def generate_key(bits):
"""Generate a paramiko RSAKey"""
# NOTE(dims): pycryptodome has changed the signature of the RSA.generate
# call. specifically progress_func has been dropped. paramiko still uses
# pycrypto. However some projects like latest pysaml2 have switched from
# pycrypto to pycryptodome as pycrypto seems to have been abandoned.
# paramiko project has started transition to pycryptodome as well but
# there is no release yet with that support. So at the moment depending on
# which version of pysaml2 is installed, Nova is likely to break. So we
# call "RSA.generate(bits)" which works on both pycrypto and pycryptodome
# and then wrap it into a paramiko.RSAKey
rsa = RSA.generate(bits)
