securing the repo where:
A: deb repo
B: rpm repo
C: main repo (rpm and deb)

A:
create keys:gpg --gen-key
NAME=uid without . get it using gpg --list-keys
modify $REPO_HOME/conf/distributions so it contains following line:
SignWith=NAME
sign (and add to the repository) the package: reprepro --ask-passphrase -A ARCH -Vb $REPO_HOME CODENAME some-package.deb
ARCH=i386, all, amd64..
CODENAME=check conf/distributions for this

export public key: gpg --export -a 'NAME' > export-file-of-public-key
..and secret key: gpg --export-secret-keys > export-file-of-secret-key

copy the exported files to B: scp...........

add following line to conf/distribution:
Origin: Sasa C
Label: some-label
Suite: suiteX
Codename: testing
Architectures: i386 amd64 all source
Components: main
Description: some desc
SignWith: 'NAME'

add/sign to the repo using: reprepro --ask-passphrase -A all -Vb . includedeb suiteX some-package.deb


B:
import public key: gpg --import export-file-of-public-key
import secret key: gpg --allow-secret-key-import --import export-file-of-secret-key

create ~/.rpmmacros and add this lines:
%_signature gpg
%_gpg_name NAME # same as one used to export public key on A

import public key to RPM DB: rpm --import export-file-of-public-key
sign the rpm package: rpm --addsign some-package.rpm

some useful commands:
list: rpm -q gpg-pubkey --qf '%{name}-%{version}-%{release} --> %{summary}\n'
delete: rpm -e gpg-pubkey-22ed62d1-48460969
check: rpm --checksig some-package.rpm
