Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
+ *) Extend the BIGNUM API by creating new macros that behave like
+ functions
+
+ void BN_set_sign(BIGNUM *a, int neg);
+ int BN_get_sign(const BIGNUM *a);
+
+ and avoid the need to access 'a->neg' directly in applications.
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Implement fast modular reduction for pseudo-Mersenne primes
+ used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
+ EC_GROUP_new_curve_GFp() will now automatically use this
+ if applicable.
+ [Nils Larsch <nla@trustcenter.de>]
+
+ *) Add new lock type (CRYPTO_LOCK_BN).
+ [Bodo Moeller]
+
+ *) Change the ENGINE framework to automatically load engines
+ dynamically from specific directories unless they could be
+ found to already be built in or loaded. Move all the
+ current engines except for the cryptodev one to a new
+ directory engines/.
+ The engines in engines/ are built as shared libraries if
+ the "shared" options was given to ./Configure or ./config.
+ Otherwise, they are inserted in libcrypto.a.
+ /usr/local/ssl/engines is the default directory for dynamic
+ engines, but that can be overriden at configure time through
+ the usual use of --prefix and/or --openssldir, and at run
+ time with the environment variable OPENSSL_ENGINES.
+ [Geoff Thorpe and Richard Levitte]
+
+ *) Add Makefile.shared, a helper makefile to build shared
+ libraries. Addapt Makefile.org.
+ [Richard Levitte]
+
+ *) Add version info to Win32 DLLs.
+ [Peter 'Luna' Runestig" <peter@runestig.com>]
+
+ *) Add new 'medium level' PKCS#12 API. Certificates and keys
+ can be added using this API to created arbitrary PKCS#12
+ files while avoiding the low level API.
+
+ New options to PKCS12_create(), key or cert can be NULL and
+ will then be omitted from the output file. The encryption
+ algorithm NIDs can be set to -1 for no encryption, the mac
+ iteration count can be set to 0 to omit the mac.
+
+ Enhance pkcs12 utility by making the -nokeys and -nocerts
+ options work when creating a PKCS#12 file. New option -nomac
+ to omit the mac, NONE can be set for an encryption algorithm.
+ New code is modified to use the enhanced PKCS12_create()
+ instead of the low level API.
+ [Steve Henson]
+
+ *) Extend ASN1 encoder to support indefinite length constructed
+ encoding. This can output sequences tags and octet strings in
+ this form. Modify pk7_asn1.c to support indefinite length
+ encoding. This is experimental and needs additional code to
+ be useful, such as an ASN1 bio and some enhanced streaming
+ PKCS#7 code.
+
+ Extend template encode functionality so that tagging is passed
+ down to the template encoder.
+ [Steve Henson]
+
*) Let 'openssl req' fail if an argument to '-newkey' is not
recognized instead of using RSA as a default.

