Hi.
I am writing some C++ on Linux with g++. When I try to link statically to
libcrypto, by using the libcrypto.a library, it complains that RSA_generate_key
and DH_generate_parameters are undefined references. Actually, I believe it
said that openldap.so was complaining that they were undefin

Hi All,
I would like to know whether openssl API has function call for generating
ECC point-compression given that only the uncompressed ECC public key.
Likewise, given the point-compressed ECC Key, I would also like to recover
the uncompressed ECC key.
Thanks for the help

Erwin

What makes you think that? OpenSSL 0.9.8 only supports SHA1 with ECDSA
Version of ECDSA available in openssl 1.0.0d supports only SHA1.
(maybe there are patches, which adds other hash functions, but
default build on win32 supports only sha1).
ECDH and ECDSA are not guaranteed to use the same curve. At least
with s_server curve for ECDSA is specified in certifica
Hello,
The "tls-unique" channel binding is necessary to implement the
SCRAM-SHA-1-PLUS authentication mechanisms (see RFC 5802, RFC 5929).
We have a pending patch for Python's ssl binding to compute that
piece of information (*), and I would like to know if there's some
example code somewhere so

Hi Mayur,
You can create a file where you may concatenate all your trusted
certificates in PEM format and use that file for verification.
Another way is to store your trusted certificates in PEM format in
filesystem and create a folder from where you create symbolic links to every
certificate. The
Hi ,
I am using openssl for signature verification of the files in my
application.
For supporting multiple root certificates , Is there a db or storage
area[file] which openssl searches
while finding the root of the passed input certificates ?
I am using X509_Verify_cert api of openssl to v
