| | | | | | The algorithm is insecure and yet its description would spread over three paragraphs in the cipher list, including remarkable advice like using a 40 bit key length.

| | | | | | | | | | | | both resulting pages are still long. Mention a number of missing functions. Add some text from the OpenSSL 1.1.1 EVP_aes.pod manual page, which is still under a free license. Add missing HISTORY information. Triggered by tb@ providing EVP_aes_{128,192,256}_wrap(3) in evp.h rev. 1.74.

| | | | No binary change.
* In evp.h rev. 1.75, tb@ provided EVP_PKEY_get0_hmac(3).schwarze2019-03-181-3/+29
| | | | | | | | | Document it. Even though OpenSSL muddles the waters by lumping the description together with the other EVP_PKEY_get0_*() functions, describe it separately because a char * has no reference count and because the function fills in an additional length parameter.

| | | | | | | | | | | | | implementation based on the one in OpenSSL 1.0.2r which is still freely licensed. The functions are undocumented in OpenSSL. To use them, one needs to set the undocumented EVP_CIPHER_CTX_FLAG_WRAP_ALLOW flag on the EVP_CIPHER_CTX. resolves #505 ok jsing

* Correct return value handling in tls13_handshake_recv_action().jsing2019-03-171-2/+4
| | | | | | | | The recv action handler returns success/failure, rather than a TLS13_IO_* value, which is what tls13_handshake_recv_action() needs to return. Failure previously mapped to TLS13_IO_EOF, which is not ideal. ok tb@
* Partially clean up the TLS1_get_{,client}_version macros.jsing2019-03-174-15/+14
| | | | | | | | | LibreSSL only supports TLSv1.0 and above, hence the checks the macros are performing are useless. Simplify them to their effective code. Also place both under #ifndef LIBRESSL_INTERNAL and use the variables directly in our code, which improves readability. ok tb@
* Remove the alert level from the TLSv1.3 alert callback.jsing2019-03-173-7/+6
| | | | | | | | In TLSv1.3 the alert level is effectively meaningless and the record layer has already checked that it is appropriate. As such, drop it from the alert callback. ok tb@
* Document the return values of X509_delete_ext(3) and X509_add_ext(3).schwarze2019-03-151-11/+15
| | | | | | From Viktor Dukhovni via OpenSSL commit 0df65d82 Jun 12 11:51:53 2018 -0400 which is still under a free license because it is before the 1.1.1 branch point. While here, add several missing const qualifiers.

* Fix a number of ASN1_INTEGER vs ASN1_STRING mixups coming from thetb2019-03-135-13/+11
| | | | | | | | | | | mechanical M_ASN1 macro expansion. The ASN1_INTEGER_cmp function takes signs into account while ASN1_STRING_cmp doesn't. The mixups mostly involve serialNumbers, which, in principle, should be positive. However, it is unclear whether that is checked or enforced anywhere in the code, so these are probably bugs.

* rename CRYPTO_set_locking_callback.3 to CRYPTO_lock.3schwarze2019-03-102-4/+4

* delete functions from the manual page that do nothing in LibreSSLschwarze2019-03-103-318/+87
| | | | | | | and that don't do anything in OpenSSL either; no significant amount of text remains from OpenSSL, so change the Copyright information and license of CRYPTO_set_locking_callback.3; OK inoguchi@ jmc@

* Implement non-SSL_MODE_ENABLE_PARTIAL_WRITE in tls13_legacy_write_bytes().jsing2019-02-281-3/+34
| | | | | | | In non-SSL_MODE_ENABLE_PARTIAL_WRITE mode we have to write out all the things and only return success once all of the data has been sent. ok inoguchi@ tb@
* Automatically complete the handshake from tls13_legacy_{read,write}_bytes()jsing2019-02-283-3/+17
| | | | | | | | | | | | | | If the TLS handshake has not been completed, automatically complete the handshake as part of the read/write call, implementing the current SSL_read()/SSL_write() behaviour. Once the TLS handshake is completed we push a WANT_POLLIN or WANT_POLLOUT back up to the caller, since some applications appear to incorrectly call SSL_read() or SSL_write(), rather than repeating the previous call. This can lead to attempts to read data that does not exist, since the WANT_POLLIN was actually triggered as part of the handshake. ok inoguchi@ tb@
* Set the SSL state as part of tls13_legacy_connect().jsing2019-02-281-2/+5
| | | | | | | | Set the SSL state to SSL_ST_CONNECT during the TLSv1.3 handshake and to SSL_ST_OK once the handshake completes, since some applications currently rely on this information to function correctly. ok inoguchi@ tb@
