PGPainless is a wrapper around [Bouncycastle](https://www.bouncycastle.org/), which provides an easy to use, intuitive,
|
|
but also powerful API for OpenPGP ([RFC4880](https://datatracker.ietf.org/doc/html/rfc4880)).
|
|
|
|
Its primary functionality is encrypting, signing, decrypting and verifying data, as well as generating and modifying keys.
|
|
|
|
## Why should I use it?
|
|
|
|
> At FlowCrypt we are using PGPainless in our Kotlin code bases on Android and on server side.
|
|
> The ergonomy of legacy PGP tooling on Java is not very good, and PGPainless improves it greatly.
|
|
> We were so happy with our initial tests and with Paul - the maintainer, that we decided to sponsor further development of this library.

|
There are a bunch of reasons why you should consider switching to PGPainless:
|
|
|
|
### Easy to use API
|
|
|
|
One main focus of the project is ease of use.
|
|
Using Bouncycastle can be a hassle, since simple tasks require a substantial amount of boilerplate code and small
|
|
mistakes are easily made.
|
|
PGPainless aims at providing a simple interface to get the job done quickly, while not trading away functionality or
|
|
correctness.
|
|
|
|
For examples about how to use the API, see the projects
|
|
[readme](https://github.com/pgpainless/pgpainless/blob/master/README.md).
|
|
|
|
### Complementing Bouncycastle
|
|
|
|
**PGPainless has Bouncycastle truly figured out!**
|
|
|
|
If you already use BC in your code, PGPainless is a perfect complement!
|
|
It allows you to remove many lines of boilerplate code and offers you the certitude of a dedicated JUnit test suite.
|
|
|
|
Furthermore PGPainless is scoring *second place* on the very extensive [Sequoia OpenPGP Interoperability Test Suite](https://tests.sequoia-pgp.org).
|
|
|
|
We have studied BC intensively, identified its shortcomings and came up with solutions to those:
|
|
|
|
Contrary to vanilla BC and some other BC-based OpenPGP libraries, PGPainless does signature verification **the right way**.
|
|
It not only checks for signature *correctness*, but goes the extra mile to also check signature *validity* by taking into consideration key expiration dates, revocations, signature structures, etc.
|
|
|
|
Take a look at [this blog post](https://blog.jabberhead.tk/2021/04/03/why-signature-verification-in-openpgp-is-hard/) to get an idea of how complex signature verification with OpenPGP truly is.
|
|
|
|
### Android Support
|
|
PGPainless is designed to work on Android versions down to [API level 10](https://developer.android.com/about/versions/android-2.3.3) (Gingerbread).
|
|
This makes PGPainless a good choice for implementing OpenPGP encryption in your Android app.
|
|
|
|
Compatibility with certain Android APIs is ensured through [Animalsniffer](http://www.mojohaus.org/animal-sniffer/).
|
|
|
|
## Releases
|
|
PGPainless is released on the maven central repository. Including it in your project is simple:
|
|
|
|
Maven:
|
|
```xml
|
|
<dependency>
|
|
<groupId>org.pgpainless</groupId>
|
|
<artifactId>pgpainless-core</artifactId>
|
|
<version>0.2.13</version>
|
|
</dependency>
|
|
```
|
|
|
|
Gradle:
|
|
```gradle
|
|
repositories {
|
|
mavenCentral()
|
|
}
|
|
|
|
dependencies {
|
|
compile 'org.pgpainless:pgpainless-core:0.2.13'
|
|
}
|
|
```
|
|
|
|
There are [snapshot releases](https://oss.sonatype.org/content/repositories/snapshots/org/pgpainless/pgpainless-core/) available as well.
|
|
|
|
## Command Line Interface
|
|
|
|
PGPainless provides an implementation of the [Stateless OpenPGP Command Line Interface](https://datatracker.ietf.org/doc/html/draft-dkg-openpgp-stateless-cli-01)
|
|
in the `pgpainless-sop` module.
|
|
This allows PGPainless to be used as a command line application for encryption/decryption and signature creation/validation.
|
|
|
|
More importantly though, this allows to plug PGPainless into the [Sequoia OpenPGP Interoperability Test Suite](https://tests.sequoia-pgp.org/).
|
|
This extensive test suite demonstrates how closely PGPainless is following the standard, especially when it comes to signature verification.
|
|
|
|
## Security Audits
|
|
|
|
In late 2021, PGPainless was subject to an extensive security audit by the the pentesting
|
|
team of [Cure53](https://cure53.de). The audit was generously sponsored and arranged by [FlowCrypt.com](https://flowcrypt.com)!
|
|
|
|
Results of the audit [are publicly available here](assets/Audit-PGPainless.pdf).
|
|
Wherever possible, findings of the audit have been fixed in a timely manner.
|
|
|
|
## Forever Free Software
|
|
|
|
PGPainless is licensed under the Apache License 2.0 and this will never change.
|
|
|
|
**Free Libre Open Source Software Rocks!**
|

|
|
## About
|
|
PGPainless was created [during a Google Summer of Code project](https://blog.jabberhead.tk/summer-of-code-2018/),
|
|
for which an easy to use OpenPGP API for Java and Android was needed.
|
|
|
|
Originally we looked into forking [bouncy-gpg](https://github.com/neuhalje/bouncy-gpg),
|
|
but since support for lower Android versions was a requirement, PGPainless was born as an independent project.
|
|
In its early development stages the library was however influenced by bouncy-gpg written by Jens Neuhalje.
|
|
|
|
## Development
|
|
PGPainless is currently developed by [Paul Schaub (@vanitasvitae)](https://blog.jabberhead.tk).
