Re: [Buildroot] [EXT] Re: [PATCH 1/1] package/opkg: enable openssl signature

[Andrei FOMITCHEV HERVIEU <andrei.fomitchevhervieu@getinge.com>]

Hello Thomas,

Thank you for the point. Maybe you remember, I (still) use the version 2021.02 of buildroot and this version integrates the version 0.4.2 of OPKG. The quoted comment in OPKG sources was introduced in v0.4.5 and the reason is "relatively unused feature" of OpenSSL signatures (https://groups.google.com/g/opkg-devel/c/drqw5_HuXuU).
So I agree, the OPKG project plans make my patch to buildroot useless

Best regards

Nice to see you here, thanks for the contribution!

However, are you sure it makes sense to support this and use this?
Indeed, opkg has deprecated the usage of openssl for signature. From
opkg's configure.ac:

AC_MSG_WARN(OpenSSL signature-checking support is depracted and will be \
removed in future releases. Consider using GPGME (--enable-gpg) instead.)

So, it is really sensible to support this?

Thomas
