httpd htpasswd Command

Hrf:https://www.cnblogs.com/f-ck-need-u/p/8413490.html

HTPASSWD is used to generate a password based on Web user authentication for a specified user, provided by the Httpd-tools package. Supports 3 encryption algorithms: MD5, Sha, and the Crypt () function on the system, which defaults to MD5 when no algorithm is specified.

HTPASSWD [-c] [m] [d] passwdfile username
htpasswd-b [-c] [m |-d |-P |-S] [-d] passwdfile username Password
htpasswd-n [m |-d |-S |-p] username
htpasswd-nb [-M |-d |-S |-p] Username password
option Description:
passwdfile: A user password file that contains the user name and its password. If the "-C" option is used, the file is created or overwritten. You must specify the Passwdfile parameter when you do not use the "-n" option.
Username: Creates a password for the specified user name. If the user record already exists, it is updated. -
c: Create user password file Passwdfile, overwriting existing files if the file already exists. Cannot be used with "-N". -
N: Outputs the results in standard output instead of writing them to the user's password file. This option ignores the user password file passwdfile parameter. cannot be used with the "-C" option. -
m: Use the MD5 encryption algorithm. Default. -
D: It is not safe to use the crypt () function to compute the password.
-S: Use the SHA encryption algorithm. Safety.
-P: Force unencrypted password, keep plaintext state, unsafe.
-B: Force bcrypt encryption password, very safe.
-D: Deletes the specified user and password from the user's password file.
-B: Use batch mode, or Non-interactive mode, to pass plaintext passwords directly to the encryption.
Password: Specifies the plaintext password to enter. Can only be used in batch mode, that is, with "-B".

For example:

(1). Use the "-n" option to output the results directly to the standard output without creating a passwdfile.

[Root@xuexi ~]# htpasswd-n Jim
New password: 
re-type new password: 
Jim:zkhud9tzigucy

(2). Pass a password directly using batch mode.

[Root@xuexi ~]# htpasswd-nb Jim 123456; HTPASSWD-NB Jim 123456
Jim:r.bf8rvw56boa

JIM:XXONGOS8NN3LQ

The password was found to be completely random.

(3). Create user password file passwdfile.

[Root@xuexi ~]# HTPASSWD-CB bobfile Bob 123456
[Root@xuexi ~]# cat Bobfile 
BOB:FVUXZB3KCNDPK

(4). Deletes a user in the user file.

[Root@xuexi ~]# htpasswd-d bobfile Bob

(5). Use the SHA and MD5 encryption algorithms to calculate passwords.

[Root@xuexi ~]# htpasswd-mb bobfile Bob 123456
[Root@xuexi ~]# cat bobfile 
Bob: $apr 1$bllkodft$ Gumeb8hxngoaschs1sbgq0
[Root@xuexi ~]# htpasswd-sb bobfile Bob 123456 
[Root@xuexi ~]# cat Bobfile
