操作

Clean up "generic" intro pod files. 

Files like dh.pod, etc., mostly duplicated the API-specific pod files.
Removed the duplicated content; that often mean the whole file could
be removed.  Some of the content about internals got moved into README
files in the source tree.  Some content (e.g., err.pod) got moved
into other pod pages.

Annotate generic pages, remove dup NAME

Adding new libraries
--------------------
When adding a new sub-library to OpenSSL, assign it a library number
ERR_LIB_XXX, define a macro XXXerr() (both in err.h), add its
name to ERR_str_libraries[] (in crypto/err/err.c), and add
ERR_load_XXX_strings() to the ERR_load_crypto_strings() function
(in crypto/err/err_all.c). Finally, add an entry:
L XXX xxx.h xxx_err.c
to crypto/err/openssl.ec, and add xxx_err.c to the Makefile.
Running make errors will then generate a file xxx_err.c, and
add all error codes used in the library to xxx.h.
Additionally the library include file must have a certain form.
Typically it will initially look like this:
#ifndef HEADER_XXX_H
#define HEADER_XXX_H
#ifdef __cplusplus
extern "C" {
#endif
/* Include files */
#include <openssl/bio.h>
#include <openssl/x509.h>
/* Macros, structures and function prototypes */
/* BEGIN ERROR CODES */
The BEGIN ERROR CODES sequence is used by the error code
generation script as the point to place new error codes, any text
after this point will be overwritten when make errors is run.
The closing #endif etc will be automatically added by the script.
The generated C error code file xxx_err.c will load the header
files stdio.h, openssl/err.h and openssl/xxx.h so the
header file must load any additional header files containing any
definitions it uses.

=head2 Reporting errors
Each sub-library has a specific macro XXXerr() that is used to report
errors. Its first argument is a function code B<XXX_F_...>, the second
argument is a reason code B<XXX_R_...>. Function codes are derived
from the function names; reason codes consist of textual error
descriptions. For example, the function ssl3_read_bytes() reports a
"handshake failure" as follows:
SSLerr(SSL_F_SSL3_READ_BYTES, SSL_R_SSL_HANDSHAKE_FAILURE);
Function and reason codes should consist of upper case characters,
numbers and underscores only. The error file generation script translates
function codes into function names by looking in the header files
for an appropriate function name, if none is found it just uses
the capitalized form such as "SSL3_READ_BYTES" in the above example.
The trailing section of a reason code (after the "_R_") is translated
into lower case and underscores changed to spaces.
When you are using new function or reason codes, run B<make errors>.
The necessary B<#define>s will then automatically be added to the
sub-library's header file.
Although a library will normally report errors using its own specific
XXXerr macro, another library's macro can be used. This is normally
only done when a library wants to include ASN1 code which must use
the ASN1err() macro.

=head1 DESCRIPTION
This library performs arithmetic operations on integers of arbitrary
size. It was written for use in public key cryptography, such as RSA
and Diffie-Hellman.
It uses dynamic memory allocation for storing its data structures.
That means that there is no limit on the size of the numbers
manipulated by these functions, but return values must always be
checked in case a memory allocation error has occurred.
The basic object in this library is a B<BIGNUM>. It is used to hold a
single large integer. This type should be considered opaque and fields
should not be modified or accessed directly.
The creation of B<BIGNUM> objects is described in L<BN_new(3)>;
L<BN_add(3)> describes most of the arithmetic operations.
Comparison is described in L<BN_cmp(3)>; L<BN_zero(3)>
describes certain assignments, L<BN_rand(3)> the generation of
random numbers, L<BN_generate_prime(3)> deals with prime
numbers and L<BN_set_bit(3)> with bit operations. The conversion
of B<BIGNUM>s to external formats is described in L<BN_bn2bin(3)>.

=head1 DESCRIPTION
These functions implement the Diffie-Hellman key agreement protocol.
The generation of shared DH parameters is described in
L<DH_generate_parameters(3)>; L<DH_generate_key(3)> describes how
to perform a key agreement.
The B<DH> structure consists of several BIGNUM components. The prime B<p>, the
generate B<g>, the Private key B<priv_key> and the public key B<pub_key>.
Optionally there may also be an additional parameter B<q>.
Note that DH keys may use non-standard B<DH_METHOD> implementations,
either directly or by the use of B<ENGINE> modules. In some cases (eg. an
ENGINE providing support for hardware-embedded keys), these BIGNUM values
will not be used by the implementation or may be used for alternative data
storage.

