obsolete-crypt-alias

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.

Severity: error
Experimental: false