- Changes between 0.9.6g and 0.9.7 [XX xxx 2002]
+ Changes between 0.9.6h and 0.9.7 [XX xxx 2002]
+
+ *) Introduce safe string copy and catenation functions
+ (BUF_strlcpy() and BUF_strlcat()).
+ [Ben Laurie (CHATS) and Richard Levitte]
+
+ *) Avoid using fixed-size buffers for one-line DNs.
+ [Ben Laurie (CHATS)]
+
+ *) Add BUF_MEM_grow_clean() to avoid information leakage when
+ resizing buffers containing secrets, and use where appropriate.
+ [Ben Laurie (CHATS)]
+
+ *) Avoid using fixed size buffers for configuration file location.
+ [Ben Laurie (CHATS)]
+
+ *) Avoid filename truncation for various CA files.
+ [Ben Laurie (CHATS)]
+
+ *) Use sizeof in preference to magic numbers.
+ [Ben Laurie (CHATS)]
+
+ *) Avoid filename truncation in cert requests.
+ [Ben Laurie (CHATS)]
+
+ *) Add assertions to check for (supposedly impossible) buffer
+ overflows.
+ [Ben Laurie (CHATS)]
+
+ *) Don't cache truncated DNS entries in the local cache (this could
+ potentially lead to a spoofing attack).
+ [Ben Laurie (CHATS)]
+
+ *) Fix various buffers to be large enough for hex/decimal
+ representations in a platform independent manner.
+ [Ben Laurie (CHATS)]
+
+ *) Add CRYPTO_realloc_clean() to avoid information leakage when
+ resizing buffers containing secrets, and use where appropriate.
+ [Ben Laurie (CHATS)]
+
+ *) Add BIO_indent() to avoid much slightly worrying code to do
+ indents.
+ [Ben Laurie (CHATS)]
+
+ *) Convert sprintf()/BIO_puts() to BIO_printf().
+ [Ben Laurie (CHATS)]
+
+ *) buffer_gets() could terminate with the buffer only half
+ full. Fixed.
+ [Ben Laurie (CHATS)]
+
+ *) Add assertions to prevent user-supplied crypto functions from
+ overflowing internal buffers by having large block sizes, etc.
+ [Ben Laurie (CHATS)]
+
+ *) New OPENSSL_assert() macro (similar to assert(), but enabled
+ unconditionally).
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused copy of key in RC4.
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and incorrectly sized buffers for IV in pem.h.
+ [Ben Laurie (CHATS)]
+
+ *) Fix off-by-one error in EGD path.
+ [Ben Laurie (CHATS)]
+
+ *) If RANDFILE path is too long, ignore instead of truncating.
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and incorrectly sized X.509 structure
+ CBCParameter.
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and dangerous function knumber().
+ [Ben Laurie (CHATS)]
+
+ *) Eliminate unused and dangerous structure, KSSL_ERR.
+ [Ben Laurie (CHATS)]
+
+ *) Protect against overlong session ID context length in an encoded
+ session object. Since these are local, this does not appear to be
+ exploitable.
+ [Ben Laurie (CHATS)]
+
+ *) Change from security patch (see 0.9.6e below) that did not affect
+ the 0.9.6 release series:
+
+ Remote buffer overflow in SSL3 protocol - an attacker could
+ supply an oversized master key in Kerberos-enabled versions.
+ (CAN-2002-0657)
+ [Ben Laurie (CHATS)]
+
+ *) Change the SSL kerb5 codes to match RFC 2712.
+ [Richard Levitte]
*) Make -nameopt work fully for req and add -reqopt switch.
[Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
*) The "block size" for block ciphers in CFB and OFB mode should be 1.

- *) The "block size" for block ciphers in CFB and OFB mode should be 1.

*) Make sure tests can be performed even if the corresponding algorithms
have been removed entirely. This was also the last step to make
OpenSSL compilable with DJGPP under all reasonable conditions.
# Place yourself outside of the OpenSSL source tree. In

- *) Fix race condition in SSLv3_client_method().
- [Bodo Moeller]
+ *) Fix client_certificate (ssl/s2_clnt.c): The permissible total
+ length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
+ [Zeev Lieber <zeev-l@yahoo.com>]
+
+ *) Undo an undocumented change introduced in 0.9.6e which caused
+ repeated calls to OpenSSL_add_all_ciphers() and
+ OpenSSL_add_all_digests() to be ignored, even after calling
+ EVP_cleanup().
+ [Richard Levitte]
+
+ *) Change the default configuration reader to deal with last line not
+ being properly terminated.
+ [Richard Levitte]
+
+ *) Change X509_NAME_cmp() so it applies the special rules on handling
+ DN values that are of type PrintableString, as well as RDNs of type
+ emailAddress where the value has the type ia5String.
+ [stefank@valicert.com via Richard Levitte]
+
+ *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
+ the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
+ doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
+ the bitwise-OR of the two for use by the majority of applications
+ wanting this behaviour, and update the docs. The documented
+ behaviour and actual behaviour were inconsistent and had been
+ changing anyway, so this is more a bug-fix than a behavioural
+ change.
+ [Geoff Thorpe, diagnosed by Nadav Har'El]
+
+ *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
+ (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
+ [Bodo Moeller]
+
+ *) Fix initialization code race conditions in
+ SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
+ SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),
+ SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(),

+ ssl2_get_cipher_by_char(),
+ ssl3_get_cipher_by_char().
+ [Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
*) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
the cached sessions are flushed, as the remove_cb() might use ex_data
overflow checks added in 0.9.6e. This prevents DoS (the
assertions could call abort()).
