<p>
<h2>NAME</h2>FBB::ISymCryptStream - Istream performing symmetric encryption
<p>
<h2>SYNOPSIS</h2>
    <strong>#include &lt;bobcat/isymcryptstream&gt;</strong><br>
    Linking option: <em>-lbobcat -lcrypto</em> 
<p>
<h2>DESCRIPTION</h2>
    <strong>FBB::ISymCryptStream</strong> objects may be used to encrypt or decrypt
information that is available on a separate <em>std::istream</em>.
<p>
The <em>class ISymCryptStream</em> is a class template, using a
<em>FBB::CryptType</em> template non-type parameter. Objects of the class 
<em>FBB::ISymCryptStream&lt;FBB::ENCRYPT&gt;</em> encrypt the information they receive,
objects of the class <em>FBB::ISymCryptStream&lt;FBB::DECRYPT&gt;</em> decrypt the
information they receive.
<p>
All symmetric encryption methods defined by the OpenSSL library that can
be selected by name may be used in combination with <em>EncryptBuf</em> objects. To
select a particular encryption method an identifier is passed to the
constructor. E.g., <em>"aes-128-cbc"</em> indicating the AES (Rijndael) method,
using 128 bit sized keys and blocks using `cbc' mode (see below for an
explanation).
<p>
Refer to the <strong>isymcryptstreambuf</strong>(3bobcat) man-page for a descryption of
available encryption methods.
<p>
<h2>NAMESPACE</h2>
    <strong>FBB</strong><br>
    All constructors, members, operators and manipulators, mentioned in this
man-page, are defined in the namespace <strong>FBB</strong>.
<p>
<h2>INHERITS FROM</h2>
    <strong>FBB::ISymCryptStreambuf</strong> (private), <br>
    <strong>std::istream</strong> 
<p>
<h2>CONSTRUCTOR</h2>
    <ul>
    <li> <strong>ISymCryptStream&lt;CryptType&gt;(
                   std::istream &amp;in,        char const *type,
                   std::string const &amp;key,  std::string const &amp;iv,
                   size_t bufSize = 100,    size_t filterBufSize = 1000, 
                   ENGINE *engine = 0)</strong>:<br>
        This constructor initializes a <em>std::istream</em> providing it with an
<em>FBB::ISymCryptStreambuf</em> stream buffer. The <em>ISymCryptStreambuf</em>'s
constructor receives all arguments that are passed to this constructor.
<p>
- <em>ISymCryptStream&lt;ENCRYPT&gt;</em> objects perform encryption;<br>
        <em>ISymCryptStream&lt;DECRYPT&gt;</em> objects perform decryption;<br>
    - <em>ISymCryptStream&lt;CryptType&gt;</em> objects obtain the bytes to encrypt
or decrypt from <em>std::istream &amp;in</em>;<br>
    - The encryption method to use is specified by the <em>type</em>
parameter. E.g., <em>"bf-cbc"</em> selects the Blowfish Cipher Block Chaining
method;<br>
    - The symmetric key to use is specified by the <em>key</em> parameter;<br>
    - The initialization vector is specified by the <em>iv</em> parameter;<br>
    - The <em>FBB::ISymCryptStreambuf</em> internally used buffer will contain
<em>bufSize</em> characters. The default value is the smallest value that is
used. When a smaller <em>bufSize</em> value is specified, the default value is
used;<br>
    - The internally used <em>IFilterStreambuf</em> is initialized with a buffer of
size <em>filterBufSize</em>, using a lower bound of 100;<br>
    - The parameter <em>ENGINE</em> can be used to specify a hardware
accelleration engine, as supported by the used encryption/decryption
method. Its default argument value indicates that no hardware accelleration is
available.
    </ul>
<p>
<h2>INHERITED MEMBERS</h2>
<p>
Since the class uses public derivation from <strong>std::istream</strong>, all members
of this class can be used.
<p>
<h2>EXAMPLE</h2>
    <pre>
#include "../isymcryptstream"

#include &lt;iostream&gt;

using namespace std;
using namespace FBB;

int main()
{
    ISymCryptStream&lt;ENCRYPT&gt; encryptor(cin, "bf-cbc",
                                    "1234567890", "1234567890");

    ISymCryptStream&lt;DECRYPT&gt; decryptor(encryptor, "bf-cbc",
                                    "1234567890", "1234567890");

    cout &lt;&lt; decryptor.rdbuf();
}
</pre>

<h2>BUGS</h2>
<p>
Sep/Oct 2013: due to a change in library handling by the linker
(cf. <a href="http://fedoraproject.org/wiki/UnderstandingDSOLinkChange">http://fedoraproject.org/wiki/UnderstandingDSOLinkChange</a> and
<a href="https://wiki.debian.org/ToolChain/DSOLinking">https://wiki.debian.org/ToolChain/DSOLinking</a>) libraries that are
indirectly required are no longer automatically linked to your program. With
<strong>BigInt</strong> this is <em>libcrypto</em>, which requires programs to link to both
<em>bobcat</em> and <em>crypto</em>.
