2.0.0 includes a ton of new feature and a few bug-fixes:
* Support for [XChaCha20-SIV](https://github.com/jedisct1/libsodium-xchacha20-siv) deterministic nonce-free encryption, this is useful for one-time workflows sacrificing a bit of speed and larger key size without worrying about nonce-handling issues.
* Support for [SignCryption](https://github.com/jedisct1/libsodium-signcryption) Sign & Encrypt identity verification. Signcryption goes beyond public key verification to provide identity verification, and negotiating a shared-secret key between two parties to use fast streaming encryption of the payload.
* Key id support for HMACSHA 512/256, generichash, and shorthash. This extends support for pgsodium's key management feature to these useful hash functions.
Praising sodium_malloc as secure annoys me. Its memset is definitely not secure. It is just not skipped, but it is not meltdown secure, so prone to sidechannel attacks. My fix was rejected, because a secure memset would be too slow (flushing the caches). So the headline should be fast crypto, in opposition to secure crypto.

[ 38.1 ms ] story [ 55.9 ms ] thread[pgsodium](https://github.com/michelp/pgsodium) 2.0.0 is a postgres extension that uses the [libsodium](https://doc.libsodium.org/) library to provide high-performance, modern cryptography support for PostgreSQL 10+.

* Support for low level [XChaCha20 streaming](https://libsodium.gitbook.io/doc/advanced/stream_ciphers/xch...). This is if you want to support your own low level algorithms on top of XChaCha20 for example, PASETO.
* More tests, docs, and small bug fixes in argument parsing
* In-memory key now protected with [sodium\_malloc](https://libsodium.gitbook.io/doc/memory_management), now the key has additional protection from over/underflow memory attack.
