  "description": "Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl truncates passwords with embedded NULLs.  Password parameters in PKCS12.xs are declared char *, which routes through Perl\u0027s default typemap to SvPV_nolen.  The Perl length is discarded.  The C code (or OpenSSL internally) calls strlen() on the buffer.  Any password byte at or after the first NULL is silently dropped. Binary / KDF-derived / HMAC-derived passwords lose entropy without any warnings.",
