+ *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
+ [Lutz Jaenicke]
+
+ +) Add EVP test program.
+ [Ben Laurie]
+
+ +) Add symmetric cipher support to ENGINE. Expect the API to change!
+ [Ben Laurie]
+
+ +) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
+ X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
+ X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
+ These allow a CRL to be built without having to access X509_CRL fields
+ directly. Modify 'ca' application to use new functions.
+ [Steve Henson]
+
+ *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
+ for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
+ [Lutz Jaenicke]
+
+ *) Rework the configuration and shared library support for Tru64 Unix.
+ The configuration part makes use of modern compiler features and
+ still retains old compiler behavior for those that run older versions
+ of the OS. The shared library support part includes a variant that
+ uses the RPATH feature, and is available through the speciel
+ configuration target "alpha-cc-rpath", which will never be selected
+ automatically.
+ [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
+
+ *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
+ with the same message size as in ssl3_get_certificate_request().
+ Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
+ messages might inadvertently be reject as too long.
+ [Petr Lampa <lampa@fee.vutbr.cz>]
+
+ +) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
+ bug workarounds. Rollback attack detection is a security feature.
+ The problem will only arise on OpenSSL servers when TLSv1 is not
+ available (sslv3_server_method() or SSL_OP_NO_TLSv1).
+ Software authors not wanting to support TLSv1 will have special reasons
+ for their choice and can explicitly enable this option.
+ [Bodo Moeller, Lutz Jaenicke]
+
+ +) Rationalise EVP so it can be extended: don't include a union of
+ cipher/digest structures, add init/cleanup functions. This also reduces
+ the number of header dependencies.
+ [Ben Laurie]
+
+ +) Make DES key schedule conform to the usual scheme, as well as
+ correcting its structure. This means that calls to DES functions
+ now have to pass a pointer to a des_key_schedule instead of a
+ plain des_key_schedule (which was actually always a pointer
+ anyway).
+ [Ben Laurie]
+
+ +) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
+ [Andy Polyakov]
+
+ *) Modified SSL library such that the verify_callback that has been set
+ specificly for an SSL object with SSL_set_verify() is actually being
+ used. Before the change, a verify_callback set with this function was
+ ignored and the verify_callback() set in the SSL_CTX at the time of
+ the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
+ to allow the necessary settings.
+ [Lutz Jaenicke]
+
+ +) Initial reduction of linker bloat: the use of some functions, such as
+ PEM causes large amounts of unused functions to be linked in due to
+ poor organisation. For example pem_all.c contains every PEM function
+ which has a knock on effect of linking in large amounts of (unused)
+ ASN1 code. Grouping together similar functions and splitting unrelated
+ functions prevents this.
+ [Steve Henson]
+
+ *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
+ explicitely to NULL, as at least on Solaris 8 this seems not always to be
+ done automatically (in contradiction to the requirements of the C
+ standard). This made problems when used from OpenSSH.
+ [Lutz Jaenicke]
+
+ *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
+ dh->length and always used
+
+ BN_rand_range(priv_key, dh->p).
+
+ BN_rand_range() is not necessary for Diffie-Hellman, and this
+ specific range makes Diffie-Hellman unnecessarily inefficient if
+ dh->length (recommended exponent length) is much smaller than the
+ length of dh->p. We could use BN_rand_range() if the order of
+ the subgroup was stored in the DH structure, but we only have
+ dh->length.
+
+ So switch back to
+
+ BN_rand(priv_key, l, ...)
+
+ where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
+ otherwise.
+ [Bodo Moeller]
+
+ *) In
+
+ RSA_eay_public_encrypt
+ RSA_eay_private_decrypt
+ RSA_eay_private_encrypt (signing)
+ RSA_eay_public_decrypt (signature verification)
+
+ (default implementations for RSA_public_encrypt,
+ RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
+ always reject numbers >= n.
+ [Bodo Moeller]
+
+ *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
+ to synchronize access to 'locking_thread'. This is necessary on
+ systems where access to 'locking_thread' (an 'unsigned long'
+ variable) is not atomic.
+ [Bodo Moeller]
+
+ *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
+ *before* setting the 'crypto_lock_rand' flag. The previous code had
+ a race condition if 0 is a valid thread ID.
+ [Travis Vitek <vitek@roguewave.com>]
+
+ +) Cleanup of EVP macros.
+ [Ben Laurie]
+
+ +) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
+ correct _ecb suffix.
+ [Ben Laurie]
+
+ +) Add initial OCSP responder support to ocsp application. The
+ revocation information is handled using the text based index
+ use by the ca application. The responder can either handle
+ requests generated internally, supplied in files (for example
+ via a CGI script) or using an internal minimal server.
+ [Steve Henson]
+
+ +) Add configuration choices to get zlib compression for TLS.
+ [Richard Levitte]
+
+ +) Changes to Kerberos SSL for RFC 2712 compliance:
+ 1. Implemented real KerberosWrapper, instead of just using
+ KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
+ 2. Implemented optional authenticator field of KerberosWrapper.
+
+ Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
+ and authenticator structs; see crypto/krb5/.
+
+ Generalized Kerberos calls to support multiple Kerberos libraries.
+ [Vern Staats <staatsvr@asc.hpc.mil>,

+ via Richard Levitte]
+
+ +) Cause 'openssl speed' to use fully hard-coded DSA keys as it
+ already does with RSA. testdsa.h now has 'priv_key/pub_key'
+ values for each of the key sizes rather than having just
+ parameters (and 'speed' generating keys each time).
+ [Geoff Thorpe]
+
+ -) OpenSSL 0.9.6b released [9 July 2001]
+
+ *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
+ to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
+ Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
+ PRNG state recovery was possible based on the output of
+ one PRNG request appropriately sized to gain knowledge on
+ 'md' followed by enough consecutive 1-byte PRNG requests
+ to traverse all of 'state'.
+
+ 1. When updating 'md_local' (the current thread's copy of 'md')
+ during PRNG output generation, hash all of the previous
+ 'md_local' value, not just the half used for PRNG output.
+
+ 2. Make the number of bytes from 'state' included into the hash
+ independent from the number of PRNG bytes requested.
+
+ The first measure alone would be sufficient to avoid
+ Markku-Juhani's attack. (Actually it had never occurred
+ to me that the half of 'md_local' used for chaining was the
+ half from which PRNG output bytes were taken -- I had always
+ assumed that the secret half would be used.) The second
+ measure makes sure that additional data from 'state' is never
+ mixed into 'md_local' in small portions; this heuristically
+ further strengthens the PRNG.

+ ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]

+ +) Rewrite apps to use NCONF routines instead of the old CONF. New functions
+ to support NCONF routines in extension code. New function CONF_set_nconf()
+ to allow functions which take an NCONF to also handle the old LHASH
+ structure: this means that the old CONF compatible routines can be
+ retained (in particular wrt extensions) without having to duplicate the
+ code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
+ [Steve Henson]
+

+ [Verdon Walker <VWalker@novell.com>, Steve Henson]
+
+ +) Add the possibility to control engines through control names but with
+ arbitrary arguments instead of just a string.
+ Change the key loaders to take a UI_METHOD instead of a callback
+ function pointer. NOTE: this breaks binary compatibility with earlier
+ versions of OpenSSL [engine].
+ Addapt the nCipher code for these new conditions and add a card insertion
+ callback.
+ [Richard Levitte]
+
+ +) Enhance the general user interface with mechanisms to better support
+ dialog box interfaces, application-defined prompts, the possibility
+ to use defaults (for example default passwords from somewhere else)
+ and interrupts/cancelations.
+ [Richard Levitte]
+
+ *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
