[bug#50029] [PATCH] adb, use openssl 1.1

[-- Attachment #1.1: Type: text/plain, Size: 154 bytes --]

Hello maintainers,

As promised in [bug#49859] I was able to assemble a patch for adb to use
openssl 1.1 instead of the old and unsopported openssl 1.0.

Subject: [PATCH] gnu: adb: Make compatible with openssl 1.1

OpenSSL version 1.1 brought some API changes which broke the build here, fix
that by accessing rsa->n (and e) directly, using RSA_get0_key instead.

As described in the patch, I got the patch from Debian [1] and
fortunately it applies as-is! (I'm not able to asses the code but I'm
pretty sure Debian maintener did it for me).

I was able to build and install the package and tested it by connecting
to my Android phone with adb via wi-fi: is this a viable test to check
if the patch is OK?

Happy hacking! Gio'

I cleaned up the commit message and renamed the patch to
