Package zeroinstall :: Package injector :: Module gpg

Module gpg

Python interface to GnuPG.

This module is used to invoke GnuPG to check the digital signatures on interfaces.

Classes
	Signature Abstract base class for signature check results.
	ValidSig A valid signature check result.
	BadSig A bad signature (doesn't match the message).
	ErrSig Error while checking a signature.
	Key A GPG key.

Functions

{str: Key}

load_keys(fingerprints)
Load a set of keys at once.

source code

Key

load_key(fingerprint)
Query gpg for information about this key.

source code

import_key(stream)
Run gpg --import with this stream as stdin. source code

check_stream(stream)
Pass stream through gpg --decrypt to get the data, the error text, and a list of signatures (good or bad).

source code

Function Details

load_keys(fingerprints)

source code

Load a set of keys at once. This is much more efficient than making individual calls to load_key.

Returns: {str: Key}: a list of loaded keys, indexed by fingerprint

Since: 0.27

load_key(fingerprint)

source code

Query gpg for information about this key.

Returns: Key: a new key

Since: 0.27

check_stream(stream)

source code

Pass stream through gpg --decrypt to get the data, the error text, and a list of signatures (good or bad). If stream starts with "<?xml " then get the signature from a comment at the end instead (and the returned data is the original stream). stream must be seekable.

Returns:: (data_stream, [Signatures])

Note: Stream returned may or may not be the one passed in. Be careful!
