## PGPainless API with pgpainless-core
Coming soon.
The `pgpainless-core` module contains the bulk of the actual OpenPGP implementation.
:::{note}
This chapter is work in progress.
:::
### Setup
bla
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
bla
PGPainless comes with a simple to use `KeyRingBuilder` class that helps you 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);
```
To generate a customized key, use `PGPainless.buildKeyRing()` instead:
```java
// Customized key
PGPSecretKeyRing keyRing = PGPainless.buildKeyRing()
.setPrimaryKey(KeySpec.getBuilder(
RSA.withLength(RsaLength._8192),
KeyFlag.SIGN_DATA, KeyFlag.CERTIFY_OTHER)
.overrideCompressionAlgorithms(CompressionAlgorithm.ZLIB)
).addSubkey(
KeySpec.getBuilder(ECDSA.fromCurve(EllipticCurve._P256), KeyFlag.SIGN_DATA)
).addSubkey(
KeySpec.getBuilder(
ECDH.fromCurve(EllipticCurve._P256),
KeyFlag.ENCRYPT_COMMS, KeyFlag.ENCRYPT_STORAGE)
).addUserId("Juliet <juliet@montague.lit>")
.addUserId("xmpp:juliet@capulet.lit")
.setPassphrase(Passphrase.fromPassword("romeo_oh_Romeo<3"))
.build();
```
As you can see, it is possible to generate all kinds of different keys.
### Extract a Certificate
bla
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);
```
