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.
- Use the crypt algorithm (default).:
- Use the MD5 based BSD password algorithm 1.:
- 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.:
- Read passwords from stdin.:
- Don't verify when reading a password from the terminal.:
- Don't output warnings when passwords given at the command line are truncated.:
- In the output list, prepend the cleartext password and a TAB character to each password hash.:
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.
