"""Import a DSA key (public or private).
:Parameters:
extern_key : (byte) string
The DSA key to import.
An DSA *public* key can be in any of the following formats:
- X.509 certificate (binary or PEM format)
- X.509 ``subjectPublicKeyInfo`` (binary or PEM)
- OpenSSH (one line of text, see `RFC4253`_)
A DSA *private* key can be in any of the following formats:
- `PKCS#8`_ ``PrivateKeyInfo`` or ``EncryptedPrivateKeyInfo``
DER SEQUENCE (binary or PEM encoding)
- OpenSSL/OpenSSH (binary or PEM)
For details about the PEM encoding, see `RFC1421`_/`RFC1423`_.
The private key may be encrypted by means of a certain pass phrase
either at the PEM level or at the PKCS#8 level.
passphrase : string
In case of an encrypted private key, this is the pass phrase
from which the decryption key is derived.
verify_x509_cert : bool
When importing the public key from an X.509 certificate, whether
the certificate should be validated. **Since verification is not
yet supported, this value must always be set to False**.
This value is ignored if an X.509 certificate is not passed.
:Return: A DSA key object (`DsaKey`).
:Raise ValueError:
When the given key cannot be parsed (possibly because
the pass phrase is wrong).
