Update Changelog for DH params
Add test case for dh params with privateValueLength
accept PKCS#3 DH parameters with privateValueLength included
Conflicts:
library/dhm.c
library/dhm.c: accept (and ignore) optional privateValueLength for
PKCS#3 DH parameters.
PKCS#3 defines the ASN.1 encoding of a DH parameter set like this:
----------------
DHParameter ::= SEQUENCE {
prime INTEGER, -- p
base INTEGER, -- g
privateValueLength INTEGER OPTIONAL }
The fields of type DHParameter have the following meanings:
o prime is the prime p.
o base is the base g.
o privateValueLength is the optional private-value
length l.
----------------
See: ftp://ftp.rsasecurity.com/pub/pkcs/ascii/pkcs-3.asc
This optional parameter was added in PKCS#3 version 1.4, released
November 1, 1993.
dhm.c currently doesn't cope well with PKCS#3 files that have this
optional final parameter included. i see errors like:
------------
dhm_parse_dhmfile returned -0x33E6
Last error was: -0x33E6 - DHM - The ASN.1 data is not formatted correctly : ASN1 - Actual length differs from expected lengt
------------
You can generate PKCS#3 files with this final parameter with recent
versions of certtool from GnuTLS:
certtool --generate-dh-params > dh.pem
code selection
The base RFC 4279 DHE-PSK ciphersuites are now supported and added.
The SSL code cuts out code not relevant for defined key exchange methods
- The error codes have been remapped and combining error codes is now done with a PLUS instead of an OR as error codes used are negative.
- Descriptions to all error codes have been added.
- Generation script for error.c has been created to automatically generate error.c from the available error definitions in the headers.
