* gpgkeys_curl.c, gpgkeys_hkp.c, gpgkeys_ldap.c, curl-shim.c:
* curl-shim.h, ksutil.c, ksutil.h: Add special license exception
for OpenSSL. This helps to avoid license conflicts if OpenLDAP or
cURL is linked against OpenSSL and we would thus indirectly link
to OpenSSL. This is considered a bug fix and forgives all
possible violations, pertaining to this issue, possibly occured in
the past.
* Makefile.am (gpg2keys_ldap_LDADD): For license reasons do not
link against common_libs.
(gpg2keys_curl_LDADD, gpg2keys_hkp_LDADD): Ditto.
* ksutil.c (ks_hextobyte, ks_toupper, ks_strcasecmp): New.
Identical to the ascii_foo versions from jnlib.
* gpgkeys_ldap.c: Include assert.h.
(main): Replace BUG by assert.
(build_attrs): Use ks_hextobyte and ks_strcasecmp.
* gpgkeys_finger.c (get_key): Resolved signed/unisgned char
mismatch.
2006-09-19 Werner Koch <wk@g10code.com>
