Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ *) Initial code to implement OCSP basic response verify. This
+ is currently incomplete. Currently just finds the signer's
+ certificate and verifies the signature on the response.
+ [Steve Henson]
+
+ *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
+ value of OPENSSLDIR. This is available via the new '-d' option
+ to 'openssl version', and is also included in 'openssl version -a'.
+ [Bodo Moeller]
+
+ *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
+ call failed, free the DSA structure.
+ [Bodo Moeller]
+
+ *) Allowing defining memory allocation callbacks that will be given
+ file name and line number information in additional arguments
+ (a const char* and an int). The basic functionality remains, as
+ well as the original possibility to just replace malloc(),
+ realloc() and free() by functions that do not know about these
+ additional arguments. To register and find out the current
+ settings for extended allocation functions, the following
+ functions are provided:
+
+ CRYPTO_set_mem_ex_functions
+ CRYPTO_set_locked_mem_ex_functions
+ CRYPTO_get_mem_ex_functions
+ CRYPTO_get_locked_mem_ex_functions
+
+ These work the same way as CRYPTO_set_mem_functions and friends.
+ CRYPTO_get_[locked_]mem_functions now writes 0 where such an
+ extended allocation function is enabled.
+ Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
+ a conventional allocation function is enabled.
+ [Richard Levitte, Bodo Moeller]
+
+ *) Fix to uni2asc() to cope with zero length Unicode strings.
+ These are present in some PKCS#12 files.
+ [Steve Henson]
+
+ *) Finish off removing the remaining LHASH function pointer casts.
+ There should no longer be any prototype-casting required when using
+ the LHASH abstraction, and any casts that remain are "bugs". See
+ the callback types and macros at the head of lhash.h for details
+ (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
+ [Geoff Thorpe]
+
+ *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
+ If an EGD or PRNGD is running and enough entropy is returned, automatic
+ seeding like with /dev/[u]random will be performed.
+ Positions tried are: /etc/entropy, /var/run/egd-pool.
+ [Lutz Jaenicke]
+
+ *) Change the Unix RAND_poll() variant to be able to poll several
+ random devices and only read data for a small fragment of time
+ to avoid hangs. Also separate out the Unix variant to it's own
+ file, rand_unix.c. For VMS, there's a currently-empty rand_vms.c.
+ [Richard Levitte]
+
+ *) Move OCSP client related routines to ocsp_cl.c. These
+ provide utility functions which an application needing
+ to issue a request to an OCSP responder and analyse the
+ response will typically need: as opposed to those which an
+ OCSP responder itself would need which will be added later.
+
+ OCSP_request_sign() signs an OCSP request with an API similar
+ to PKCS7_sign(). OCSP_response_status() returns status of OCSP
+ response. OCSP_response_get1_basic() extracts basic response
+ from response. OCSP_resp_find_status(): finds and extracts status
+ information from an OCSP_CERTID structure (which will be created
+ when the request structure is built). These are built from lower
+ level functions which work on OCSP_SINGLERESP structures but
+ wont normally be used unless the application wishes to examine
+ extensions in the OCSP response for example.
+
+ Replace nonce routines with a pair of functions.
+ OCSP_request_add1_nonce() adds a nonce value and optionally
+ generates a random value. OCSP_check_nonce() checks the
+ validity of the nonce in an OCSP response.
+ [Steve Henson]
+
+ *) Change function OCSP_request_add() to OCSP_request_add0_id().
+ This doesn't copy the supplied OCSP_CERTID and avoids the
+ need to free up the newly created id. Change return type
+ to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
+ This can then be used to add extensions to the request.
+ Deleted OCSP_request_new(), since most of its functionality
+ is now in OCSP_REQUEST_new() (and the case insensitive name
+ clash) apart from the ability to set the request name which
+ will be added elsewhere.
+ [Steve Henson]
+
+ *) Update OCSP API. Remove obsolete extensions argument from
+ various functions. Extensions are now handled using the new
+ OCSP extension code. New simple OCSP HTTP function which
+ can be used to send requests and parse the response.
+ [Steve Henson]
+
+ *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
+ ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
+ uses the special reorder version of SET OF to sort the attributes
+ and reorder them to match the encoded order. This resolves a long
+ standing problem: a verify on a PKCS7 structure just after signing
+ it used to fail because the attribute order did not match the
+ encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
+ it uses the received order. This is necessary to tolerate some broken
+ software that does not order SET OF. This is handled by encoding
+ as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
+ to produce the required SET OF.
+ [Steve Henson]
+
+ *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
+ OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
+ files to get correct declarations of the ASN.1 item variables.
+ [Richard Levitte]
+
+ *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
+ PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
+ asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
+ NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
+ New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
+ ASN1_ITEM and no wrapper functions.
+ [Steve Henson]
+
+ *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
+ replace the old function pointer based I/O routines. Change most of
+ the *_d2i_bio() and *_d2i_fp() functions to use these.
+ [Steve Henson]
+
+ *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
+ lines, recognice more "algorithms" that can be deselected, and make
+ it complain about algorithm deselection that isn't recognised.
+ [Richard Levitte]
+
+ *) New ASN1 functions to handle dup, sign, verify, digest, pack and
+ unpack operations in terms of ASN1_ITEM. Modify existing wrappers
+ to use new functions. Add NO_ASN1_OLD which can be set to remove
+ some old style ASN1 functions: this can be used to determine if old
+ code will still work when these eventually go away.
+ [Steve Henson]
+
+ *) New extension functions for OCSP structures, these follow the
+ same conventions as certificates and CRLs.
+ [Steve Henson]
+
*) New function X509V3_add1_i2d(). This automatically encodes and
adds an extension. Its behaviour can be customised with various
flags to append, replace or delete. Various wrappers added for
*) Fix ssl3_pending: If the record in s->s3->rrec is not of type
SSL3_RT_APPLICATION_DATA, return 0.
+ Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
[Bodo Moeller]
*) Fix SSL_peek:
