\ingroup HighLevel_KeyringRead
\brief Reads a keyring from memory
\param keyring Pointer to existing ops_keyring_t struct
\param armour ops_true if file is armoured; else ops_false
\param mem Pointer to a ops_memory_t struct containing keyring to be read
\return ops true if OK; ops_false on error
\note Keyring struct must already exist.
\note Can be used with either a public or secret keyring.
\note You must call ops_keyring_free() after usage to free alloc-ed memory.
\note If you call this twice on the same keyring struct, without calling
ops_keyring_free() between these calls, you will introduce a memory leak.
