2017-01-24ssl: Correct ssl_certificate:validate/3Ingela Anderton Andin
Changes made to ssl_certificate:validate appear to be preventing CRL validation from happening when an id-ce-extKeyUsage extension is present in the cert before the DistributionPoint extension. https://github.com/erlang/otp/blob/448e8aca77dd29ed5b37d56f0700d24ac26a7243/lib/ssl/src/ssl_certificate.erl#L131 See also ERL-338 and PR-1302
2016-08-19Add option to bypass SSL PEM cacheFred Hebert
The current SSL implementation has a PEM cache running through the ssl manager process, whose primary role is caching CA chains from files on disk. This is intended as a way to save on disk operation when the requested certificates are often the same, and those cache values are both time-bound and reference-counted. The code path also includes caching the Erlang-formatted certificate as decoded by the public_key application The same code path is used for DER-encoded certificates, which are passed in memory and do not require file access. These certificates are cached, but not reference-counted and also not shared across connections. For heavy usage of DER-encoded certificates, the PEM cache becomes a central bottleneck for a server, forcing the decoding of every one of them individually through a single critical process. It is also not clear if the cache remains useful for disk certificates in all cases. This commit adds a configuration variable for the ssl application (bypass_pem_cache = true | false) which allows to open files and decode certificates in the calling connection process rather than the manager. When this action takes place, the operations to cache and return data are replaced to strictly return data. To provide a transparent behaviour, the 'CacheDbRef' used to keep track of the certificates in the cache is replaced by the certificates itself, and all further lookup functions or folds can be done locally. This has proven under benchmark to more than triple the performance of the SSL application under load (once the session cache had also been disabled).

2016-02-08ssl: verify cert signature against original cert binaryMatt Campbell
When searching for a certificate's issuer in the `CertDB`, verify the signature against the original DER certificate from the handshake instead of a re-encoding of the parsed certificate. This avoids false negatives due to differences between DER encoding implementations of OTP and other platforms.

2015-01-30ssl: Remove selfsigned anchor certificate from the certificate chainIngela Anderton Andin
A selfsigned trusted anchor should not be in the certifcate chain passed to the certificate path validation. Conflicts: lib/ssl/src/ssl_certificate.erl
2014-09-09ssl, public_key: Add new option partial_chainIngela Anderton Andin
Check that the certificate chain ends with a trusted ROOT CA e.i. a self-signed certificate, but provide an option partial_chain to enable the application to define an intermediat CA as trusted. TLS RFC says: "unknown_ca A valid certificate chain or partial chain was received, but the certificate was not accepted because the CA certificate could not be located or couldn't be matched with a known, trusted CA. This message is always fatal." and also states: "certificate_list This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it. Because certificate validation requires that root keys be distributed independently, the self-signed certificate that specifies the root certificate authority MAY be omitted from the chain, under the assumption that the remote end must already possess it in order to validate it in any case." X509 RFC says: "The selection of a trust anchor is a matter of policy: it could be the top CA in a hierarchical PKI, the CA that issued the verifier's own certificate(s), or any other CA in a network PKI. The path validation procedure is the same regardless of the choice of trust anchor. In addition, different applications may rely on different trust anchors, or may accept paths that begin with any of a set of trust anchors."
2014-08-11ssl: Make sure the correct ROOT-cert is usedIngela Anderton Andin
When dealing with older certificates that does not indicate its signer with a certificate extension, we must search the database for the issure. Finding the issuer is not enough, we need to verify the signature with the key in the found issuer cert.

2013-03-13public_key & ssl: Add support for ISO oids 1.3.14.3.2.29 and 1.3.14.3.2.27Ingela Anderton Andin
Some certificates may use these OIDs instead of the ones defined by PKIX/PKCS standard. Refactor code so that all handling of the "duplicate" oids is done by public_key. Update algorithm information in documentation.

2011-11-15Replaced ets:next traversal with ets:foldl and throwIngela Anderton Andin
ets:next needs an explicit safe_fixtable call to be safe, we rather use ets:foldl and throw to get out of it when we find the correct entry.
2011-06-29Removed global name from the certificate tabelIngela Anderton Andin
We want the certificate table to be handled the same way as the session table and not have a global name, so that we may easier create a separate ssl-manager to handle erlang distribution over ssl.
2010-11-30Fixed guard and test caseIngela Anderton Andin
Data to sign and verify should be inputed as binaries. Also cleaned up and moved some dialyzer specs.

maint-r14 * ia/ssl-and-public_key/verify_fun_peer_awarness/OTP-8873: Peer awarness
2010-09-29Peer awarnessIngela Anderton Andin
Changed the verify fun so that it differentiate between the peer certificate and CA certificates by using valid_peer or valid as the second argument to the verify fun. It may not always be trivial or even possible to know when the peer certificate is reached otherwise.

* ia/ssl-and-public_key/backwards-compatibility/OTP-8858: Backwards compatibility Conflicts: lib/ssl/src/ssl_certificate_db.erl Use short INFO-message. Debugging information can be fairly easily recreated so we do not want to clutter the logs.
2010-09-24Backwards compatibilityIngela Anderton Andin
Changed implementation to retain backwards compatibility for old option {verify, 0} that shall be equivalent to {verify, verify_none}, also separate the cases unknown CA and selfsigned peer cert, and restored return value of deprecated function public_key:pem_to_der/1.
2010-09-15Corrected and added dialyzer specsIngela Anderton Andin
2010-09-10Improved certificate extension handlingIngela Anderton Andin
Added the functionality so that the verification fun will be called when a certificate is considered valid by the path validation to allow access to eachs certificate in the path to the user application. Removed clause that only check that a extension is not critical, it does alter the verification rusult only withholds information from the application. Try to verify subject-AltName, if unable to verify it let application try.
2010-09-06Handling of path validation errors by the applicationIngela Anderton Andin
Changed the behavior of the verify_fun option so that the application can be responsible for handling path validation errors even on the server side. Also replaced the not yet documented validate_extensions_fun to be handled by the verify_fun instead. If the verify callback fun returns {fail, Reason}, the verification process is immediately stopped and an alert is sent to the peer and the TLS/SSL handshake is terminated. If the verify callback fun returns {valid, UserState}, the verification process is continued. If the verify callback fun always returns {valid, UserState}, the TLS/SSL handshake will not be terminated with respect to verification failures and the connection will be established. The verify callback fun will also be able to verify application specific extensions.
