Appendix E Generating somewhat random passwords ¶

This section documents a library generating random passwords; the library file is libmbfl-passwords.bash. We can load this library at run–time with:

mbfl_load_library(/path/to/libmbfl-passwords.bash)

for details Libraries loading and embedding. Notice that the preprocessor option --print-libmbfl-passwords will print the file pathname of the installed library, Invoking the preprocessor.

Usually we want to use the passwords–generating functions as follows:

{
    mbfl_declare_varref(PASSWD_STRING)
    mbfl_passwords_printable_ascii_noblank mbfl_datavar(PASSWD_STRING) 8
    echo "$PASSWORD_STRING"
}
