Hi! I am pretty new on Dlang and I wanted to make a small password manager that used some sort of encryption on a file (for example AES256) and save a password to decrypt it later, so you can copy the password.
I couldn't find any way of doing encryption on Dlang, is there a lib that's better for doing this? Secured and some other libs i tried didn't quite work.
I also don't know how I could store the password (for example in a SHA256 hash) for decrypting the files.

okay thanks i'll take a look at those libs but what about AES256? the crypto lib gave me some errors every time i ran "dub run" about the crypto lib "cannot call impure function 'core.bitop.volatileStore'"

Try different compiler options (version=??? to make the static assert true).

If still not working, log an issue on the library's git repo page.

I haven't done this specifically myself, but if I did, I'd probably use bindings to the C libsodium and let it do most the encryption work.

this looks reasonable but again I haven't used myself.

https://code.dlang.org/packages/libsodiumd

Since it is a simple binding to the C library, you'd use it the same way you would from C itself and can look up tutorials for that and easily translate to D.

Now this I have done myself, and again, I delegated the real work to a C library called argon2.

My library is https://code.dlang.org/packages/arsd-official%3Aargon2

And my docs:
http://arsd-official.dpldocs.info/arsd.argon2.html

If you get the C argon2 library installed, then you can use that D module easily with the encode and verify functions.
