-For security reasons, fingerprint provided in session URL does not override any fingerprint already cached on the machine. This for instance differs from behavior, when fingerprint is provided using ''-hostkey'' switch of ''[[scriptcommand_open|open]]'' command in scripting.+A syntax to serialize raw site settings is '';x-name1=value1;x-name2=value2'' (inserted after username and password).
-Format of the fingerprint for URL((Fingerprint format for URL is based by [[http://tools.ietf.org/html/draft-ietf-secsh-scp-sftp-ssh-uri|draft-ietf-secsh-scp-sftp-ssh-uri]].)) somewhat differs from format used in other WinSCP features (''-hostkey'' switch of ''[[scriptcommand_open|open]]'' command in scripting for instance). To convert WinSCP fingerprint format to URL format:+For example to use an HTTP proxy server ''proxy'', use the following %%URL%%: \\ ''%%sftp://username:password;x-proxymethod=3;x-proxyhost=proxy@example.com/%%''
-  - Drop bit count part (the number after ''ssh-rsa'' or ''ssh-dsa'', typically ''2048'' or ''1024''); +To have WinSCP generate a session %%URL%% with the advanced settings, check //Advanced settings// on [[ui_generateurl|Generate session URL/code]] dialog. To serialize all session settings for a WinSCP extension, use ''!E'' [[custom_command#patterns|pattern]].

-For example WinSCP fingerprint ''ssh-rsa 2048 ee:f3:c1:59:4d:b4:e2:c5:da:22:3a:6e:97:a0:28:29'' converts to ''ssh-rsa-ee-f3-c1-59-4d-b4-e2-c5-da-22-3a-6e-97-a0-28-29''.+When [[integration_url|using the URL in webbrowser]], note that this syntax is not compatible with Chrome M130 and newer (and Edge based on it), as Chrome re-encodes the ==semicolons==. Workaround is to drop the ''%%//%%'' separator after the protocol from the URL. Such format is acceptable for WinSCP and prevents Chrome from reinterpreting the URL.
-===== Special Characters =====+===== [[hostkey]] SSH Host Key Fingerprint ===== 
 + 
 +There's a special syntax to include an expected [[ssh_verifying_the_host_key|SSH host key fingerprint]] in SFTP/SCP %%URL%% among advanced site settings: ''fingerprint=<fingerprint>''. 
 + 
 +For security reasons, fingerprint provided in session %%URL%% does not override any fingerprint already cached on the machine. This for instance differs from behavior, when fingerprint is provided using ''[[scriptcommand_open#hostkey|-hostkey]]'' switch of ''[[scriptcommand_open|open]]'' command in scripting. 
 + 
 +Format of the fingerprint for %%URL%%((Fingerprint format for %%URL%% is based on [[https://datatracker.ietf.org/doc/html/draft-ietf-secsh-scp-sftp-ssh-uri-04|draft-ietf-secsh-scp-sftp-ssh-uri]].)) somewhat differs from format used in other WinSCP features (''[[scriptcommand_open#hostkey|-hostkey]]'' switch of ''[[scriptcommand_open|open]]'' command in scripting for instance). To convert WinSCP fingerprint format to %%URL%% format: 
 + 
 +  - Drop bit count part (the number after ''ssh-rsa'', ''ssh-dss'', etc., typically ''2048'' or ''1024''); 
 +  - Replace the remaining space with a dash sign (''-''). 
 +  - Pluses (''+'') and slashes (''/'') in SHA-256 hash need to be [[#special|encoded]] or replaced with dashes (''-'') and underscores (''_'') respectively.((In case you are still using MD5 fingerprints, replace all colons ('':'') with a dash sign (''-'') too. Though you should switch to SHA-256 fingerprints.)) 
 + 
 +For example WinSCP fingerprint ''ssh-rsa 2048 2EP3avJqmpRtSRaUIqwrzavm15vssrhHxJWh9mBaz8M'' converts to ''ssh-rsa-2EP3avJqmpRtSRaUIqwrzavm15vssrhHxJWh9mBaz8M''.

 +===== [[special]] Special Characters =====
Special characters (like ''@'' in username, see example below) have to be encoded using ''%XX'' syntax, where ''XX'' is hexadecimal UTF-8 code.((For multi-byte codes, use ''%'' before every byte, for instance to represent pound-sign ''£'' use ''%C2%A3''.))

  * space: ''%20'' or ''+''   * space: ''%20'' or ''+''
 +  * ''#'': ''%23'' (number sign/hash)
  * ''%'': ''%25'' (percent sign)   * ''%'': ''%25'' (percent sign)
  * ''+'': ''%2B'' (plus sign)   * ''+'': ''%2B'' (plus sign)
Line 50: Line 66:
Note that when specifying session %%URL%% on [[commandline|command-line]], you cannot use characters that have special meaning on Windows command-line, just as with any other command-line argument. Such characters include ''&'' (ampersand), ''|'' (pipe), ''<'' (less-than sign), ''>'' (greater-than sign), ''%%"%%'' (double-quote). To escape these characters, you can wrap whole session %%URL%% to double-quotes (''%%"%%'') or encode the characters as shown above. Note that when specifying session %%URL%% on [[commandline|command-line]], you cannot use characters that have special meaning on Windows command-line, just as with any other command-line argument. Such characters include ''&'' (ampersand), ''|'' (pipe), ''<'' (less-than sign), ''>'' (greater-than sign), ''%%"%%'' (double-quote). To escape these characters, you can wrap whole session %%URL%% to double-quotes (''%%"%%'') or encode the characters as shown above.
 +
 +Further, in Windows batch files, ''%'' (percent sign) needs to be doubled to be used correctly, even when the sign is itself used to encode other special characters. For example, to use ''@'' in a username, specify ''<nowiki>%%40</nowiki>''. Other programming and scripting languages have other special characters that need to be escaped using a construct of the respective language (for example ''$'' in PowerShell has to be escaped as ''`$'').
 +
 +You can have WinSCP [[ui_generateurl|generate correct URL]] for all kinds of uses (command-line, script or batch file).
 +
 +To avoid having to URL-encode the credentials, particularly when sourcing them from a variable, you can use ''-username'' and ''-password'' switches of the [[scriptcommand_open#username|''open'' command]] or [[commandline#username|WinSCP command-line]].

-===== Generating ===== 
-You can have WinSCP [[ui_generateurl|generate session URL]]. &beta_feature 
-You can use [[custom_command|custom command]] pattern ''!S'' to pass a session %%URL%% to other processes.+===== [[file]] Directory or File URL ===== 
 + 
 +A [[commandline#session|URL specified on command-line]] can include an initial remote path (the path has to end with a slash): \\ 
 +''%%sftp://username@example.com/remote/path/%%'' 
 + 
 +You can also include a file path into the URL: \\ 
 +''sftp://username@example.com/remote/path/file.txt'' 
 + 
 +By default, it will initiate the file  [[task_download#url|download]]. When combined with [[commandline#operations|''/browse'' switch]], the file will instead be selected in a [[ui_file_panel|file panel]]. 
 + 
 +===== [[other]] Other Uses ===== 
 + 
 +You can also [[ui_login#pasting|paste the session URL on Login dialog]] or [[clipboard#url|main window]] or even Windows File Explorer or web browser (if WinSCP is [[integration_url|registered]] to handle file transfer protocol %%URL%% addresses). You can use the session URL as a way to [[config#transfer|transfer site settings]]. 
 + 
 +You can use [[custom_command|custom command]] patterns ''!E'' or ''!S'' to pass a session %%URL%% to other processes.
