Description of problem:
In par. 4.2.1 it says to use key type 2 (DSA and Elgamal) for the key. This results in a unverifyable V4 signature:
error: skipping package rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm with unverifiable V4 signature

Using key type 1 (RSA and RSA) gives a better result:
[root@node1 ~]# rpm --checksig -v rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm
rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm:
    Header V4 RSA/SHA1 Signature, key ID 6dc06f30: OK
    Header SHA1 digest: OK (0568898722e26e5df2c25fe239b72ac98667a66d)
    V4 RSA/SHA1 Signature, key ID 6dc06f30: OK
    MD5 digest: OK (05ef84979d583bd5c7b81e8dede72433)


Version-Release number of selected component (if applicable):
RHEL 6.5 x68_64

How reproducible:
See steps v

Steps to Reproduce:
1. Follow par 4.2.1 and 4.2.2 to the letter on a RHEL 6.5 box
2.
3.

Actual results:
error: skipping package rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm with unverifiable V4 signature

Expected results:
rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm:
    Header V4 RSA/SHA1 Signature, key ID 6dc06f30: OK
    Header SHA1 digest: OK (0568898722e26e5df2c25fe239b72ac98667a66d)
    V4 RSA/SHA1 Signature, key ID 6dc06f30: OK
    MD5 digest: OK (05ef84979d583bd5c7b81e8dede72433)
