It is similar to -WWW, but requires + that the file contains a complete HTTP response. + [Richard Levitte] + + *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl + change the def and num file printf format specifier from "%-40sXXX" + to "%-39s XXX". The latter will always guarantee a space after the + field while the former will cause them to run together if the field + is 40 of more characters long. + [Steve Henson] + + *) Constify the cipher and digest 'method' functions and structures + and modify related functions to take constant EVP_MD and EVP_CIPHER + pointers. + [Steve Henson] + + *) Implement ssl23_peek (analogous to ssl23_read), which previously + did not exist. + [Bodo Moeller] + + *) Replace rdtsc with _emit statements for VC++ version 5. + [Jeremy Cooper ] + + *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them + in . Also further increase BN_CTX_NUM to 32. + [Bodo Moeller] + + *) Modify EVP_Digest*() routines so they now return values. Although the + internal software routines can never fail additional hardware versions + might. + [Steve Henson] + + *) Clean up crypto/err/err.h and change some error codes to avoid conflicts: + + Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 + (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. + + ASN1 error codes + ERR_R_NESTED_ASN1_ERROR + ... + ERR_R_MISSING_ASN1_EOS + were 4 .. 9, conflicting with + ERR_LIB_RSA (= ERR_R_RSA_LIB) + ... + ERR_LIB_PEM (= ERR_R_PEM_LIB). + They are now 58 .. 63 (i.e., just below ERR_R_FATAL). + + Add new error code 'ERR_R_INTERNAL_ERROR'. + [Bodo Moeller] + + *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock + suffices. + [Bodo Moeller] + + *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This + sets the subject name for a new request or supersedes the + subject name in a given request. Formats that can be parsed are + 'CN=Some Name, OU=myOU, C=IT' + and + 'CN=Some Name/OU=myOU/C=IT'. + + Add options '-batch' and '-verbose' to 'openssl req'. + [Massimiliano Pala ] + + *) Make it possible to reuse SSLv2 sessions. + [Richard Levitte] + + *) Introduce the possibility to access global variables through + functions on platform were that's the best way to handle exporting + global variables in shared libraries. To enable this functionality, + one must configure with "EXPORT_VAR_AS_FN" or defined the C macro + "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter + is normally done by Configure or something similar). + + To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL + in the source file (foo.c) like this: + + OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; + OPENSSL_IMPLEMENT_GLOBAL(double,bar); + + To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL + and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: + + OPENSSL_DECLARE_GLOBAL(int,foo); + #define foo OPENSSL_GLOBAL_REF(foo) + OPENSSL_DECLARE_GLOBAL(double,bar); + #define bar OPENSSL_GLOBAL_REF(bar) + + The #defines are very important, and therefore so is including the + header file everywere where the defined globals are used. + + The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition + of ASN.1 items, but that structure is a bt different. + + The largest change is in util/mkdef.pl which has been enhanced with + better and easier to understand logic to choose which symbols should + go into the Windows .def files as well as a number of fixes and code + cleanup (among others, algorithm keywords are now sorted + lexicographically to avoid constant rewrites). + [Richard Levitte] + + *) In copy_email() check for >= 0 as a return value for + X509_NAME_get_index_by_NID() since 0 is a valid index. + [Steve Henson reported by Massimiliano Pala ] + + *) In BN_div() keep a copy of the sign of 'num' before writing the + result to 'rm' because if rm==num the value will be overwritten + and produce the wrong result if 'num' is negative: this caused + problems with BN_mod() and BN_nnmod(). + [Steve Henson] + + *) Function OCSP_request_verify(). This checks the signature on an + OCSP request and verifies the signer certificate. The signer + certificate is just checked for a generic purpose and OCSP request + trust settings. + [Steve Henson] + *) Add OCSP_check_validity() function to check the validity of OCSP responses. OCSP responses are prepared in real time and may only be a few seconds old. Simply checking that the current time lies
