# Crate deprecated This crate is deprecated in favor of [openpgp-card-rpgp](https://crates.io/crates/openpgp-card-rpgp). `openpgp-card-sequoia` is based on the legacy `openpgp-card` 0.4 API. It is no longer under development. The next generation `openpgp-card` version 0.5 includes bugfixes and new features (including additional KDF support), which I won't be backporting to this crate. You are welcome to use `openpgp-card-sequoia` as is, but be aware that the library will see no further work and also no bugfix or security releases. If you have any questions about porting existing client code, feel free to reach out.
