<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>UI_UTIL_read_pw_string()</code> asks for a passphrase, using <strong>prompt</strong> as a
|
|
prompt, and stores it in <strong>buf</strong>.
|
|
The maximum allowed size is given with <strong>length</strong>, including the
|
|
terminating NUL byte.
|
|
If <strong>verify</strong> is nonzero, the password will be verified as well.</p>
|
|
<p><code>UI_UTIL_read_pw()</code> does the same as <code>UI_UTIL_read_pw_string()</code>, the
|
|
difference is that you can give it an external buffer <strong>buff</strong> for the
|
|
verification passphrase.</p>
|
|
<p><code>UI_UTIL_wrap_read_pem_callback()</code> can be used to create a temporary
|
|
<strong>UI_METHOD</strong> that wraps a given PEM password callback <strong>cb</strong>.
|
|
<strong>rwflag</strong> is used to specify if this method will be used for
|
|
passphrase entry without (0) or with (1) verification.
|
|
When not used any more, the returned method should be freed with
|
|
<code>UI_destroy_method()</code>.</p>
|
|
<p>
|
|
</p>
|
|
<hr />
|
|
<h1><a name="notes">NOTES</a></h1>
|
|
<p><code>UI_UTIL_read_pw_string()</code> and <code>UI_UTIL_read_pw()</code> use default
|
|
<strong>UI_METHOD</strong>.
|
|
See <em>UI_get_default_method(3)</em> and friends for more information.</p>
|
|
<p>The result from the <strong>UI_METHOD</strong> created by
|
|
<code>UI_UTIL_wrap_read_pem_callback()</code> will generate password strings in the
|
|
encoding that the given password callback generates.
|
|
The default password prompting functions (apart from
|
|
<code>UI_UTIL_read_pw_string()</code> and <code>UI_UTIL_read_pw()</code>, there is
|
|
<code>PEM_def_callback()</code>, <code>EVP_read_pw_string()</code> and EVP_read_pw_string_min())
|
|
all use the default <strong>UI_METHOD</strong>.</p>

|
|
<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p><code>UI_UTIL_read_pw_string()</code> and <code>UI_UTIL_read_pw()</code> return 0 on success or a negative
|
|
value on error.</p>
|
|
<p><code>UI_UTIL_wrap_read_pem_callback()</code> returns a valid <strong>UI_METHOD</strong> structure or NULL
|
|
if an error occurred.</p>
