Lintian tag: obsolete-crypt-alias

Type: error

Description (from lintian-explain-tags)

The listed ELF binary appears to use the C library function fcrypt, which
is a less-portable alias for crypt. Programs that use this function cannot
be linked against the libcrypt.so provided by glibc 2.28 and higher.

The program should be changed to use crypt instead.

A false positive for this check is possible if the binary expects the
definition of fcrypt to come from some shared library other than
libcrypt.so, *and* that shared library defines this function to do
something other than hash passphrases. If this is the case it is
appropriate to override this tag.
