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.
