|
|
|
|
|
|
<p>In the GNU C Library (glibc) from version 2.17 onwards, the crypt()
|
|
|
|
|
|
function call can return NULL when the salt violates specifications or
|
|
|
|
|
|
the system is in FIPS-140 mode and a DES or MD5 hashed password is
|
|
|
|
|
|
passed. When Cyrus-SASL’s authentication mechanisms call crypt(), a
|
|
|
|
|
|
NULL may be returned.
