/** Tests for the UncachedKeyring.merge method.
*
* This is another complex, crypto-related method. It merges information from one keyring into
* another, keeping information from the base (ie, called object) keyring in case of conflicts.
* The types of keys may be Public or Secret and can be mixed, For mixed types the result type
* will be the same as the base keyring.
*
* Test cases:
* - Merging keyrings with different masterKeyIds should fail
* - Merging a key with itself should be a no-operation
* - Merging a key with an extra revocation certificate, it should have that certificate
* - Merging a key with an extra user id, it should have that extra user id and its certificates
* - Merging a key with an extra user id certificate, it should have that certificate
* - Merging a key with an extra subkey, it should have that subkey
* - Merging a key with an extra subkey certificate, it should have that certificate
* - All of the above operations should work regardless of the key types. This means in particular
* that for new subkeys, an equivalent subkey of the proper type must be generated.
* - In case of two secret keys with the same id but different S2K, the key of the base keyring
* should be preferred (TODO or should it?)
*
* Note that the merge operation does not care about certificate validity, a bad certificate or
* packet will be copied regardless. Filtering out bad packets is done with canonicalization.
*

Original README
===============
This is an OpenPGP library inspired by my work on OpenPGP libraries in
Ruby <https://github.com/singpolyma/openpgp>,
PHP <http://github.com/singpolyma/openpgp-php>,
and Python <https://github.com/singpolyma/OpenPGP-Python>.
It defines types to represent OpenPGP messages as a series of packets
and then defines instances of Data.Binary for each to facilitate
encoding/decoding.
For performing cryptography, see
<http://hackage.haskell.org/package/openpgp-crypto-api> or
<http://hackage.haskell.org/package/openpgp-Crypto>
For dealing with ASCII armor, see
<http://hackage.haskell.org/package/openpgp-asciiarmor>
It is intended that you use qualified imports with this library.
> import qualified Data.OpenPGP as OpenPGP
