* Move the now internal X.509-related structs into x509_lcl.h.tb2021-11-011-2/+3
| | | | | | | | Garbage collect the now unused LIBRESSL_CRYPTO_INTERNAL and LIBRESSL_OPAQUE_X509. Include "x509_lcl.h" where needed and fix a couple of unnecessary reacharounds. ok jsing

* Remove remaining error *_str_functs[]jsing2020-06-051-137/+5
| | | | | | | | | A number of years ago we dropped the concept of having function names in errors, since it is not that useful and very quickly gets out of sync when refactoring. It would seem that some new ones got imported and some missed the last clean up. ok tb@ beck@ "kill it with fire"
* Fix a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey.tb2019-10-043-4/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (Note that the CMS code is currently disabled.) Port of Edlinger's Fix for CVE-2019-1563 from OpenSSL 1.1.1 (old license) tests from bluhm@ ok jsing commit e21f8cf78a125cd3c8c0d1a1a6c8bb0b901f893f Author: Bernd Edlinger <bernd.edlinger@hotmail.de> Date: Sun Sep 1 00:16:28 2019 +0200 Fix a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey An attack is simple, if the first CMS_recipientInfo is valid but the second CMS_recipientInfo is chosen ciphertext. If the second recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct encryption key will be replaced by garbage, and the message cannot be decoded, but if the RSA decryption fails, the correct encryption key is used and the recipient will not notice the attack. As a work around for this potential attack the length of the decrypted key must be equal to the cipher default key length, in case the certifiate is not given and all recipientInfo are tried out. The old behaviour can be re-enabled in the CMS code by setting the CMS_DEBUG_DECRYPT flag.

* Work towards supporting Cryptographic Message Syntax (CMS) in libcrypto.jsing2019-08-1015-0/+6172
| | | | | | | | | | | | | | | | Cryptographic Message Syntax (CMS) is a standard for cryptographically protecting messages, as defined in RFC 5652. It is derived from PKCS #7 version 1.5 and utilises various ASN.1 structures, making it complex and fairly heavyweight. Various protocols - including RPKI (RFC 6480) - have been built on top of it, which means it is necessary to support CMS, in order to support RPKI. This imports around 6,000 lines of code from OpenSSL 1.1.1, which is still under the original OpenSSL license. Further work will occur in tree. Requested by and discussed with many. ok deraadt@ tb@

This is a verbatim import of Dmitry's work, and does not compile in this state; the forthcoming commits will address these issues. None of the GOST code is enabled in libcrypto yet, for it still gets compiled with OPENSSL_NO_GOST defined. However, the public header gost.h will be installed.
