 # goaes
 
 `goaes` is a very simple tool for encrypting files with AES-256 GCM.
@@ -20,32 +21,32 @@ I wanted to write some Go and encryption fascinates me, so I wrote `goaes`.
 
 ## how it works
 
-- it uses [PBKDF2](https://en.wikipedia.org/wiki/PBKDF2)
+- it uses [Argon2id](https://en.wikipedia.org/wiki/Argon2)
+	- time: `3`
+	- memory: `256mb`
+	- threads: `4`
+	- key length: `32`
 - it uses [key wrapping](https://en.wikipedia.org/wiki/Key_wrap)
 
 ## getting started
 
 1. Generate a new passphrase.
-2. Generate a new salt.
 
 ```bash
 goaes generate
