UNIX even has the isatty() call for secure applications, to check whether stdin is a terminal or not, but I've mostly found these sort of apps ignore stdin and grab /dev/tty directly. This is handy since it allows things to successfully prompt for a password even when they're buried deep in a pipe chain.

openssl_passwd
PASSWD(1) OpenSSL PASSWD(1)
NAME
passwd - compute password hashes
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] {password}
DESCRIPTION
The passwd command computes the hash of a password typed at run-time or the hash of each password in a list. The password list is taken
from the named file for option -in file, from stdin for option -stdin, or from the command line, or from the terminal otherwise. The Unix
standard algorithm crypt and the MD5-based BSD password algorithm 1 and its Apache variant apr1 are available.
OPTIONS
-crypt
Use the crypt algorithm (default).
-1 Use the MD5 based BSD password algorithm 1.
-apr1
Use the apr1 algorithm (Apache variant of the BSD algorithm).
-salt string
Use the specified salt. When reading a password from the terminal, this implies -noverify.
-in file
Read passwords from file.
-stdin
Read passwords from stdin.
-noverify
Don't verify when reading a password from the terminal.
-quiet
Don't output warnings when passwords given at the command line are truncated.
-table
In the output list, prepend the cleartext password and a TAB character to each password hash.
EXAMPLES
openssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.
openssl passwd -1 -salt xxxxxxxx password prints $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..
openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
