Escape @ character in git proxy password

I have git proxy config as 'http.proxy=http://userId:<b>pwd@123</b>@ipaddress:port'; but while cloning a remote project, I'm getting error as

Cloning into git...
error: Couldn't resolve proxy '123@ipaddress' while accessing http://git.kernel.org/pub/scm/git/git.git/info/refs

fatal: HTTP request failed

How to escape the '@' character in password?

Pls note: I cannot change the password.

I'd try using the URL Encoded value of the @ symbol (%40) if you're passing the password in the proxy url:

http.proxy=http://userId:pwd%40123@ipaddress:port

Note (November 2013)

Encoding the url (especially any special character in a password) is the right solution.
The .netrc mentioned below is only for remote repo url, not for the proxy used to resolve said remote repo url.

For said encoding, see "Percent-encoding":

> Percent-encoding, also known as URL encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. Although it is known as URL encoding it is, in fact, used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource Locator (URL) and Uniform Resource Name (URN). As such, it is also used in the preparation of data of the application/x-www-form-urlencoded media type, as is often used in the submission of HTML form data in HTTP requests. > > Reserved characters after percent-encoding:

!   #   $    &   '   (   )   *   +   ,   /   :   ;   =   ?   @   [   ]
%21 %23 %24 %26 %27 %28 %29 %2A %2B %2C %2F %3A %3B %3D %3F %40 %5B %5D

Original answer (May 2011)

Two comments:

• having a password for a server accessed with http (not https) is... strange. The password isn't encrypted during communications between client and server;

• you could setup a .netrc (or _netrc for Windows) in your $HOME, with the following content

  machine ipaddress:port
  login userId
  password pwd@
  

  The curl used by Git bbehind the scene would handle the encoding just fine, @ or no @.

URL encode any unusual characters.

List of url codes.

@ character is %40

In my git config file, I have encoded 'just' the user name for instance:

https://myemail%[email protected]/api.git

You have to percent-encode | encode the special characters. E.g. instead of this:

http://user:Pa@s@http-gateway.domain.org:80

you write this:

http://user:Pa%[email protected]:80

So @ gets replaced with %40.

For example, your password stored in environment variable GIT_PASSWORD, username - GIT_USERNAME, then:

git clone http://${GIT_USERNAME}:$(echo -n $GIT_PASSWORD | hexdump -v -e '"x" 1/1 "%02X"' | tr x %)@repository.git

Explanation of: echo -n $GIT_PASSWORD | hexdump -v -e '"x" 1/1 "%02X"' | tr x %

1. Print password: $GIT_PASSWORD <- hello
2. Convert 'hello' to hex: hello <- x68x65x6Cx6Cx6F
3. Change each 'x' to '%': x68x65x6Cx6Cx6F <- %68%65%6C%6C%6F
