.PP 
.SH "NAME"
FBB::CryptBuf \- std::streambuf derived base class for DecryptBuf
and EncryptBuf
.PP 
.SH "SYNOPSIS"
\fB#include <bobcat/cryptbuf>\fP
.br 
Linking option: \fI\-lbobcat \-lcrypto\fP
.PP 
.SH "DESCRIPTION"
This class is deprecated and will be removed from Bobcat in a future
release\&. It inherits from \fIFBB::EoiBuf\fP\&. Classes using \fICryptBuf\fP may use
\fIEoiBuf\fP instead\&. \fICryptBuf\(cq\&s\fP member \fIEVP_CIPHER const *md()\fP can be
implemented as follows:
.nf 

    #include <openssl/evp\&.h>

    EVP_CIPHER const *md(char const *cipherName)
    {
        return EVP_CIPHER_fetch(0, cipherName, 0);
    }
        
.fi 

.PP 
.SH "NAMESPACE"
\fBFBB\fP
.br 
All constructors, members, operators and manipulators, mentioned in this
man\-page, are defined in the namespace \fBFBB\fP\&.
.PP 
.SH "INHERITS FROM"
\fIEoiBuf\fP (and thus from: \fIstd::streambuf\fP)
.PP 
.SH "PROTECTED CONSTRUCTOR"

.PP 
Analogously to \fIstd::streambuf\fP only a protected constructor is
available\&.
.PP 
.IP o 
\fBCryptBuf(char const *type, size_t bufSize)\fP:
.br 
The type is a null\-terminated byte string specifying the de/encryption
method\&. E\&.g\&., \fIaes\-128\-cbc\fP\&. For an overview see the
\fBencryptbuf\fP(3bobcat) man\-page\&. The \fIbufSize\fP parameter defines
the initial size of the internally used buffer (defined by
\fIEoiBuf\fP)\&.

.PP 
Copy and move constructors (and assignment operators) are not available\&.
.PP 
.SH "PROTECTED MEMBER FUNCTION"

.PP 
All members of \fIstd:streambuf\fP and \fIEoiBuf\fP are available, as
\fBFBB::CryptBuf\fP inherits from these classes\&.
.PP 
.IP o 
\fBEVP_CIPHER const *md() const\fP:
.br 
A pointer to the cipher information is returned\&.

.PP 
.SH "FILES"
\fIbobcat/cryptbuf\fP \- defines the class interface

.SH "SEE ALSO"

.SH "BUGS"
This class is deprecated and will be removed from Bobcat in a future
release\&.
