%description
A comprehensive, modular and portable cryptographic toolkit that
provides developers with a vast array of well known published block
ciphers, one-way hash functions, chaining modes, pseudo-random number
generators, public key cryptography and a plethora of other routines.

Designed from the ground up to be very simple to use. It has a modular
and standard API that allows new ciphers, hashes and PRNGs to be added
or removed without change to the overall end application. It features
easy to use functions and a complete user manual which has many source
snippet examples. 

The library is available as 32-bit and 64-bit.


%package        devel
Summary:        Development files for %{name}
Group:          Development/Libraries
Requires:       %{name} = %{version}-%{release}

%description    devel
The %{name}-devel package contains libraries and header files for
developing applications that use %{name}.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc_r -q64" or "gcc -maix64".
