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. |
