Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
+ *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
+ As these are not official, they are not included in "ALL";
+ the "ECCdraft" ciphersuite group alias can be used to select them.
+ [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
+
+ *) Add ECDH engine support.
+ [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
+
+ *) Add ECDH in new directory crypto/ecdh/.
+TODO: more general interface (return x coordinate, not its hash)
+TODO: bug: pad x with leading zeros if necessary
+ [Douglas Stebila (Sun Microsystems Laboratories)]
+
+ *) Let BN_rand_range() abort with an error after 100 iterations
+ without success (which indicates a broken PRNG).
+ [Bodo Moeller]
+
+ *) Change BN_mod_sqrt() so that it verifies that the input value
+ is really the square of the return value. (Previously,
+ BN_mod_sqrt would show GIGO behaviour.)
+ [Bodo Moeller]
+
+ *) Add named elliptic curves over binary fields from X9.62, SECG,
+ and WAP/WTLS; add OIDs that were still missing.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Extend the EC library for elliptic curves over binary fields
+ (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
+ New EC_METHOD:
+
+ EC_GF2m_simple_method
+
+ New API functions:
+
+ EC_GROUP_new_curve_GF2m
+ EC_GROUP_set_curve_GF2m
+ EC_GROUP_get_curve_GF2m
+ EC_POINT_set_affine_coordinates_GF2m
+ EC_POINT_get_affine_coordinates_GF2m
+ EC_POINT_set_compressed_coordinates_GF2m
+
+ Point compression for binary fields is disabled by default for
+ patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
+ enable it).
+
+ As binary polynomials are represented as BIGNUMs, various members
+ of the EC_GROUP and EC_POINT data structures can be shared
+ between the implementations for prime fields and binary fields;
+ the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
+ are essentially identical to their ..._GFp counterparts.
+ (For simplicity, the '..._GFp' prefix has been dropped from
+ various internal method names.)
+
+ An internal 'field_div' method (similar to 'field_mul' and
+ 'field_sqr') has been added; this is used only for binary fields.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
+ through methods ('mul', 'precompute_mult').
+
+ The generic implementations (now internally called 'ec_wNAF_mul'
+ and 'ec_wNAF_precomputed_mult') remain the default if these
+ methods are undefined.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) New function EC_GROUP_get_degree, which is defined through
+ EC_METHOD. For curves over prime fields, this returns the bit
+ length of the modulus.
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) New functions EC_GROUP_dup, EC_POINT_dup.
+ (These simply call ..._new and ..._copy).
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
+ Polynomials are represented as BIGNUMs (where the sign bit is not
+ used) in the following functions [macros]:
+
+ BN_GF2m_add
+ BN_GF2m_sub [= BN_GF2m_add]
+ BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
+ BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
+ BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
+ BN_GF2m_mod_inv
+ BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
+ BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
+ BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
+ BN_GF2m_cmp [= BN_ucmp]
+
+ (Note that only the 'mod' functions are actually for fields GF(2^m).
+ BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
+
+ For some functions, an the irreducible polynomial defining a
+ field can be given as an 'unsigned int[]' with strictly
+ decreasing elements giving the indices of those bits that are set;
+ i.e., p[] represents the polynomial
+ f(t) = t^p[0] + t^p[1] + ... + t^p[k]
+ where
+ p[0] > p[1] > ... > p[k] = 0.
+ This applies to the following functions:
+
+ BN_GF2m_mod_arr
+ BN_GF2m_mod_mul_arr
+ BN_GF2m_mod_sqr_arr
+ BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
+ BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
+ BN_GF2m_mod_exp_arr
+ BN_GF2m_mod_sqrt_arr
+ BN_GF2m_mod_solve_quad_arr
+ BN_GF2m_poly2arr
+ BN_GF2m_arr2poly
+
+ Conversion can be performed by the following functions:
+
+ BN_GF2m_poly2arr
+ BN_GF2m_arr2poly
+
+ bntest.c has additional tests for binary polynomial arithmetic.
+
+ Two implementations for BN_GF2m_mod_div() are available.
+ The default algorithm simply uses BN_GF2m_mod_inv() and
+ BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
+ if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
+ copyright notice in crypto/bn/bn_gf2m.c before enabling it).
+
+ [Sheueling Chang Shantz and Douglas Stebila
+ (Sun Microsystems Laboratories)]
+
+ *) Add new error code 'ERR_R_DISABLED' that can be used when some
+ functionality is disabled at compile-time.
+ [Douglas Stebila <douglas.stebila@sun.com>]
+
*) Change default behaviour of 'openssl asn1parse' so that more
information is visible when viewing, e.g., a certificate:
*) Add ECDSA in new directory crypto/ecdsa/.
- Add applications 'openssl ecdsaparam' and 'openssl ecdsa'
- (these are variants of 'openssl dsaparam' and 'openssl dsa').
+ Add applications 'openssl ecparam' and 'openssl ecdsa'
+ (these are based on 'openssl dsaparam' and 'openssl dsa').
