I want to access a URL that requires a username/password.I want to try it curl Access it.Now I'm doing something similar:

Pass HTTP Authentication in cURL Sometime, websites will require a username and password to view the content (can be done with.htaccess file). With the help of -u option, we can pass those credentials from cURL to the web server as shown below. $ curl -u username:password URL.

Enter the username and Password and then make a CURL call as usual. Except that you do not have to use the –user (or) -u flag or enter clear text password. The SecureCLI will take care of encrypting your username and password into the Base64 format and appends it to the Authorization Request Header. This curl method keeps credentials out of the history and process status, but leaves username and password in cleartext in the my-password-file creating another attack vector - worse than than having info in the history file: bash, for example, automatically restricts permissions of the history file.

I got an error.I think I need to specify a username and password as well as the above commands.

How can I do this?

#1st floor

Same but different grammar

#2nd floor

You can also send a user name by:

Freestyle librelink mac software download 800 number. Curl then asks you for your password and it will not be visible on the screen (or do you need to copy/paste commands).

#3rd floor

Use the -u flag to include the user name, and curl prompts for the password:

You can also include a password in the command, but your password will appear in the bash history:

#4th floor

This is safer:

.. because passing a normal user/password string on the command line is a bad idea.

The format of the password file is (press man curl):

Be careful:

1. Machine name must not contain https://or similar name!Host name only.
2. 'machine', 'login' and 'password' are just keywords; the actual information is what follows those keywords.

#5th floor

In order for the password to at least not pop up in your.bash_history:

Curl Ftp Username Password

In short, the safest way is to use environment variables to store/retrieve credentials.Therefore, the curl command is as follows:

Then, your WWW_Authentication api will be called and the http WWW_Authentication header API_HASH with the Base64 encoding values of API_USER and API_HASH will be used.-Lk simply tells curl to follow http 30x redirection and use unsafe tls processing (that is, ignore ssl errors).Double--just bash's grammatical sugar stop processing command line flag.In addition, -b cookies.txt and-c cookies.txt flags use-b to send cookies and-c to store cookies locally to process cookies.

If you are using a system with a Gnome Keyring application, the solution to avoid direct password exposure is to use gkeyring.py From Key ring Extract password from:

You can use the following commands:

The HTTP password will then be triggered.

To safely pass the password in the script (that is, to prevent it from being displayed with ps auxf or the log), you can use the -K-flag (reading the configuration from stdin) and heredoc to execute:

I have the same requirements for bash (Ubuntu 16.04 LTS), and the commands provided in the answer do not work properly in my case.I have to use:

You only need to use double quotes in the -F parameter if you are using variables, so from the command line.. -F'username=myuser'.. You can.

Other answers also suggest that netrc specify a user name and password based on what I read.Here are some syntax details:

Like other answers, I would like to emphasize the need to be aware of the security of this issue.

Although I am not an expert, I find these links insightful:

To summarize:

Using the encrypted versions of the protocol (HTTPS and HTTP) (FTPS and FTP) can help prevent network leaks.

Using netrc can help prevent command line leaks.

Curl Pass Credentials

Further, it appears that you can also encrypt netrc files using gpg

In this way, your credentials are not 'at rest' (stored) as plain text.

Very simple, please do the following:

Usually the CURL command is called

If you don't have any passwords or want to skip the command prompt to require a simple password, leave the password section blank.

That is curl https://example.com?Param=ParamValue-u USERNAME:

Curl With Username And Password

The safest way to prompt for credentials to be passed to curl is to prompt for credentials to be inserted.This happens when the user name is passed as previously suggested (-u USERNAME).

Curl With Username And Password Prompt

But what if you can't pass your user name this way?For example, the user name may need to be part of the url, and only the password is part of the json payload.

tl; dr: In this case, this is the safe way to use curl:

read prompts for a user name and password from the command line and stores the submitted values in two variables that can be referenced in subsequent commands and not set.

I will elaborate on why other solutions are not ideal.

Why are environment variables unsafe

1. Since the environment is implicitly available to processes, it is not possible to track access to and public mode of environment variable content (ps-eww)
2. Applications typically capture the entire environment and record it for debugging or monitoring (sometimes log files are recorded in plain text on disk, especially after an application crashes)
3. Environment variables are passed to child processes (thus violating the principle of minimum privilege)
4. Maintaining them is a problem: new engineers don't know where they are or what needs are around them - for example, don't pass them on to subprocesses - because they are not executed or documented.

Why it is not safe to type a command directly on the command line, because your secret will eventually be seen by any other user running ps-aux because it lists the commands submitted for each currently running process.It is also because your key subsequently appears in the bash history (once the shell terminates).

Why is it unsafe to include it in a local file? Strict POSIX access restrictions on this file can mitigate this risk.However, it is still a file on the file system and is not encrypted when static.

16th floor

This is much more demanding than OP, but since this is the best result of securely passing passwords to curl, I've added these solutions here for others who arrive here.

Note: -s arg for read command is not POSIX, so it is not available everywhere, so it will not be used below.We'll use stty-echo and stty echo instead.

Note: If in a function, all bash variables below can be declared locals, not unset.

Note: perl is fairly common on all systems I've tried, because it's dependent on many things, whereas Ruby and python are not, so use perl here.If you can guarantee that ruby / python is executed in it, you can replace the perl command with its equivalent.

Note: Tested in bash 3.2.57 on macOS 10.14.4.Other shells/installations may require some minor translation.

Securely prompt the user to enter (reusable) passwords for curling.This is particularly useful if you need to call curl more than once.

For modern shells, echo is built in (by checking which echo):

For older shell s, echo is similar to/bin/echo (you can see any echo of it in the process list):
This version cannot reuse this password. Please lower the password instead.

If you happen to need to temporarily store the password in a file, reuse it for multiple commands before clearing the password (for example, because you are using functions to reuse the code, do not want to duplicate the code, and cannot pass values through echo).(Yes, in this case they don't have functionality in different libraries, so they're a bit cheating; I'm trying to reduce them to the minimum code needed to display them.)

When echo is built-in (this is specially designed because echo is built-in but provided for integrity reasons):

When echo is something of the/bin/echo class:
