Hello Florian,
change in size of openssl package is 128 kB (quite significant).
1428 kB
test_no_ecdsa/build_dir/target-mips_r2_uClibc-0.9.33/openssl-1.0.0g/ipkg-ar71xx/
1556 kB
test_ecdsa/build_dir/target-mips_r2_uClibc-0.9.33/openssl-1.0.0g/ipkg-ar71xx/
enabled ECDSA make also openssh bigger by 36 kB
1072 kB
test_no_ecdsa/build_dir/target-mips_r2_uClibc-0.9.33/openssh-5.9p1/ipkg-ar71xx/
1108 kB
test_ecdsa/build_dir/target-mips_r2_uClibc-0.9.33/openssh-5.9p1/ipkg-ar71xx/
- in mine build only these two packages get affected (in size) by enabling
ECDSA,
the rest of packages remains the same in size, even syslog-ng3 which depends on
openssl
- openssl got only options to turn off elliptic curves
('no-ec','no-ecdh','no-ecdsa'),
by default openssl builds with 'ec' enabled
What about configurable option in openssl package in configuration menu to
enable elliptic curves (by default disabled) ?
