| =head1 NAME |
| |
| des_read_password, des_read_2passwords, des_read_pw_string, des_read_pw - |
| Compatibility user interface functions |
| |
| =head1 SYNOPSIS |
| |
| 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(). |
