| The dh_params Resource |
dh_params
Use the dh_params InSpec audit resource to test Diffie-Hellman (DH) parameters.
Syntax
A dh_params resource block declares a parameter file to be tested.
describe dh_params('/path/to/file.dh_pem') do
it { should be_dh_params }
it { should be_valid }
its('generator') { should eq 2 }
its('modulus') { should eq '00:91:a0:15:89:e5:bc:38:93:12:02:fc:...' }
its('prime_length') { should eq 2048 }
its('pem') { should eq '-----BEGIN DH PARAMETERS...' }
its('text') { should eq 'PKCS#3 DH Parameters: (2048 bit)...' }
end
Supported Properties
dh_params?
Verify whether file contains DH parameters:
describe dh_params('/path/to/file.dh_pem') do
it { should be_dh_params }
end
valid?
Verify whether DH parameters are valid:
describe dh_params('/path/to/file.dh_pem') do
it { should be_valid }
end
generator (Integer)
Verify generator used for the Diffie-Hellman operation:
describe dh_params('/path/to/file.dh_pem') do
its('generator') { should eq 2 }
end
modulus (String)
Verify prime modulus used for the Diffie-Hellman operation:
describe dh_params('/path/to/file.dh_pem') do
its('modulus') { should eq '00:91:a0:15:89:e5:bc:38:93:12:02:fc:...' }
end
Example using multi-line string:
describe dh_params('/path/to/file.dh_pem') do
its('modulus') do
# regex removes all whitespace
should eq <<-EOF.gsub(/[[:space:]]+/, '')

EOF
end
end
prime_length (Integer)
Verify length of prime modulus used for the Diffie-Hellman operation:
describe dh_params('/path/to/file.dh_pem') do
its('prime_length') { should eq 2048 }
end
pem (String)
Verify pem output of DH parameters:
describe dh_params('/path/to/file.dh_pem') do
its('pem') { should eq '-----BEGIN DH PARAMETERS...' }
end
Example using multi-line string:
its('pem') do
# regex removes all leading spaces
should eq <<-EOF.gsub(/^[[:blank:]]+/, '')
