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'"

crypto prints the error i just posted last post, botan lib gives 
me this error:

Encryption

[noid via Digitalmars-d-learn]

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.
