Placeholders

Keyguard replaces placeholders when performing an action with the field (copying, opening in a browser and more). The feature is largely based on the Keepass's specification.

At this moment placeholders are supported in:

• URL field;
• URL override commands.

Basics:

• placeholders and their basics parameters are case-insensitive;
• placeholders are resolved using the shared constant time, all time-sensitive placeholders will be synced;
• if no value is found, the placeholder will be replaced with an empty string: {otp} will be replaced with an empty string if an entry doesn't have one-time password configured;
• if no placeholder is found, the placeholder will be kept in it's original form: {keyguard} will be replaced with {keyguard}.

Types

Entry Core

Placeholder	Description
uuid	UUID
title	Title/Name
username	Username
password	Password
otp	One-time password
notes	Notes
favorite	Favorite

Example:

> https://example.com?user={username}
https://example.com?user=joe

Entry Custom Field

Custom strings can be referenced using {s:name}. For example, if you have a custom string named "Email", you can use the placeholder {s:email}.

Placeholder	Description
s:value	First of the custom fields named 'value'

Example:

> https://example.com?license={s:license}
https://example.com?license=12345678ABCD

Entry URL

*URL override specific*

This is useful in URL override command field. You can extract data from the URL for your new command.

Note: {base} supports exactly the same parts as {url} and is identical to it.

Placeholder	Description
url	URL: https://user:pw@keepass.info:80/path/example.php?q=e&s=t
url:rmvscm	URL without scheme name: user:pw@keepass.info:80/path/example.php?q=e&s=t
url:scm	Scheme name: https
url:host	Host: keepass.info
url:port	Port: 80
url:path	Path: /path/example.php
url:query	Query: ?q=e&s=t
url:userinfo	User information: user:pw
url:username	Username: user
url:password	Password: pw

Text transformation

Replace text using regular expression

t-replace-rx:/text/search/replace/

the first symbol after : defines the separator. It may be any symbol except { and }. Trailing separator symbol is required.

Example:

Let the username field contain the email address 'username@example.com', then:

> {t-replace-rx:/{username}/.*@(.*)/$1/}
example.com

for more info how it works, see the underlying implementation's documentation

Convert text to the other representation

t-conv:/value/type/

the first symbol after : defines the separator. It may be any symbol except { and }. Trailing separator symbol is required.

• u or upper - transforms 'value' component into the uppercase basing on the English locale;
• l or lower - transforms 'value' component into the lowercase basing on the English locale;
• base64 - encodes 'value' component into the Base64 (no padding, no wrap, URL safe) representation of the text;
• hex - encodes 'value' component into the HEX (lowercase) representation of the text;
• uri - encodes 'value' component into the URI representation of the text;
• uri-dec - decodes 'value' component from the URI representation of the text to the text;

Example:

> https://example.com?user={username}&password={t-conv:/{password}/uri/}
https://example.com?user=joe&password=Password1%21

Environmental variables

System environment variables are supported. The name of the variable must be enclosed in % characters.

Example:

> {%HOME%}
/home/username
