. Uncomment -// to have SSLv3 proposed. -// Acquire::https::mirror.ipv6.ssi.corp::SslForceVersion "SSLv3"; - -// No need for more debug if every is fine (default). Uncomment -// me to get additional information. -// Debug::Acquire::https "true"; - - -/* - Options with extended comments: - - Acquire::https[::repo.domain.tld]::CaInfo "/path/to/ca/certs.pem"; - - A string providing the path of a file containing the list of trusted - CA certificates used to verify the server certificate. The pointed - file is made of the concatenation of the CA certificates (in - PEM format) creating the chain used for the verification of the path - from the root (self signed one). If the remote server provides the - whole chain during the exchange, the file need only contain the root - certificate. Otherwise, the whole chain is required. - - If you need to support multiple authorities, the only way is to - concatenate everything. - - If None is provided, the default CA bundle used by GnuTLS (apt https - method is linked against libcurl-gnutls) is used. At the time of - writing, /etc/ssl/certs/ca-certificates.crt. - - If no specific hostname is provided, the file is used by default - for all https targets. If a specific mirror is provided, it is - used for the https entries in the sources.list file that use that - repository (with the same name). - - Acquire::https[::repo.domain.tld]::CrlFile "/path/to/all/crl.pem"; - - Like previous knob but for passing the list of CRL files (in PEM - format) to be used to verify revocation status. Again, if the - option is defined with no specific mirror (probably makes little - sense), this CRL information is used for all defined https entries - in sources.list file. In a mirror specific context, it only applies - to that mirror. - - Acquire::https[::repo.domain.tld]::IssuerCert "/path/to/issuer/cert.pem"; - - Allows one to constrain the issuer of the server certificate (for all - https mirrors or a specific one) to a specific issuer. If the - server certificate has not been issued by this certificate, - connection fails. - - Acquire::https[::repo.domain.tld]::Verify-Peer "true"; - - When authenticating the server, if the certificate verification fails - for some reason (expired, revoked, man in the middle, lack of anchor, - ...), the connection fails. This is obviously what you want in all - cases and what the default value (true) of this option provides. - - If you know EXACTLY what you are doing, setting this option to "false" - allow you to skip peer certificate verification and make the exchange - succeed. Again, this option is for debugging or testing purpose only. - It removes ALL the security provided by the use of SSL.TLS to secure - the HTTP exchanges. - - Acquire::https[::repo.domain.tld]::Verify-Host "true"; - - The certificate provided by the server during the TLS/SSL exchange - provides the identity of the server which should match the DNS name - used to access it. By default, as requested by RFC 2818, the name - of the mirror is checked against the identity found in the - certificate. This default behavior is safe and should not be - changed. If you know that the server you are using has a DNS name - which does not match the identity in its certificate, you can - [report that issue to its administrator or] set the option to - "false", which will prevent the comparison to be done. - - The options can be set globally or on a per-mirror basis. If set - globally, the DNS name used is the one found in the sources.list - file in the https URI. - - Acquire::https[::repo.domain.tld]::SslCert "/path/to/client/cert.pem"; - Acquire::https[::repo.domain.tld]::SslKey "/path/to/client/key.pem"; - - These two options provides support for client authentication using - certificates. They respectively accept the X.509 client certificate - in PEM format and the associated client key in PEM format (non - encrypted form). - - The options can be set globally (which rarely makes sense) or on a - per-mirror basis. - - Acquire::https[::repo.domain.tld]::SslForceVersion "TLSv1"; - - This option can be use to select the version which will be proposed - to the server. "SSLv3" and "TLSv1" are supported. SSLv2, which is - considered insecure anyway is not supported (by gnutls, which is - used by libcurl against which apt https method is linked). - - When the option is set to "SSLv3" to have apt propose SSLv3 (and - associated sets of ciphersuites) instead of TLSv1 (the default) - when performing the exchange. This prevents the server to select - TLSv1 and use associated ciphersuites. You should probably not use - this option except if you know exactly what you are doing. - - Note that the default setting does not guarantee that the server - will not select SSLv3 (for ciphersuites and SSL/TLS version as - selection is always done by the server, in the end). It only means - that apt will not advertise TLS support. - - Debug::Acquire::https "true"; - - This option can be used to show debug information. Because it is - quite verbose, it is mainly useful to debug problems in case of - failure to connect to a server for some reason. The default value - is "false". - -*/ |
