OpenSSL CHANGES
_______________
- Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
+ Changes between 0.9.6h and 0.9.7 [XX xxx 2002]
- *) 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:
-
- Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
- mode the content of non-printable OCTET STRINGs is output in a
- style similar to INTEGERs, but with '[HEX DUMP]' prepended to
- avoid the appearance of a printable string.
- [Nils Larsch <nla@trustcenter.de>]
+ *) Make -nameopt work fully for req and add -reqopt switch.
+ [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
- *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
- functions
- EC_GROUP_set_asn1_flag()
- EC_GROUP_get_asn1_flag()
- EC_GROUP_set_point_conversion_form()
- EC_GROUP_get_point_conversion_form()
- These control ASN1 encoding details:
- - Curves (i.e., groups) are encoded explicitly unless asn1_flag
- has been set to OPENSSL_EC_NAMED_CURVE.
- - Points are encoded in uncompressed form by default; options for
- asn1_for are as for point2oct, namely
- POINT_CONVERSION_COMPRESSED
- POINT_CONVERSION_UNCOMPRESSED
- POINT_CONVERSION_HYBRID
-
- Also add 'seed' and 'seed_len' members to EC_GROUP with access
- functions
- EC_GROUP_set_seed()
- EC_GROUP_get0_seed()
- EC_GROUP_get_seed_len()
- This is used only for ASN1 purposes (so far).
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Add 'field_type' member to EC_METHOD, which holds the NID
- of the appropriate field type OID. The new function
- EC_METHOD_get_field_type() returns this value.
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Add functions
- EC_POINT_point2bn()
- EC_POINT_bn2point()
- EC_POINT_point2hex()
- EC_POINT_hex2point()
- providing useful interfaces to EC_POINT_point2oct() and
- EC_POINT_oct2point().
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Change internals of the EC library so that the functions
- EC_GROUP_set_generator()
- EC_GROUP_get_generator()
- EC_GROUP_get_order()
- EC_GROUP_get_cofactor()
- are implemented directly in crypto/ec/ec_lib.c and not dispatched
- to methods, which would lead to unnecessary code duplication when
- adding different types of curves.
- [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
-
- *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
- arithmetic, and such that modified wNAFs are generated
- (which avoid length expansion in many cases).
- [Bodo Moeller]
-
- *) Add a function EC_GROUP_check_discriminant() (defined via
- EC_METHOD) that verifies that the curve discriminant is non-zero.
-
- Add a function EC_GROUP_check() that makes some sanity tests
- on a EC_GROUP, its generator and order. This includes
- EC_GROUP_check_discriminant().
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Add ECDSA in new directory crypto/ecdsa/.
-
- 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,
- - 'openssl req' now has a '-newkey ecdsa:file' option;
- - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
- - 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.
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Include some named elliptic curves, and add OIDs from X9.62,
- SECG, and WAP/WTLS. The curves can be obtained from the new
- functions
- EC_GROUP_new_by_nid()
- EC_GROUP_new_by_name()
- Also add a 'curve_name' member to EC_GROUP objects, which can be
- accessed via
- EC_GROUP_set_nid()
- EC_GROUP_get_nid()
- [Nils Larsch <nla@trustcenter.de, Bodo Moeller]
-
- Changes between 0.9.6e and 0.9.7 [XX xxx 2002]
+ *) The "block size" for block ciphers in CFB and OFB mode should be 1.
+ [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
*) Make sure tests can be performed even if the corresponding algorithms
have been removed entirely. This was also the last step to make
# 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.

[Richard Levitte]
- Changes between 0.9.6e and 0.9.6f [XX xxx XXXX]
+ Changes between 0.9.6g and 0.9.6h [xx XXX xxxx]
+
+ *) 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
+ contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
+ (see [openssl.org #212]).
+ [Geoff Thorpe, Lutz Jaenicke]
+
+ *) 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.
