Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
+ *) 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>]
+
+ *) 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()
*) 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,
functions
EC_GROUP_new_by_nid()
EC_GROUP_new_by_name()
- Also add a 'nid' field to EC_GROUP objects, which can be accessed
- via
+ 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 0.9.6d and 0.9.7 [XX xxx 2002]
+ Changes between 0.9.6e 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
+ the caller may have overwritten (or deallocated) the original string
+ data when a later ENGINE operation tries to use the stored values.
+ [Götz Babin-Ebell <babinebell@trustcenter.de>]
+
+ *) Improve diagnostics in file reading and command-line digests.
+ [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
+
+ *) Add AES modes CFB and OFB to the object database. Correct an
+ error in AES-CFB decryption.
+ [Richard Levitte]
*) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
allows existing EVP_CIPHER_CTX structures to be reused after
form for "surname", serialNumber has no short form.
Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
therefore remove "mail" short name for "internet 7".
+ The OID for unique identifiers in X509 certificates is
+ x500UniqueIdentifier, not uniqueIdentifier.
Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
[Lutz Jaenicke]
By default, clients may request session resumption even during
renegotiation (if session ID contexts permit); with this option,
session resumption is possible only in the first handshake.
+
+ SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes
+ more bits available for options that should not be part of
+ SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
[Bodo Moeller]
*) Add some demos for certificate and certificate request creation.
[Bodo Moeller, Lutz Jaenicke]
*) Rationalise EVP so it can be extended: don't include a union of
- cipher/digest structures, add init/cleanup functions. This also reduces
- the number of header dependencies.
+ cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
+ (similar to those existing for EVP_CIPHER_CTX).
Usage example:
EVP_MD_CTX md;
handle the new API. Currently only ECB, CBC modes supported. Add new
AES OIDs.
- Add TLS AES ciphersuites as described in the "AES Ciphersuites
- for TLS" draft-ietf-tls-ciphersuite-06.txt. As these are not yet
- official, they are not enabled by default and are not even part
- of the "ALL" ciphersuite alias; for now, they must be explicitly
- requested by specifying the new "AESdraft" ciphersuite alias. If
- you want the default ciphersuite list plus the new ciphersuites,
- use "DEFAULT:AESdraft:@STRENGTH".
- [Ben Laurie, Steve Henson, Bodo Moeller]
+ Add TLS AES ciphersuites as described in RFC3268, "Advanced
+ Encryption Standard (AES) Ciphersuites for Transport Layer
+ Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were
+ not enabled by default and were not part of the "ALL" ciphersuite
+ alias because they were not yet official; they could be
+ explicitly requested by specifying the "AESdraft" ciphersuite
+ group alias. In the final release of OpenSSL 0.9.7, the group
+ alias is called "AES" and is part of "ALL".)
+ [Ben Laurie, Steve Henson, Bodo Moeller]
*) New function OCSP_copy_nonce() to copy nonce value (if present) from
request to response.
*) 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 0.9.6d 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
+ by the selection routines (PR #130).
+ [Lutz Jaenicke]
*) Fix EVP_dsa_sha macro.
[Nils Larsch]
+ *) New option
+ SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
+ for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
+ that was added in OpenSSL 0.9.6d.
+
+ As the countermeasure turned out to be incompatible with some
+ broken SSL implementations, the new option is part of SSL_OP_ALL.
+ SSL_OP_ALL is usually employed when compatibility with weird SSL
+ implementations is desired (e.g. '-bugs' option to 's_client' and
+ 's_server'), so the new option is automatically set in many
+ 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
