This change means that there's n more need + to rebuild the .num files when some algorithms are excluded. + [Richard Levitte] + + *) Allow the verify time to be set by an application, + rather than always using the current time. + [Steve Henson] + + *) Phase 2 verify code reorganisation. The certificate + verify code now looks up an issuer certificate by a + number of criteria: subject name, authority key id + and key usage. It also verifies self signed certificates + by the same criteria. The main comparison function is + X509_check_issued() which performs these checks. + + Lot of changes were necessary in order to support this + without completely rewriting the lookup code. + + Authority and subject key identifier are now cached. + + The LHASH 'certs' is X509_STORE has now been replaced + by a STACK_OF(X509_OBJECT). This is mainly because an + LHASH can't store or retrieve multiple objects with + the same hash value. + + As a result various functions (which were all internal + use only) have changed to handle the new X509_STORE + structure. This will break anything that messed round + with X509_STORE internally. + + The functions X509_STORE_add_cert() now checks for an + exact match, rather than just subject name. + + The X509_STORE API doesn't directly support the retrieval + of multiple certificates matching a given criteria, however + this can be worked round by performing a lookup first + (which will fill the cache with candidate certificates) + and then examining the cache for matches. This is probably + the best we can do without throwing out X509_LOOKUP + entirely (maybe later...). + + The X509_VERIFY_CTX structure has been enhanced considerably. + + All certificate lookup operations now go via a get_issuer() + callback. Although this currently uses an X509_STORE it + can be replaced by custom lookups. This is a simple way + to bypass the X509_STORE hackery necessary to make this + work and makes it possible to use more efficient techniques + in future. A very simple version which uses a simple + STACK for its trusted certificate store is also provided + using X509_STORE_CTX_trusted_stack(). + + The verify_cb() and verify() callbacks now have equivalents + in the X509_STORE_CTX structure. + + X509_STORE_CTX also has a 'flags' field which can be used + to customise the verify behaviour. + [Steve Henson] + + *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which + excludes S/MIME capabilities. + [Steve Henson] + + *) When a certificate request is read in keep a copy of the + original encoding of the signed data and use it when outputing + again. Signatures then use the original encoding rather than + a decoded, encoded version which may cause problems if the + request is improperly encoded. + [Steve Henson] + + *) For consistency with other BIO_puts implementations, call + buffer_write(b, ...) directly in buffer_puts instead of calling + BIO_write(b, ...). + + In BIO_puts, increment b->num_write as in BIO_write. + [Peter.Sylvester@EdelWeb.fr] + + *) Fix BN_mul_word for the case where the word is 0. (We have to use + BN_zero, we may not return a BIGNUM with an array consisting of + words set to zero.) + [Bodo Moeller] + + *) Avoid calling abort() from within the library when problems are + detected, except if preprocessor symbols have been defined + (such as REF_CHECK, BN_DEBUG etc.). + [Bodo Moeller] + + *) New openssl application 'rsautl'. This utility can be + used for low level RSA operations. DER public key + BIO/fp routines also added. + [Steve Henson] + + *) New Configure entry and patches for compiling on QNX 4. + [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>] + + *) A demo state-machine implementation was sponsored by + Nuron (http://www.nuron.com/) and is now available in + demos/state_machine. + [Ben Laurie] + + *) New options added to the 'dgst' utility for signature + generation and verification. + [Steve Henson] + + *) Unrecognized PKCS#7 content types are now handled via a + catch all ASN1_TYPE structure. This allows unsupported + types to be stored as a "blob" and an application can + encode and decode it manually. + [Steve Henson] + + *) Fix various signed/unsigned issues to make a_strex.c + compile under VC++. + [Oscar Jacobsson <oscar.jacobsson@celocom.com>] + + *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct + length if passed a buffer. ASN1_INTEGER_to_BN failed + if passed a NULL BN and its argument was negative. + [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>] + + *) Modification to PKCS#7 encoding routines to output definite + length encoding. Since currently the whole structures are in + memory there's not real point in using indefinite length + constructed encoding. However if OpenSSL is compiled with + the flag PKCS7_INDEFINITE_ENCODING the old form is used. + [Steve Henson] + + *) Added BIO_vprintf() and BIO_vsnprintf(). + [Richard Levitte] + + *) Added more prefixes to parse for in the the strings written + through a logging bio, to cover all the levels that are available + through syslog. The prefixes are now: + + PANIC, EMERG, EMR => LOG_EMERG + ALERT, ALR => LOG_ALERT + CRIT, CRI => LOG_CRIT + ERROR, ERR => LOG_ERR + WARNING, WARN, WAR => LOG_WARNING + NOTICE, NOTE, NOT => LOG_NOTICE + INFO, INF => LOG_INFO + DEBUG, DBG => LOG_DEBUG + + and as before, if none of those prefixes are present at the + beginning of the string, LOG_ERR is chosen. + + On Win32, the LOG_* levels are mapped according to this: + + LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE + LOG_WARNING => EVENTLOG_WARNING_TYPE + LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE + + [Richard Levitte] + + *) Made it possible to reconfigure with just the configuration + argument "reconf" or "reconfigure". The command line arguments + are stored in Makefile.ssl in the variable CONFIGURE_ARGS, + and are retrieved from there when reconfiguring. + [Richard Levitte] + + *) MD4 implemented. + [Assar Westerlund <assar@sics.se>, Richard Levitte] + + *) Add the arguments -CAfile and -CApath to the pkcs12 utility. + [Richard Levitte] + + *) The obj_dat.pl script was messing up the sorting of object + names. The reason was that it compared the quoted version + of strings as a result "OCSP" > "OCSP Signing" because + " > SPACE. Changed script to store unquoted versions of + names and add quotes on output. It was also omitting some + names from the lookup table if they were given a default + value (that is if SN is missing it is given the same + value as LN and vice versa), these are now added on the + grounds that if an object has a name we should be able to + look it up. Finally added warning output when duplicate + short or long names are found. + [Steve Henson] + + *) Changes needed for Tandem NSK. + [Scott Uroff scott@xypro.com] + *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in RSA_padding_check_SSLv23(), special padding was never detected and thus the SSL 3.0/TLS 1.0 countermeasure against protocol |
