Hey HN, I shared an earlier prototype version of pgsodium but I just released 2.0 and felt this could be a good opportunity to share some updates! [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+. 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 provid

e 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. * 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. Check it out at: [https://github.com/michelp/pgsodium](https://github.com/mich... Please feel free to submit any issues you may have and as usual pull requests are greatly appreciated!
