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 stan- dard 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 char- acter 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$dxH- fLAsjHkDRmG83UXe8K0. 0.9.9-dev 2003-07-24 PASSWD(1)
