RustCrypto VS orion

I would say a toy (or personal-use-only) password manager is a relatively simple project. If we are to forget about the GUI parts, you need to determine serialization of your password database (bincode + serde should be enough) and how to encrypt it. For the latter you need only two algorithms: a password hash for deriving encryption key from password and optional salt (the latter is usually randomly generated and stored as a "key file"), and an AEAD algorithm for encrypting and decrypting serialized database. There are certain pitfalls with encryption (e.g. you should not reuse nonce with the same key, especially with modes like GCM) and with properly erasing sensitive data from memory, as well as preventing it from leaking to things like swap, but learning about those is part of the learning experience.

FYI: the rust-crypto crate is unmaintained. Take a look at https://github.com/RustCrypto/AEADs instead

For AEAD with AES, you may want to use RustCrypto (https://github.com/RustCrypto/AEADs.git) instead

Dexios is a secure command-line encryption tool, that uses audited crates provided by the RustCrypto Team.

This is in relation to RustCrypto/AEADs#421 - myself and another user are having the exact same issue.

I choose an AEDS crate from the RustCrypto group: AES-GCM in its SIV variant (the SIV variant isn't really needed but it doesn't cost much).

Use RustCrypto's aes with one of its block modes (https://docs.rs/block-modes/latest/block_modes/) or AEAD algorithms (https://github.com/RustCrypto/AEADs). There's a lot of modular stuff in RustCrypto, just need to browse a little 😉.

I'd recommend https://github.com/RustCrypto/AEADs. RustCrypto's crates are high quality, widely used and some have even been audited. Unfortunately they don't provide a read/write interface.

I'm the author and maintainer of a pure-Rust crypto library called Orion. I've been at it for a couple of years now, working on it in my spare time as well. There are a few people involved already, but we're still missing someone that is involved enough to be a "co-maintainer". There are some larger features that have been planned, but I lack the time currently to start too many new things. Of course, you can contribute in any amount you want.

Custom (the ones I have in the implementation I wrote)

With that said, i think multiple people are working on crypto libraries that take footguns out of it - which is what i think we definitely need. https://github.com/brycx/orion seems like a solid attempt at making crypto fool-proof , so i do have hope.

You're more than welcome to swing by at Orion (a pure-Rust crypto lib). You can also check the new Matrix room for a small chat.
