Error: Decrypting large file: aead::Error routine

[HelixTP]

Hello I found a small error or omission in the decryption function, you forgot to add 16 bytes to BUFFER_LEN (based or you other code to encrypt file

const BUFFER_LEN: usize = 500;

to

const BUFFER_LEN: usize = 500 + 16;

Hello, thank you for the feedback!

What portion of the code are you talking about? Please provide a link to the file, because at least here: https://github.com/skerkour/kerkour.com/blob/main/2021/rust_file_encryption/src/main.rs const BUFFER_LEN: usize = 500 + 16; seems correct.

Hello, At line 126, in the main.r file.

But in the code of the blog the error is not there.

Line 126? https://github.com/skerkour/kerkour.com/blob/80f17624b1708b2ce9620af2a352afd92cae13cc/2021/rust_file_encryption/src/main.rs#L126

Non, in rust_file_encryption_with_password, need add 16 bytes to BUFFER_LEN

Thanks!

It's now fixed :)
