passwd - compute password hashes 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. 0.9.7a 2002-10-03 PASSWD(1)

openssl-passwd, passwd - compute password hashes SYNOPSIS
openssl passwd [-help] [-crypt] [-1] [-apr1] [-aixmd5] [-5] [-6] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] [-rand file...] [-writerand file] {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, its Apache variant apr1, and its AIX variant are available. OPTIONS
-help Print out a usage message. -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). -aixmd5 Use the AIX MD5 algorithm (AIX variant of the BSD algorithm). -5 -6 Use the SHA256 / SHA512 based algorithms defined by Ulrich Drepper. See <https://www.akkadia.org/drepper/SHA-crypt.txt>. -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. -rand file... A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS- dependent character. The separator is ; for MS-Windows, , for OpenVMS, and : for all others. [-writerand file] Writes random data to the specified file upon exit. This can be used with a subsequent -rand flag. EXAMPLES
