Hello,
man muss ja manchmal nur erst auf die Idee kommen zu suchen, dann finden und lesen:
http://httpd.apache.org/docs/current/programs/htpasswd.html
-m
Use MD5 encryption for passwords. This is the default (since version 2.2.18).
-B
Use bcrypt encryption for passwords. This is currently considered to be very secure.
-C
This flag is only allowed in combination with -B (bcrypt encryption). It sets the computing time used for the bcrypt algorithm (higher is more secure but slower, default: 5, valid: 4 to 31).
-d
Use crypt() encryption for passwords. This is not supported by the httpd server on Windows and Netware. This algorithm limits the password length to 8 characters. This algorithm is insecure by today's standards. It used to be the default algorithm until version 2.2.17.
Liebe Grüße aus dem schönen Oberharz
