The initial serial + number file is now moved from CA.pl to the 'ca' utility with a new + option -create_serial. + [Steve Henson] + + *) Reduced header interdepencies by declaring more opaque objects in + ossl_typ.h. As a consequence, including some headers (eg. engine.h) will + give fewer recursive includes, which could break lazy source code - so + this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, + developers should define this symbol when building and using openssl to + ensure they track the recommended behaviour, interfaces, [etc], but + backwards-compatible behaviour prevails when this isn't defined. + [Geoff Thorpe] + + *) New function X509_POLICY_NODE_print() which prints out policy nodes. + [Steve Henson] + + *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. + This will generate a random key of the appropriate length based on the + cipher context. The EVP_CIPHER can provide its own random key generation + routine to support keys of a specific form. This is used in the des and + 3des routines to generate a key of the correct parity. Update S/MIME + code to use new functions and hence generate correct parity DES keys. + Add EVP_CHECK_DES_KEY #define to return an error if the key is not + valid (weak or incorrect parity). + [Steve Henson] + + *) Add a local set of CRLs that can be used by X509_verify_cert() as well + as looking them up. This is useful when the verified structure may contain + CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs + present unless the new PKCS7_NO_CRL flag is asserted. + [Steve Henson] + + *) Extend ASN1 oid configuration module. It now additionally accepts the + syntax: + + shortName = some long name, 1.2.3.4 + [Steve Henson] + + *) Reimplemented the BN_CTX implementation. There is now no more static + limitation on the number of variables it can handle nor the depth of the + "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack + information can now expand as required, and rather than having a single + static array of bignums, BN_CTX now uses a linked-list of such arrays + allowing it to expand on demand whilst maintaining the usefulness of + BN_CTX's "bundling". + [Geoff Thorpe] + + *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD + to allow all RSA operations to function using a single BN_CTX. + [Geoff Thorpe] + + *) Preliminary support for certificate policy evaluation and checking. This + is initially intended to pass the tests outlined in "Conformance Testing + of Relying Party Client Certificate Path Processing Logic" v1.07. + [Steve Henson] + + *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and + remained unused and not that useful. A variety of other little bignum + tweaks and fixes have also been made continuing on from the audit (see + below). + [Geoff Thorpe] + + *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with + associated ASN1, EVP and SSL functions and old ASN1 macros. + [Richard Levitte] + + *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, + and this should never fail. So the return value from the use of + BN_set_word() (which can fail due to needless expansion) is now deprecated; + if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. + [Geoff Thorpe] + + *) BN_CTX_get() should return zero-valued bignums, providing the same + initialised value as BN_new(). + [Geoff Thorpe, suggested by Ulf Möller] + + *) Support for inhibitAnyPolicy certificate extension. + [Steve Henson] + *) An audit of the BIGNUM code is underway, for which debugging code is enabled when BN_DEBUG is defined.