=head1 DESCRIPTION
These functions implement the Digital Signature Algorithm (DSA). The
generation of shared DSA parameters is described in
L<DSA_generate_parameters(3)>;
L<DSA_generate_key(3)> describes how to
generate a signature key. Signature generation and verification are
described in L<DSA_sign(3)>.
The B<DSA> structure consists of several BIGNUM components.
struct
{
BIGNUM *p; // prime number (public)
BIGNUM *q; // 160-bit subprime, q | p-1 (public)
BIGNUM *g; // generator of subgroup (public)
BIGNUM *priv_key; // private key x
BIGNUM *pub_key; // public key y = g^x
// ...
}
DSA;
In public keys, B<priv_key> is NULL.
Note that DSA keys may use non-standard B<DSA_METHOD> implementations,
either directly or by the use of B<ENGINE> modules. In some cases (eg. an
ENGINE providing support for hardware-embedded keys), these BIGNUM values
will not be used by the implementation or may be used for alternative data
storage. For this reason, applications should generally avoid using DSA
structure elements directly and instead use API functions to query or
modify keys.

=head1 DESCRIPTION
This library provides an extensive set of functions for performing operations on elliptic curves over finite fields.
In general an elliptic curve is one with an equation of the form:
y^2 = x^3 + ax + b
An B<EC_GROUP> structure is used to represent the definition of an elliptic curve. Points on a curve are stored using an
B<EC_POINT> structure. An B<EC_KEY> is used to hold a private/public key pair, where a private key is simply a BIGNUM and a
public key is a point on a curve (represented by an B<EC_POINT>).
The library contains a number of alternative implementations of the different functions. Each implementation is optimised
for different scenarios. No matter which implementation is being used, the interface remains the same. The library
handles calling the correct implementation when an interface function is invoked. An implementation is represented by
an B<EC_METHOD> structure.
The creation and destruction of B<EC_GROUP> objects is described in L<EC_GROUP_new(3)>. Functions for
manipulating B<EC_GROUP> objects are described in L<EC_GROUP_copy(3)>.
Functions for creating, destroying and manipulating B<EC_POINT> objects are explained in L<EC_POINT_new(3)>,
whilst functions for performing mathematical operations and tests on B<EC_POINTs> are covered in L<EC_POINT_add(3)>.
For working with private and public keys refer to L<EC_KEY_new(3)>. Implementations are covered in
L<EC_GFp_simple_method(3)>.
For information on encoding and decoding curve parameters to and from ASN1 see L<d2i_ECPKParameters(3)>.

=head1 DESCRIPTION
When a call to the OpenSSL library fails, this is usually signaled
by the return value, and an error code is stored in an error queue
associated with the current thread. The B<err> library provides
functions to obtain these error codes and textual error messages.
The L<ERR_get_error(3)> manpage describes how to
access error codes.
Error codes contain information about where the error occurred, and
what went wrong. L<ERR_GET_LIB(3)> describes how to
extract this information. A method to obtain human-readable error
messages is described in L<ERR_error_string(3)>.
L<ERR_clear_error(3)> can be used to clear the
error queue.
=head1 ADDING NEW ERROR CODES TO OPENSSL
See L<ERR_put_error(3)> if you want to record error codes in the
OpenSSL error system from within your application.
The remainder of this section is of interest only if you want to add
new error codes to OpenSSL or add error codes from external libraries.

