NAME
des_read_password, des_read_2passwords, des_read_pw_string, des_read_pw -
Compatibility user interface functions
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);
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 prompt to standard output
turns echo off and reads an input string from the terminal. The string is
returned in buf, which must have spac for at least size bytes.
If 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 buff, which must therefore also be at least 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 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.
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().