ECDSA support is also included in various other files across the
library. Most notably,
- X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
them suitable for ECDSA where domain parameters must be
- extracted before the specific public key.
+ extracted before the specific public key;
+ - ECDSA engine support has been added.
[Nils Larsch <nla@trustcenter.de>]
*) Include some named elliptic curves, and add OIDs from X9.62,
EC_GROUP_get_nid()
[Nils Larsch <nla@trustcenter.de, Bodo Moeller]
- Changes between 0.9.6e and 0.9.7 [XX xxx 2002]
+ Changes between 0.9.6g and 0.9.7 [XX xxx 2002]
+
+ *) 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.
+ [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
+
+ *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
+ to allow version independent disabling of normally unselected ciphers,
+ which may be activated as a side-effect of selecting a single cipher.
+
+ (E.g., cipher list string "RSA" enables ciphersuites that are left
+ out of "ALL" because they do not provide symmetric encryption.
+ "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
+ [Lutz Jaenicke, Bodo Moeller]
+
+ *) Add appropriate support for separate platform-dependent build
+ directories. The recommended way to make a platform-dependent
+ build directory is the following (tested on Linux), maybe with
+ some local tweaks:
+
+ # Place yourself outside of the OpenSSL source tree. In
+ # this example, the environment variable OPENSSL_SOURCE
+ # is assumed to contain the absolute OpenSSL source directory.
+ mkdir -p objtree/`uname -s`-`uname -r`-`uname -m`
+ cd objtree/`uname -s`-`uname -r`-`uname -m`
+ (cd $OPENSSL_SOURCE; find . -type f -o -type l) | while read F; do
+ mkdir -p `dirname $F`
+ ln -s $OPENSSL_SOURCE/$F $F
+ done
+
+ To be absolutely sure not to disturb the source tree, a "make clean"
+ is a good thing. If it isn't successfull, don't worry about it,
+ it probably means the source directory is very clean.
+ [Richard Levitte]
*) Make sure any ENGINE control commands make local copies of string
pointers passed to them whenever necessary. Otherwise it is possible
*) Clean old EAY MD5 hack from e_os.h.
[Richard Levitte]
- Changes between 0.9.6d and 0.9.6e [XX xxx XXXX]
+ Changes between 0.9.6g and 0.9.6h [xx XXX xxxx]
+
+ *) Fix typo in OBJ_txt2obj which incorrectly passed the content
+ length, instead of the encoding length to d2i_ASN1_OBJECT.
+ [Steve Henson]
+
+ Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
+
+ *) [In 0.9.6g-engine release:]
+ Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
+ [Lynn Gazis <lgazis@rainbow.com>]
+
+ Changes between 0.9.6e and 0.9.6f [8 Aug 2002]
+
+ *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX
+ and get fix the header length calculation.
+ [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
+ Alon Kantor <alonk@checkpoint.com> (and others),
+ Steve Henson]
+
+ *) Use proper error handling instead of 'assertions' in buffer
+ overflow checks added in 0.9.6e. This prevents DoS (the
+ assertions could call abort()).
+ [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
+
+ Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
+
+ *) Add various sanity checks to asn1_get_length() to reject
+ the ASN1 length bytes if they exceed sizeof(long), will appear
+ negative or the content length exceeds the length of the
+ supplied buffer.
+ [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
*) Fix cipher selection routines: ciphers without encryption had no flags
for the cipher strength set and where therefore not handled correctly
applications.
[Bodo Moeller]
+ *) Changes in security patch:
+
+ Changes marked "(CHATS)" were sponsored by the Defense Advanced
+ Research Projects Agency (DARPA) and Air Force Research Laboratory,
+ Air Force Materiel Command, USAF, under agreement number
+ F30602-01-2-0537.
+
+ *) Add various sanity checks to asn1_get_length() to reject
+ the ASN1 length bytes if they exceed sizeof(long), will appear
+ negative or the content length exceeds the length of the
+ supplied buffer. (CAN-2002-0659)
+ [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
+
+ *) Assertions for various potential buffer overflows, not known to
+ happen in practice.
+ [Ben Laurie (CHATS)]
+
+ *) Various temporary buffers to hold ASCII versions of integers were
+ too small for 64 bit platforms. (CAN-2002-0655)
+ [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
+
+ *) Remote buffer overflow in SSL3 protocol - an attacker could
+ supply an oversized master key in Kerberos-enabled versions.
+ (CAN-2002-0657)
+ [Ben Laurie (CHATS)]
+
+ *) Remote buffer overflow in SSL3 protocol - an attacker could
+ supply an oversized session ID to a client. (CAN-2002-0656)
+ [Ben Laurie (CHATS)]
+
+ *) Remote buffer overflow in SSL2 protocol - an attacker could
+ supply an oversized client master key. (CAN-2002-0656)
+ [Ben Laurie (CHATS)]
+
Changes between 0.9.6c and 0.9.6d [9 May 2002]
*) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
