NAME¶
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.
