+\section{Introduction}
+
+\emph{Note that this is a draft, and almost certainly does not comply with what
+FIPS 140-2 wants (also it's incomplete). In any case, there is no way for me to
+afford paying the validation lab, so this is all theoretical.}
+
+\emph{I would welcome comments from people who are familiar with the FIPS 140
+process. I am currently basing this off a few dozen other security policies and
+the FIPS itself.}
+
+\subsection{Purpose}
+
+This document is a security policy for the Botan C++ crypto library for use in
+a FIPS 140-2 Level 1 validation process. It describes how to configure and use
+the library to comply with the requirements of FIPS 140-2.
+
+This document is non-proprietary, and may be freely reproduced and distributed
+in unmodified form.
+
+\subsection{Product Description}
+
+The Botan C++ crypto library (hereafter ``Botan'' or ``the library'') is an
+open source C++ class library providing a general-purpose interface to a wide
+variety of cryptographic algorithms and formats (such as X.509v3 and PKCS
+\#10). It runs on most Win32 and POSIX-like systems, including Windows
+NT/2000/XP, MacOS X, Linux, Solaris, FreeBSD, and QNX. However, only versions
+running on \emph{(goal:)} Windows XP, Linux, and Solaris have been validated by
+FIPS 140-2 at this time.
+
+\subsection{Algorithms}
+
+The library contains the following FIPS Approved algorithms: RSA, DSA, DES,
+TripleDES, Skipjack, AES, SHA-1, HMAC, the X9.19 DES MAC, and the FIPS 186-2
+SHA-1 RNG. Other (non-Approved) algorithms, such as MD5 and Diffie-Hellman, are
+also included.
+
+\section{Initialization}
+
+Certain tests are only performed if the flag ``fips140'' is passed as part of
+the initialization process to the library (the argument to
+\type{LibraryInitializer} or \function{Init::initialize}). Known answer tests
+and key generation self-checks for RSA and DSA are always performed, regardless
+of this setting. This flag must be passed by any application which desires
+using the FIPS 140 mode of operation.
+
+\section{Roles and Services}
+
+Botan supports two roles, the User and the Crypto Officer. Authentication is
+not performed by the module; all authentication is implicitly done by the
+operating system.
+
+\subsection{User Role}
+
+The user has the ability to access the services of the module. This role is
+implicitly selected whenever the module's services are accessed.
+
+\subsection{Crypto Officer Role}
+
+The crypto officer has all of the powers of the user, and in addition has the
+power to install and uninstall the module and to configure the operating
+system. This role is implicitly selected whenever these actions are performed.
+
+\section{Key Management}
+
+\subsection{Key Import/Export}
+
+Symmetric keys can be imported and exported in either unencrypted, encrypted,
+or split-knowledge forms, as the application desires. Private keys for
+asymmetric algorithms can be imported and exported as either encrypted or
+unencrypted PKCS \#8 structures. The library natively supports PKCS \#5
+encryption with TripleDES for encrypting private keys.
+
+\subsection{Key Storage}
+
+In no case does the library itself import or export keys from/to an external
+storage device; all such operations are done explicitly by the application. It
+is the responsibly of the operator to ensure than any such operations comply
+with the requirements of FIPS 140-2 Level 1.
+
+\subsection{Key Generation}
+
+Keys for symmetric algorithms (such as DES, AES, and HMAC) are generated by an
+Approved RNG, by generating a random byte string of the appropriate size, and
+using it as a key.
+
+DSA keys are generated as specified in FIPS 186-2 (or not?). RSA keys are
+generated as specified in ANSI X9.31 (\emph{I think...}). Diffie-Hellman keys
+are generated in a manner compatible with ANSI X9.42. All newly created DSA and
+RSA keys are checked with a pairwise consistency test before being returned to
+the caller. A pairwise consistency check can be performed on any RSA, DSA, or
+Diffie-Hellman key by calling the \function{check\_key} member function with
+an argument of \type{true}.
+
+\subsection{Key Establishment}
+
+Botan supports using RSA or Diffie-Hellman to establish keys. RSA can be used
+with PKCS \#1 v1.5 or OAEP padding. None of these methods are FIPS Approved,
+but Annex D of FIPS 140-2 allows for their use until such time as a FIPS
+Approved asymmetric key establishment method is established.
+
+\subsection{Key Protection / Zeroization}
+
+Keys are protected against external access by the operating system's memory and
+process protection mechanisms. If the library is used by multiple processes at
+once, the OS virtual memory mechanisms ensure that each version will have it's
+own data space (and thus, keys are not shared among multiple processes).
+
+All keys and other sensitive materials are zeroed in memory before being
+released to the system.
+
+On Windows systems the \function{VirtualLock} system call is used to notify the
+operating system that the memory containing potentially sensitive keying
+material is not swapped to disk, preventing an attacker from applying disk
+forenistics techniques to recovery data.
+
+On Unix systems, Botan allocates memory from file-backed memory mappings, which
+are thoroughly erased when the memory is freed.