Each sub-library has a specific macro XXXerr() that is used to report
errors. Its first argument is a function code B<XXX_F_...>, the second
argument is a reason code B<XXX_R_...>. Function codes are derived
from the function names; reason codes consist of textual error
descriptions. For example, the function ssl3_read_bytes() reports a
"handshake failure" as follows:
SSLerr(SSL_F_SSL3_READ_BYTES, SSL_R_SSL_HANDSHAKE_FAILURE);
Function and reason codes should consist of upper case characters,
numbers and underscores only. The error file generation script translates
function codes into function names by looking in the header files
for an appropriate function name, if none is found it just uses
the capitalized form such as "SSL3_READ_BYTES" in the above example.
The trailing section of a reason code (after the "_R_") is translated
into lower case and underscores changed to spaces.
When you are using new function or reason codes, run B<make errors>.
The necessary B<#define>s will then automatically be added to the
sub-library's header file.
Although a library will normally report errors using its own specific
XXXerr macro, another library's macro can be used. This is normally
only done when a library wants to include ASN1 code which must use
the ASN1err() macro.
=head2 Adding new libraries
When adding a new sub-library to OpenSSL, assign it a library number
B<ERR_LIB_XXX>, define a macro XXXerr() (both in B<err.h>), add its
name to B<ERR_str_libraries[]> (in B<crypto/err/err.c>), and add
C<ERR_load_XXX_strings()> to the ERR_load_crypto_strings() function
(in B<crypto/err/err_all.c>). Finally, add an entry
L XXX xxx.h xxx_err.c
to B<crypto/err/openssl.ec>, and add B<xxx_err.c> to the Makefile.
Running B<make errors> will then generate a file B<xxx_err.c>, and
add all error codes used in the library to B<xxx.h>.
Additionally the library include file must have a certain form.
Typically it will initially look like this:
#ifndef HEADER_XXX_H
#define HEADER_XXX_H
#ifdef __cplusplus
extern "C" {
#endif
/* Include files */
#include <openssl/bio.h>
#include <openssl/x509.h>
/* Macros, structures and function prototypes */
/* BEGIN ERROR CODES */
The B<BEGIN ERROR CODES> sequence is used by the error code
generation script as the point to place new error codes, any text
after this point will be overwritten when B<make errors> is run.
The closing #endif etc will be automatically added by the script.
The generated C error code file B<xxx_err.c> will load the header
files B<stdio.h>, B<openssl/err.h> and B<openssl/xxx.h> so the
header file must load any additional header files containing any
definitions it uses.
=head1 USING ERROR CODES IN EXTERNAL LIBRARIES
It is also possible to use OpenSSL's error code scheme in external
libraries. The library needs to load its own codes and call the OpenSSL
error code insertion script B<mkerr.pl> explicitly to add codes to
the header file and generate the C error code file. This will normally
be done if the external library needs to generate new ASN1 structures
but it can also be used to add more general purpose error code handling.
=head1 INTERNALS
The error queues are stored in a thread-local storage with one B<ERR_STATE>
entry for each thread. ERR_get_state() returns the current thread's
B<ERR_STATE>. An B<ERR_STATE> can hold up to B<ERR_NUM_ERRORS> error
codes. When more error codes are added, the old ones are overwritten,
on the assumption that the most recent errors are most important.
Error strings are also stored in a hash table that can be obtained
by calling ERR_get_string_table(void).

=head1 DESCRIPTION
Since the introduction of the ENGINE API, the recommended way of controlling
default implementations is by using the ENGINE API functions. The default
B<RAND_METHOD>, as set by RAND_set_rand_method() and returned by
RAND_get_rand_method(), is only used if no ENGINE has been set as the default
"rand" implementation. Hence, these two functions are no longer the recommended
way to control defaults.
If an alternative B<RAND_METHOD> implementation is being used (either set
directly or as provided by an ENGINE module), then it is entirely responsible
for the generation and management of a cryptographically secure PRNG stream. The
mechanisms described below relate solely to the software PRNG implementation
built in to OpenSSL and used by default.
These functions implement a cryptographically secure pseudo-random
number generator (PRNG). It is used by other library functions for
example to generate random keys, and applications can use it when they
need randomness.
A cryptographic PRNG must be seeded with unpredictable data such as
mouse movements or keys pressed at random by the user. This is
described in L<RAND_add(3)>. Its state can be saved in a seed file
(see L<RAND_load_file(3)>) to avoid having to go through the
seeding process whenever the application is started.
L<RAND_bytes(3)> describes how to obtain random data from the
PRNG.
