passwd − compute password hashes |
|
openssl passwd [−crypt] [−1] [−apr1] [−salt string] [−in file] [−stdin] [−noverify] [−quiet] [−table] {password} |
|
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. |
|
−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. |

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. |
