* contrib/hbssl/hbssl.h
* contrib/hbssl/evppkey.c
* contrib/hbssl/rsa.c
* reenabled hb_RSA_par_remove() for old OpenSSL() versions (<=0.9.6) which
do not support RSA_up_ref()
* contrib/hbssl/ssl.c
! use
x509 = X509_dup( x509 );
X509_check_purpose( x509, -1, 0 );
instead of
X509_up_ref( x509 );
in OpenSSL versions prior 0x10100000L - they do not support X509_up_ref()
* contrib/hbssl/x509.c
* check passed parameters more strictly
* return NIL when X509 certificate cannot be allocated/accessed
