Adds or modifies the password for user jsmith. The user is prompted for the password. If executed on a Windows system, the password will be encrypted using the modified Apache MD5 algorithm; otherwise, the system's crypt() routine will be used. If the file does not exist, htpasswd will do nothing except return an error. 初期値が追加、ってことじゃないの?
htpasswd -n[mdps] username htpasswd -nb[mdps] username password -c Create a new file. -n Don't update file; display results on stdout. -m Force MD5 encryption of the password. -d Force CRYPT encryption of the password (default). -p Do not encrypt the password (plaintext). -s Force SHA encryption of the password. -b Use the password from the command line rather than prompting for it. On Windows, TPF and NetWare systems the '-m' flag is used by default. On all other systems, the '-p' flag will probably not work.
