## PGPainless API with pgpainless-core
|
|
|
|
The `pgpainless-core` module contains the bulk of the actual OpenPGP implementation.
|
|
|
|
This is a quickstart guide. For more in-depth exploration of the API, checkout [](indepth.md).
|
|
|
|
:::{note}
|
|
This chapter is work in progress.
|
|
:::
|
|
|
|
### Setup
|
|
|
|
PGPainless' releases are published to and can be fetched from Maven Central.
|
|
To get started, you first need to include `pgpainless-core` in your projects build script:
|
|
|
|
```
|
|
// If you use Gradle
|
|
...
|
|
dependencies {
|
|
...
|
|
implementation "org.pgpainless:pgpainless-core:XYZ"
|
|
...
|
|
}
|
|
|
|
// If you use Maven
|
|
...
|
|
<dependencies>
|
|
...
|
|
<dependency>
|
|
<groupId>org.pgpainless</groupId>
|
|
<artifactId>pgpainless-core</artifactId>
|
|
<version>XYZ</version>
|
|
</dependency>
|
|
...
|
|
</dependencies>
|
|
```
|
|
|
|
This will automatically pull in PGPainless' dependencies, such as Bouncy Castle.
|
|
|
|
:::{important}
|
|
Replace `XYZ` with the current version, in this case {{ env.config.version }}!
|
|

|
|
|
|
The entry point to the API is the `PGPainless` class.
|
|
For many common use-cases, examples can be found in the
|
|
{{ '[examples package](https://{}/main/pgpainless-core/src/test/java/org/pgpainless/example)'.format(repo_pgpainless_src) }}.
|
|
There is a very good chance that you can find code examples there that fit your needs.
|
|
|
|
### Read and Write Keys
|
|
Reading keys from ASCII armored strings or from binary files is easy:
|
|
|
|
```java
|
|
String key = "-----BEGIN PGP PRIVATE KEY BLOCK-----\n"...;
|
|
PGPSecretKeyRing secretKey = PGPainless.readKeyRing()
|
|
.secretKeyRing(key);
|
|
```
|
|
|
|
Similarly, keys or certificates can quickly be exported:
|
|
|
|
```java
|
|
// ASCII armored key
|
|
PGPSecretKeyRing secretKey = ...;
|
|
String armored = PGPainless.asciiArmor(secretKey);
|
|
|
|
// binary (unarmored) key
|
|
byte[] binary = secretKey.getEncoded();
|
|
```
|
|
|
|
### Generate a Key
|
|
PGPainless comes with a method to quickly generate modern OpenPGP keys.
|
|
There are some predefined key archetypes, but it is possible to fully customize the key generation to fit your needs.
|
|
|
|
```java
|
|
// EdDSA primary key with EdDSA signing- and XDH encryption subkeys
|
|
PGPSecretKeyRing secretKeys = PGPainless.generateKeyRing()
|
|
.modernKeyRing("Romeo <romeo@montague.lit>", "thisIsAPassword");
|
|
|
|
// RSA key without additional subkeys
|
|
PGPSecretKeyRing secretKeys = PGPainless.generateKeyRing()
|
|
.simpleRsaKeyRing("Juliet <juliet@montague.lit>", RsaLength._4096);
|
|
```
|
|
|
|
As you can see, it is possible to generate all kinds of different keys.
|
|
|
|
### Extract a Certificate
|
|
If you have a secret key, you might want to extract a public key certificate from it:
|
|
|
|
```java
|
|
PGPSecretKeyRing secretKey = ...;
|
|
PGPPublicKeyRing certificate = PGPainless.extractCertificate(secretKey);
|
|
```
|
