The file format described by this document provides no mechanism
to verify the integrity or otherwise detect tampering of the
data stored in such files. It is the responsibility of the parties
that create or exchange files written in this format to ensure that
appropriate access controls are applied to such files, and that
the files, if transfered, are exchanged over a trusted channel.
The data encoded using this file format is sensitive.
"sensitive" in what sense?
Implementors are cautioned to verify the correctness of the
encoding/decoding routines used to save and read files in this
format. A malfunctioning decoder used to read a public-key file
will most likely produce unsound data of unknown cryptographic
properties that in the worst case could be vulnerable various
forms of cryptographic attack.
