See crypto/rc4/rc4_enc.c for further details. + [Andy Polyakov] + + *) New -noout option to asn1parse. This causes no output to be produced + its main use is when combined with -strparse and -out to extract data + from a file (which may not be in ASN.1 format). + [Steve Henson] + + *) Fix for pkcs12 program. It was hashing an invalid certificate pointer + when producing the local key id. + [Richard Levitte ] + + *) New option -dhparam in s_server. This allows a DH parameter file to be + stated explicitly. If it is not stated then it tries the first server + certificate file. The previous behaviour hard coded the filename + "server.pem". + [Steve Henson] + + *) Add -pubin and -pubout options to the rsa and dsa commands. These allow + a public key to be input or output. For example: + openssl rsa -in key.pem -pubout -out pubkey.pem + Also added necessary DSA public key functions to handle this. + [Steve Henson] + + *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained + in the message. This was handled by allowing + X509_find_by_issuer_and_serial() to tolerate a NULL passed to it. + [Steve Henson, reported by Sampo Kellomaki ] + + *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null + to the end of the strings whereas this didn't. This would cause problems + if strings read with d2i_ASN1_bytes() were later modified. + [Steve Henson, reported by Arne Ansper ] + + *) Fix for base64 decode bug. When a base64 bio reads only one line of + data and it contains EOF it will end up returning an error. This is + caused by input 46 bytes long. The cause is due to the way base64 + BIOs find the start of base64 encoded data. They do this by trying a + trial decode on each line until they find one that works. When they + do a flag is set and it starts again knowing it can pass all the + data directly through the decoder. Unfortunately it doesn't reset + the context it uses. This means that if EOF is reached an attempt + is made to pass two EOFs through the context and this causes the + resulting error. This can also cause other problems as well. As is + usual with these problems it takes *ages* to find and the fix is + trivial: move one line. + [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ] + + *) Ugly workaround to get s_client and s_server working under Windows. The + old code wouldn't work because it needed to select() on sockets and the + tty (for keypresses and to see if data could be written). Win32 only + supports select() on sockets so we select() with a 1s timeout on the + sockets and then see if any characters are waiting to be read, if none + are present then we retry, we also assume we can always write data to + the tty. This isn't nice because the code then blocks until we've + received a complete line of data and it is effectively polling the + keyboard at 1s intervals: however it's quite a bit better than not + working at all :-) A dedicated Windows application might handle this + with an event loop for example. + [Steve Henson] + + *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign + and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions + will be called when RSA_sign() and RSA_verify() are used. This is useful + if rsa_pub_dec() and rsa_priv_enc() equivalents are not available. + For this to work properly RSA_public_decrypt() and RSA_private_encrypt() + should *not* be used: RSA_sign() and RSA_verify() must be used instead. + This necessitated the support of an extra signature type NID_md5_sha1 + for SSL signatures and modifications to the SSL library to use it instead + of calling RSA_public_decrypt() and RSA_private_encrypt(). + [Steve Henson] + + *) Add new -verify -CAfile and -CApath options to the crl program, these + will lookup a CRL issuers certificate and verify the signature in a + similar way to the verify program. Tidy up the crl program so it + no longer acesses structures directly. Make the ASN1 CRL parsing a bit + less strict. It will now permit CRL extensions even if it is not + a V2 CRL: this will allow it to tolerate some broken CRLs. + [Steve Henson] + + *) Initialize all non-automatic variables each time one of the openssl + sub-programs is started (this is necessary as they may be started + multiple times from the "OpenSSL>" prompt). + [Lennart Bang, Bodo Moeller] + + *) Preliminary compilation option RSA_NULL which disables RSA crypto without + removing all other RSA functionality (this is what NO_RSA does). This + is so (for example) those in the US can disable those operations covered + by the RSA patent while allowing storage and parsing of RSA keys and RSA + key generation. + [Steve Henson] + + *) Non-copying interface to BIO pairs. + (still largely untested) + [Bodo Moeller] + + *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive + ASCII string. This was handled independently in various places before. + [Steve Henson] + + *) New functions UTF8_getc() and UTF8_putc() that parse and generate + UTF8 strings a character at a time. + [Steve Henson] + + *) Use client_version from client hello to select the protocol + (s23_srvr.c) and for RSA client key exchange verification + (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications. + [Bodo Moeller] + + *) Add various utility functions to handle SPKACs, these were previously + handled by poking round in the structure internals. Added new function + NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to + print, verify and generate SPKACs. Based on an original idea from + Massimiliano Pala but extensively modified. + [Steve Henson] + + *) RIPEMD160 is operational on all platforms and is back in 'make test'. + [Andy Polyakov] + + *) Allow the config file extension section to be overwritten on the + command line. Based on an original idea from Massimiliano Pala + . The new option is called -extensions + and can be applied to ca, req and x509. Also -reqexts to override + the request extensions in req and -crlexts to override the crl extensions + in ca. + [Steve Henson] + + *) Add new feature to the SPKAC handling in ca. Now you can include + the same field multiple times by preceding it by "XXXX." for example: + 1.OU="Unit name 1" + 2.OU="Unit name 2" + this is the same syntax as used in the req config file. + [Steve Henson] + + *) Allow certificate extensions to be added to certificate requests. These + are specified in a 'req_extensions' option of the req section of the + config file. They can be printed out with the -text option to req but + are otherwise ignored at present. + [Steve Henson] + + *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first + data read consists of only the final block it would not decrypted because + EVP_CipherUpdate() would correctly report zero bytes had been decrypted. + A misplaced 'break' also meant the decrypted final block might not be + copied until the next read. + [Steve Henson] + + *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added + a few extra parameters to the DH structure: these will be useful if + for example we want the value of 'q' or implement X9.42 DH. + [Steve Henson] + *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and provides hooks that allow the default DSA functions or functions on a "per key" basis to be replaced.
