Could there be an older version of openssl in your search path? The EVP_PKEY_CTX_* routines were new in 1.0.0. If you are finding a version older than that, they will be missing. For Windows note that the DLL search rules have changed several times over the last year or so as Microsoft puts out more and more security patches for "DLL planting" attacks. > Instead this three lines, with the next two lines the App can > also load the dll and it works: > > 4.

All EVP_* or only all EVP_PKEY_CTX_* ? Most other parts of EVP_ are quite a bit older, although there have been minor changes. > Anyway, as you said the EVC functions where recent development effort > foccus, I think this may be some error in openssl lib.

Are you installing it in the system directory(s), or using in your own dir(s)? If the latter, is there any openssl in the system dir(s)? The specific system directory(s) depend on your OS, and possibly build options. You imply you are doing at least Windows plus some Unix, which are different; if you do more than one Unix, those may also be different. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
