Here 'version' is the + protocol version according to which the SSL library interprets + the current protocol message (SSL2_VERSION, SSL3_VERSION, or + TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or + the content type as defined in the SSL 3.0/TLS 1.0 protocol + specification (change_cipher_spec(20), alert(21), handshake(22)). + 'buf' and 'len' point to the actual message, 'ssl' to the + SSL object, and 'arg' is the application-defined value set by + SSL[_CTX]_set_msg_callback_arg(). + + 'openssl s_client' and 'openssl s_server' have new '-msg' options + to enable a callback that displays all protocol messages. + [Bodo Moeller] + + *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake + messages are stored in a single piece (fixed-length part and + variable-length part combined) and fix various bugs found on the way. + [Bodo Moeller] + + +) Change the shared library support so shared libraries are built as + soon as the corresponding static library is finished, and thereby get + openssl and the test programs linked against the shared library. + This still only happens when the keyword "shard" has been given to + the configuration scripts. + + NOTE: shared library support is still an experimental thing, and + backward binary compatibility is still not guaranteed. + ["Maciej W.

BIO_gethostbyname() does not know what timeouts are + appropriate, so entries would stay in cache even when they have + become invalid. + [Bodo Moeller; problem pointed out by Rich Salz + + +) New command line and configuration option 'utf8' for the req command. + This allows field values to be specified as UTF8 strings. + [Steve Henson] + + +) Add -multi and -mr options to "openssl speed" - giving multiple parallel + runs for the former and machine-readable output for the latter. + [Ben Laurie] + + +) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion + of the e-mail address in the DN (i.e., it will go into a certificate + extension only). The new configuration file option 'email_in_dn = no' + has the same effect. + [Massimiliano Pala madwolf@openca.org] + + *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when + faced with a pathologically small ClientHello fragment that does + not contain client_version: Instead of aborting with an error, + simply choose the highest available protocol version (i.e., + TLS 1.0 unless it is disabled). In practice, ClientHello + messages are never sent like this, but this change gives us + strictly correct behaviour at least for TLS. + [Bodo Moeller] + + +) Change all functions with names starting with des_ to be starting + with DES_ instead. This because there are increasing clashes with + libdes and other des libraries that are currently used by other + projects. The old libdes interface is provided, as well as crypt(), + if openssl/des_old.h is included. Note that crypt() is no longer + declared in openssl/des.h. + + NOTE: This is a major break of an old API into a new one. Software + authors are encouraged to switch to the DES_ style functions. Some + time in the future, des_old.h and the libdes compatibility functions + will be completely removed. + [Richard Levitte] + + *) Fix SSL handshake functions and SSL_clear() such that SSL_clear() + never resets s->method to s->ctx->method when called from within + one of the SSL handshake functions. + [Bodo Moeller; problem pointed out by Niko Baric] + + +) Test for certificates which contain unsupported critical extensions. + If such a certificate is found during a verify operation it is + rejected by default: this behaviour can be overridden by either + handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or + by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function + X509_supported_extension() has also been added which returns 1 if a + particular extension is supported. + [Steve Henson] + + *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert + (sent using the client's version number) if client_version is + smaller than the protocol version in use. Also change + ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if + the client demanded SSL 3.0 but only TLS 1.0 is enabled; then + the client will at least see that alert. + [Bodo Moeller] + + +) Modify the behaviour of EVP cipher functions in similar way to digests + to retain compatibility with existing code. + [Steve Henson] + + +) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain + compatibility with existing code. In particular the 'ctx' parameter does + not have to be to be initialized before the call to EVP_DigestInit() and + it is tidied up after a call to EVP_DigestFinal(). New function + EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function + EVP_MD_CTX_copy() changed to not require the destination to be + initialized valid and new function EVP_MD_CTX_copy_ex() added which + requires the destination to be valid. + + Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(), + EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex(). + [Steve Henson] + + +) Change ssl3_get_message (ssl/s3_both.c) and the functions using it + so that complete 'Handshake' protocol structures are kept in memory + instead of overwriting 'msg_type' and 'length' with 'body' data. + [Bodo Moeller] + + *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation + correctly. + [Bodo Moeller] + + +) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32. + [Massimo Santin via Richard Levitte] + + +) Major restructuring to the underlying ENGINE code. This includes + reduction of linker bloat, separation of pure "ENGINE" manipulation + (initialisation, etc) from functionality dealing with implementations + of specific crypto iterfaces. This change also introduces integrated + support for symmetric ciphers and digest implementations - so ENGINEs + can now accelerate these by providing EVP_CIPHER and EVP_MD + implementations of their own. This is detailed in crypto/engine/README + as it couldn't be adequately described here. However, there are a few + API changes worth noting - some RSA, DSA, DH, and RAND functions that + were changed in the original introduction of ENGINE code have now + reverted back - the hooking from this code to ENGINE is now a good + deal more passive and at run-time, operations deal directly with + RSA_METHODs, DSA_METHODs (etc) as they did before, rather than + dereferencing through an ENGINE pointer any more. Also, the ENGINE + functions dealing with BN_MOD_EXP[_CRT] handlers have been removed - + they were not being used by the framework as there is no concept of a + BIGNUM_METHOD and they could not be generalised to the new + 'ENGINE_TABLE' mechanism that underlies the new code. Similarly, + ENGINE_cpy() has been removed as it cannot be consistently defined in + the new code. + [Geoff Thorpe] + + +) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds. + [Steve Henson] + + +) Change mkdef.pl to sort symbols that get the same entry number, + and make sure the automatically generated functions ERR_load_* + become part of libeay.num as well. + [Richard Levitte] + + *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a + client receives HelloRequest while in a handshake. + [Bodo Moeller; bug noticed by Andy Schneider ] + + +) New function SSL_renegotiate_pending(). This returns true once + renegotiation has been requested (either SSL_renegotiate() call + or HelloRequest/ClientHello receveived from the peer) and becomes + false once a handshake has been completed. + (For servers, SSL_renegotiate() followed by SSL_do_handshake() + sends a HelloRequest, but does not ensure that a handshake takes + place. SSL_renegotiate_pending() is useful for checking if the + client has followed the request.) + [Bodo Moeller] + + +) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION. + By default, clients may request session resumption even during + renegotiation (if session ID contexts permit); with this option, + session resumption is possible only in the first handshake. + [Bodo Moeller] + + *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C + should end in 'break', not 'goto end' which circuments various + cleanups done in state SSL_ST_OK. But session related stuff + must be disabled for SSL_ST_OK in the case that we just sent a + HelloRequest. + + Also avoid some overhead by not calling ssl_init_wbio_buffer() + before just sending a HelloRequest. + [Bodo Moeller, Eric Rescorla ] + + *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't + reveal whether illegal block cipher padding was found or a MAC + verification error occured. (Neither SSLerr() codes nor alerts + are directly visible to potential attackers, but the information + may leak via logfiles.) + + Similar changes are not required for the SSL 2.0 implementation + because the number of padding bytes is sent in clear for SSL 2.0, + and the extra bytes are just ignored. However ssl/s2_pkt.c + failed to verify that the purported number of padding bytes is in + the legal range. + [Bodo Moeller] + + +) Add some demos for certificate and certificate request creation. + [Steve Henson] + + +) Make maximum certificate chain size accepted from the peer application + settable (SSL*_get/set_max_cert_list()), as proposed by + "Douglas E.
