# User-IDs
|
|
|
|
User-IDs are identities that users go by. A User-ID might be a name, an email address or both.
|
|
User-IDs can also contain both and even have a comment.
|
|
|
|
In general, the format of a User-ID is not fixed, so it can contain arbitrary strings.
|
|
However, it is agreed upon to use the
|
|
Below is a selection of possible User-IDs:
|
|
|
|
```
|
|
Firstname Lastname (Comment) <email@address.tld>
|
|
Firstname Lastname
|
|
Firstname Lastname (Comment)
|
|
<email@address.tld>
|
|
```
|
|
|
|
PGPainless comes with a builder class `UserId`, which can be used to safely construct User-IDs:
|
|
|
|
```java
|
|
UserId nameAndEMail = UserId.nameAndEmail("Jane Doe", "jane@pgpainless.org");
|
|
assertEquals("Jane Doe <jane@pgpainless.org>", nameAndEmail.toString()):
|
|
|
|
UserId onlyEmail = UserId.onlyEmail("john@pgpainless.org");
|
|
assertEquals("<john@pgpainless.org>", onlyEmail.toString());
|
|
|
|
UserId full = UserId.newBuilder()
|
|
.withName("Peter Pattern")
|
|
.withEmail("peter@pgpainless.org")
|
|
.withComment("Work Address")
|
|
.build();
|
|
assertEquals("Peter Pattern (Work Address) <peter@pgpainless.org>", full.toString());
|
|
```
|
|
|
|
If you have a User-ID in form of a string (e.g. because a user provided it via a text field),
|
|
you can parse it into its components like this:
|
|
|
|
```java
|
|
String string = "John Doe <john@doe.corp>";
|
|
UserId userId = UserId.parse(string);
|
|
|
|
// Now you can access the different components
|
|
assertEquals("John Doe", userId.getName());
|
|
assertEquals("john@doe.corp", userId.getEmail());
|
|
assertNull(userId.getComment());
|
|
```
|
|
|
|
The method `UserId.parse(String string)` will throw an `IllegalArgumentException` if the User-ID is malformed.
