## p-25519 / eddsa support ## p-25519 / eddsa support
OpenKeychain supports elliptic curve cryptography, but only the ECDSA and ECDH algorithms as specified in [RFC 6637](https://tools.ietf.org/html/rfc6637), which only support the NIST curves. To support the p-25519 curve requires support for EdDSA as specified in [this Internet Draft](http://www.ietf.org/id/draft-koch-eddsa-for-openpgp-01.txt) by Werner Koch. This is also a requirement for compatibilty with OpenPGP keys generated by [Google End to End](https://github.com/google/end-to-end). This task includes implementing EdDSA in the [BouncyCastle](https://www.bouncycastle.org/) library, which OpenKeychain uses for its low-level crypto operations, and adding support for it in OpenKeychain's UI itself.
TODO: Vincent **Expected results:** Working implementation of p-25519 EC crypto in OpenKeychain
**Knowledge Prerequisite:** Java programming, Elliptic Curve cryptography
**Skill level:** hard
**Mentor:** Vincent Breitmoser

## Improve unit tests ## Improve unit tests
Unit tests are important, especially for a security-related application like OpenKeychain. We have a reasonable amount of unit tests which covers critical parts of our crypto code for a total of 25% coverage. Testing on Android has come a long way since last year though, so this task is about exploring those new possibilities and seriously improving that coverage, including UI and API test cases.
