old_des fix windows build, remove docs

Single-key DES is insecure due to its short key size.  ECB mode is

not suitable for most applications; see L<des_modes(7)|des_modes(7)>.

=head1 HISTORY

In OpenSSL 0.9.7, all des_ functions were renamed to DES_ to avoid

clashes with older versions of libdes.  Compatibility des_ functions

are provided for a short while, as well as crypt().

Declarations for these are in <openssl/des_old.h>. There is no DES_

variant for des_random_seed().

This will happen to other functions

as well if they are deemed redundant (des_random_seed() just calls

RAND_seed() and is present for backward compatibility only), buggy or

already scheduled for removal.

des_cbc_cksum(), des_cbc_encrypt(), des_ecb_encrypt(),

des_is_weak_key(), des_key_sched(), des_pcbc_encrypt(),

des_quad_cksum(), des_random_key() and des_string_to_key()

are available in the MIT Kerberos library;

des_check_key_parity(), des_fixup_key_parity() and des_is_weak_key()

are available in newer versions of that library.

des_set_key_checked() and des_set_key_unchecked() were added in

OpenSSL 0.9.5.

des_generate_random_block(), des_init_random_number_generator(),

des_new_random_key(), des_set_random_generator_seed() and

des_set_sequence_number() and des_rand_data() are used in newer

versions of Kerberos but are not implemented here.

des_random_key() generated cryptographically weak random data in

SSLeay and in OpenSSL prior version 0.9.5, as well as in the original

MIT library.

=head1 NAME

des_read_password, des_read_2passwords, des_read_pw_string, des_read_pw -

Compatibility user interface functions

=head1 SYNOPSIS

 #include <openssl/des_old.h>

 int des_read_password(DES_cblock *key,const char *prompt,int verify);

 int des_read_2passwords(DES_cblock *key1,DES_cblock *key2,

 	const char *prompt,int verify);

 int des_read_pw_string(char *buf,int length,const char *prompt,int verify);

 int des_read_pw(char *buf,char *buff,int size,const char *prompt,int verify);

=head1 DESCRIPTION

The DES library contained a few routines to prompt for passwords.  These

aren't necessarely dependent on DES, and have therefore become part of the

UI compatibility library.

des_read_pw() writes the string specified by I<prompt> to standard output

turns echo off and reads an input string from the terminal.  The string is

returned in I<buf>, which must have spac for at least I<size> bytes.

If I<verify> is set, the user is asked for the password twice and unless

the two copies match, an error is returned.  The second password is stored

in I<buff>, which must therefore also be at least I<size> bytes.  A return

code of -1 indicates a system error, 1 failure due to use interaction, and

0 is success.  All other functions described here use des_read_pw() to do

the work.

des_read_pw_string() is a variant of des_read_pw() that provides a buffer

for you if I<verify> is set.

des_read_password() calls des_read_pw() and converts the password to a

DES key by calling DES_string_to_key(); des_read_2password() operates in

the same way as des_read_password() except that it generates two keys

by using the DES_string_to_2key() function.

=head1 NOTES

des_read_pw_string() is available in the MIT Kerberos library as well, and

is also available under the name EVP_read_pw_string().
